2000 Pontiac Ignition Problem

Showing 3 out of 3 Posts
Question From cpharr on 2000 Pontiac Ignition Problem

I have a 2000 Pontiac Bonneville, 3.8, 118k miles and it is not firing on 1&4. I can pull the wires from the ignition coil to verify this, so I replace the coil and still have no spark from this coil. What else can cause this, maybe the Ignition Control Module? If so, where is it located at and how can I verify that this is what I need without buying one first?

Thanks in advance for any help.

Response From autojoe

  1. Install a spark tester at the spark plug end of the ignition wire associated with the misfiring cylinders hooked to good ground.
  2. Jumper the spark plug end of the companion cylinder ignition wire to engine ground. The companion cylinder is the cylinder that shares the same ignition coil (i.e. 1/4, 2/5, 3/6).
  3. Crank the engine while observing the spark tester.
  4. Then reverse and see if spark on both 1/4.
  5. Measure the resistance of the ignition wires associated with the cylinders that were indicated as misfiring. (1000-1500 ohms per foot)If not in spec. replace wires.
  • disconnect the ignition coil for cylinders 1/4.
  • Connect a test lamp across the ignition module primary circuit terminals.
  • Remove the fuel injector fuse.
  • Observe the test lamp while cranking the engine.

  • Does the test lamp blink?
    If not,replace Ignition control unit.All connections tight where coil sits on module terminals and also electrical connections.?Secondary resistance of coil should be between 5-8,000 ohms.
    They do make dis ignition module testers but pretty expensive.I don't know if any local parts stores have them.Could call and see.ICM easy to replace,just remove coils and then remove ICM.I usually check coil if having a problem with one is switch coil and see if problem follows coil.Just some thoughts.

    Response From Loren Champlain Sr Top Rated Answer

    My first instinct would be the control module, BUT, have you pulled codes yet? Could be a (PCM) driver problem.
    (The control module is what the coils are mounted on).

    Question From Jamik on 1986 Pontiac Parisienne starting trouble.MAJOR!!

    Would anybody know if a faulty HEI Module would cause the problems that I've mentioned in my previous post?? I have been told this could be a possibility.

    It is an almost all electric carb afterall!!

    Just a thought!!! Jay

    Response From Tom Greenleaf

    Those things are usually go or no go but now not expensive and pretty easy to replace. I keep a used one in my trunk that fits most HEI but not all. I've NOT seen one fail part way. Just my experience. T

    Response From Jamik Top Rated Answer

    Well I think your right, because I checked the Ignition Coil, and there was absolutely no ohms of resistance between the BAT terminal and the distributor pin.

    As far as I know, that's a sure sign the coil's no good! Changed it with a replacement one, spark seems stronger!

    Still looking into Vaccuum leak! Will know more tomorrow. Car at least driveable today!!

    Thanks for your reply! Jay

    Ignition coil problems

    Question From top_jimmy44 on Ignition coil problems

    Hello. I am having problems with my ignition coil.

    Car - Chevy Cavalier - 1999
    2.2 L engine

    The problem started two weeks ago. I took my car to get the AC charged and the next morning, the car would start, but as soon as I put it in gear, it would sputter and stall. If I got the car up to speed, it would run and I could drive it, but it was still bogging down on hills and was very difficult to get up to speed from a stop.

    My mechanic replaced the spark plugs and wires but the engine still gave misfire codes. He then replaced the ignition coil and it solved the problem.

    A week went by and when I woke up this morning, the problem came back. I did not notice any problems with the car up until this morning when I tried to start it up. It did start and I was able to drive it to the shop again, but still had the same problem. The mechanic gave me a replacement part and I installed it and the problem is gone again.

    He said that if it happens again, we could look at it and see if we could figure out what is frying the coil. It is only happening to the coil for cylinders 2 and 3. The coil for cylinder 1 and 4 is original and has never been replaced. What could possibly cause this to happen? If it was a defective part, that would make sense, but if it happens again, what should I look for?

    Thanks.
    Jim

    Response From DanD

    It very well may have been a defective coil?
    But it also could be the ignition module that may have a poor internal connection for the coil driver.
    A coil driver is an electronic switch inside the module that turns the primary ignition coil circuits on and off, every time a coil needs to fire.
    If this is a connection problem at or inside the module; that would explain why the car ran ok for a week and the started to act up again.
    By you replacing the coil; you inadvertently disturbed the connection, allowing it to work for a while?
    The only way of proving this would be to replace the ignition module and see if that’s it?
    There are other possibilities that could be causing this as well; like the ignition divers inside the PCM (computer); these drivers tell the ignition module, when and which coil to fire?
    The joys of electronics; their not all that bad to diagnose when something burns out but intermittent problems can be a nightmare.


