1000 miles/coil! '94 Jeep Grand Cherokee

Showing 2 out of 4 Posts | Show 2 Hidden Posts

Question From bk on 1000 miles/coil! '94 Jeep Grand Cherokee

I'm posting on behalf of a friend who has a high mileage '94 Jeep Grand Cherokee.

It has blown through 5 coils in the last year. It will just quit. Replacing the coil always fixes the car. At $40/coil it is getting expensive.

How and why is this happening, and I'm open to suggestions that might help solve this problem!

Response From Double J Top Rated Answer

Check/replace the spark plug wires/coil wire.Any arcing on a old spark plug wire and/or coil wire will cause carbon tracking and can cause a new coil to fail.Arcing at the coil tower will cause the wire to carbonize and take out the coil.
If they haven't been replaced in a while,i would toss 'em and install a new set along with a new set of spark plugs.

Just a thought!

See what the others say

Jim

Response From way2old

ALong with Jim's advice, look for a weak ground to the coil. As Jim stated, bad wires or plugs can cause the coil to work too hard to produce enough voltage to push the current through.

Response From Jeff Norfolk

I also agree with above along with chunking the Autozone garbage and buying either a factory or AC Delco replacement. I have had the same trouble with this type of car when installing lower quality coils. Spend a few more dollars on a good one and be done with it.

1991 Jeep flooding

Showing 2 out of 8 Posts | Show 6 Hidden Posts

Question From ace13567 on 1991 Jeep flooding

hi i have a 1991 jeep yj that has bean siting in the driveway for a year and a half and it turns over and has spark but it will not start and then when i take my spark plugs out there flooded.

Response From Tom Greenleaf

What comes to mind with long term storage like that outdoors is bad fuel - additives that was put in the fuel causes problems and may after even one flooding so it didn't feel like starting and sometimes even with spark the plugs won't work. They get the spark but won't make a good spark. If it was running ok when it was put there I would probably just put new plugs in it and mark your wires (masking tape or something) and leave the old plugs out for a day!

Also - I've seen hydraulic lifters compress and the valves don't work well but should again. It may take some serious cranking but go slow as you don't wan't to burn out the starter. You can heat up plugs with propane torch but it's generally not worth the trouble vs new. Use a bit of good old starting fluid in air intake but replace the air cleaner as it's also a spark/flame arrestor.

This is a place where I will suggest a fuel solvent and it may need a while to burn up the old fuel but get rid of it, by using it up or drain it.

You'll get it going and then check out the tire pressure, battery, change the oil in an outdoor stored car and you may need to do some brake work too. Vehicles don't like sitting around and some problems may show up but just one year may not be too bad.

Let us know how you are making out and expect some different problems till you hve used it some before you give it your full trust. Good luck, T

Response From ace13567 Top Rated Answer

Ya before I tried to start it I changed the spark pugs and spark plug wires, checked the coil and cap and rotter, and also I took the valve cover off to check that all of the valves were working and did an oil change with the valve cover off to make sure that there was plenty of oil on the push rods, valves, and rocker arms. So my guess is also that it is bad fuel.

Also do I have to drain the tank or will adding more gas be enough?

Response From Tom Greenleaf

I've never been able to get all the fuel out of a tank and the problem may be between the tank, fuel filter, injectors and I you can get away with it it's a whole lot easier to use solvents but they have to move along. SeaFoam is an awesome product and you may have water from condensation and time (this jeep isn't new anymore) and it gets into. One year old gas is old but I've dealt with some five year old gas that was a pest. The solvents should work if this is it. Use only isopropyl achohol based water remover. Methanol just prevents the water from freezing but doesn't remove it.

If starting fluid doesn't get you some reaction we may be barking up the wrong tree here. None of this work will hurt though and we'll keep trying, T

Response From ace13567

Yea I got my jeep running after replacing the fuel filter and adding some of that isopropanol stuff to the tank. And it runs fine except for one of my valves is ticking and I was wondering how exactly to fix it?

Also my power steering fluid is low and my Haynes Manuel says to use â€œJeep power steering fluid (or equivalent)â€ which what would classify as equivalent?

The valve may be fixed with just changing the oil too much or a solvent which I don't wan't to recommend right now. It could be sludge, bad lifter or not nice a worn lobe on camshaft.

Where was the PS leaking? You can use just trans fluid or the product that works for 100K now in my own car for a shaft seal called TransX. It's just a maybe and won't fix a real leak in a hose and may not work but I haven't found it to hurt anything. It took several tries before that TransX worked but it has in now a low use car of mine with a bazillion miles on it. I generally don't believe in additives except for water removing dry gas.

Just new oil is a slow cleaner of your engine. Fast stuff may throw too much junk at once and cause problems again - some fatal for the engine. The ticking valve could just be a loose plug and you can see them wobble and they can fall out which will wake up the neighbors!

The real fix if you need this car bad is to replace the bad parts - I don't drive much further than I can walk and I will try some tricks on my own cars. Ok - that's my own cars all old, but the real fix is new parts. Good luck, T

Ya the only reason why the power steering fluid is low is because the jeep used to belong to my brother which he doesnâ€™t know much abought cars and did some work of his own which he wound up loosening off the 2 bolts that hold up the reservoir so it was siting upside down.

Response From Tom Greenleaf

That would explain some problems.!!!!

Just for readers of this thread that was a different problem but all cars/vehicles with PS should never be forced when at the full end of their travel as they are stupid and will just make unreal pressures that can only cause problems. T

1993 Jeep Cherokee will not start???

Question From 93JeepCherokee on 1993 Jeep Cherokee will not start???

Hello all,

I have a quick question that hopefully someone can guide me in the right direction. I have a 1993 Jeep Grand Cherokee Laredo 4WD V6 that doesn't seem to start. When I turn the key their is ample amount of juice (cranking) but the vehicle will not start. I changed the distributor cap and electrical cylinder inside with no luck. One thing I did notice was that when I turn the key to the power position (not cracking the engine but able to listen to the radio) my tachometer (RPM's) is at a constant 2000 RPM's??? Does anybody have any suggestions?

Your first step would be to check for spark at the plug end of the spark plug wire. Then, check to make sure you are getting fuel to the injectors. (check all of your fuses...could be a blown PCM fuse, but rare). Jeeps and Chrys. products have a problem with crank sensors. Just a thought. Let us know what you've found. How was it running the last time you drove it. Has the check engine light been on? (crank sensors don't always set a code).

check your plugs firing order

Wet Weather