    Dan.

    Response From top_jimmy44 Top Rated Answer

    Dan,

    Thanks. I kinda figured it wouldn't be easy. If it turns out that the ignition module is causing the problem, I would most likely search local junk yards for a replacement. Do you know what years, makes and models have the same module as a 99 cavalier? If I remember right, the Pontiac Sunfire shares some of the same parts but I wasn't sure about the module.

    Thanks again.

    Jim

    Response From DanD

    You’re right about the Cavalier and Sunfire being more or less the same car; a 2.2 is a 2.2lt. But if you’re going to try a used module; make sure it is the proper (exact) module for your system. Even if the replacement looks identical and will plug in; but a year or two different then yours, it may not be the same electronically.
    I’ve even have had trouble with new aftermarket modules when forced to use them; as in tripping check engine lights for no apparent reason, poor fuel mileage and overall poor engine performance issues.
    There’s a reason why some of the aftermarket modules are less expensive (what I’m not sure), then an AC Delco (GM) module and it’s not just because they don’t have the General’s stamp on it.

    Dan.

    Response From Tom Greenleaf

    http://www.partsamerXXXXXica.com/...mfrpartnumber=CBE120 That link didn't work from here so you can check the advance auto site for parts and that perticular parts house show what parts will fit other cars.

    If that helps it shows what years and vehicles the ignition module fits or is supposed to work with for aftermarket and if you are going used you could check just those vehicles and look or an OE one....

    Question From Dayleh on '86 Pontiac 6000 LE

    have a '86 pontiac 6000 LE with 2.8L and 2 barrel carb. The past few days the car has been hard to start, but would finally fire. I pulled the distributer cap off one day and found quite a bit of corrosion on the rotor and the metal tabs in the distributer cap. I replaced the distributer cap and rotor. The car started easier for a couple of days. Now it will not start at all. I pulled a couple of the spark plugs which were completly black with carbon. Bought new plugs and wires but still won't start. Pulled the fuel line loose from the carb. and their was no fuel there, but when I turned it over fuel sprayed out of the line. Since I had this line off I went ahead and changed the fuel filter. I tried spraying a little starting fluid in he carb. but still wouldn't start. I noticed that after spraying the starting fluid that it had coughed and sprayed out of the carb and even had a flame shoot out once. Any help would be great.
    Thanks Dayle

    Response From Tom Greenleaf

    That carb uses choke pull offs (think two) and they fail routinely and will over choke the car. Retract them and put your finger over the spud for vacuum and they should hold. If not -- especially the primary one will cause lots of problems as you described. Some to leak down slowly and that might me normal. Primary should work immediately and secondary when the engine warms up a bit. Proper adjustment is tricky and if you find them bad don't trust them out of the box. Drill bits can be used on a cold engine with a vacuum source to check them but holly cow do NOT drop a drill bit into the carb!!!!!!!!! T

    I have tried both of these and they both stay when a vacume is present. I have also tried a different ignition coil, but this din't not help.

    Response From Dayleh

    I have also tried a new ignition control module, again with no change.

    Response From Tom Greenleaf

    Arggh! How many miles on this car?

    T

    Response From Dayleh

    There is 103000 on it. I have found that the timing is off on the car, either the timing chain has sliped or is broken. Thanks for all your help.

    Response From Tom Greenleaf

    I was worried about the timing chain I have seen them go many more miles and it's tricky to diagnose without seeing it. Most origs use a nylon gear and the replacement won't. Engines with real chains will still run if off a tooth or two but that's about it.

    Trying to think of some tests with a cold engine for this................

    * Can't recall what cranking vacuum should be but it may be normal at about 14 Hg and would be 18ish running and warm but we can't do that.

    * A compression test that shows all way too low would be a clue also but that also should be done with a warm engine. I would try the squirt of oil and if it's jumped that won't help it.

    * Some you can feel thru the fuel pump if removed and turn damper to you are touching the slack -- Not sure if you can on the 2.8

    Hate to see you get into all of this and that not be it. ANY MORE IDEAS ANYONE?

    The timing being off is a clue. If you set it right it may run but you would always set it back to where you started and can be done with just a cranking engine. Not perfect and recheck with it running to spec when problem is solved.

    Most orig chains go more miles but not all! Any history of overheating or if it's already been done?

    Good luck, I'll think of what else for diagnosis and post it. Dang -- only one in a career caused a car not to run and all the rest were highly sympomatic or I just replaced them when a car had some miles if it needed a water pump as you are part way there, T

    SOLVED ~ 2004 Pontiac Grand Am V6, Engine Misfire Cylinder 5 ~230 000 KM

    Question From WailFin on SOLVED ~ 2004 Pontiac Grand Am V6, Engine Misfire Cylinder 5 ~230 000 KM

    Let me start this by saying I'm not super mechanically knowledgeable, but if you give me some suggestions, I can figure how to go about getting them done!

    The car hooked up to a computer says that it shows a cylinder 5 misfire. Whenever you stop and start accelerating, it shakes extremely bad while it gains speed, and while going at higher speeds, ie: highway driving, or going up hills, it starts to hesitate and act sluggish, while the service engine light is flashing.

    Stuff I've done to try and fix it: replaced fuel filter, spark plugs, spark plug wires, ignition coil for cylinders 2+5 (when I changed it, it got mildly better for a couple hours, the misfire was gone on the computer, but the next day it started up worse than ever), fuel injector cleaner (multiple bottles), and the only other thing I can think of is a fuel injector, but as it's one of the back one it requires taking off the entire manifold and everything else, which is above my mechanical ability, and it's apparently a time consuming process.

    We also tested the compression on cylinders 1, 3 and 5 and they were all around the same apparently, and in a good range.

    I've also posted this on Yahoo Questions, but I feel like maybe this is a better place!

    Anything else you can think of to help me is greatly appreciate!

    Response From Hammer Time

    I'd probably agree that is sounds like a fuel injector. Don't waste your money on chemicals in the fuel tank. There is no such thing as "Mechanic in a Can". The only one that benefits from that stuff is the guy that sold it to you.

    Response From WailFin

    That's what I was thinking, but I can't always be a hundred percent certain which I why I tried the other little "quicker" stuff to try all my options, and why I've turned to here to see if there's anything else someone can suggest.

    The process for changing the fuel injectors seems pretty invasive, requiring the manifold to be taken off and everything like that. Do you have any idea on how long that would take?

    I figured it was worth a try, right? ;) Some people like to swear by it.

    Response From Hammer Time

    The flat rate time on it is 2.7 hours. You probably want to pick up new O rings the the other injectors because once you disturb the seals, they will likely leak. Blow all the dirt around the base of the injector very good before removing it and apply some dialectric grease on the seals when going back in, not regular grease!

    Response From WailFin

    I got told a lot longer than that whenever I talked to a shop. Well.

    Do I replace just the one that's gone bad, or go in and buy the other five, plus seals, and I also got told that I'd probably need a new manifold gasket as well.

    Also, thank you for being so helpful!!

    Response From Hammer Time

    It's only the upper intake (plenum) that gets removed.

    If this was a customer we would recommend but not require that all the injectors get replaced, simply because it's so much labor to access them again. If one is plugged up, it's not unreasonable to think others might be also but it's your decision. If you can handle taking it apart again if another one goes bad, then just change the seals.

    So I figured I'd give ya an update.

    I tried one last thing to see if it'd fixed it before relenting and taking it to a garage. A guy I know who works at a scrap yard mentioned that I might need a new distributor pack? At least, that's what I think the same in. The little metal plate that the ignition coils bolt into, at least.

    We took the old one out, fixed some shoddy wiring where the small cord on the left hooks into it (cleaned up the wires, respliced them), put the "new to me" one in, with the "new to me" ignition coils, and put everything all back together. We plugged it in to the computer to reset the code, then took it for a quick drive on the highway to see if the misfire came back - AND IT DIDN'T!!!

    The piece had been replaced previously (a problem with the V6 engine, perhaps?) So far the car seems to be working just fine, and the only other things I need to do are just some basic upkeep. I will keep the fuel in

    Response From Hammer Time

    That would be the ignition Control module.

    Glad to hear you got it fixed. I will close this now as solved to keep the spammers out. If you need it reopened, just ask any Mod.
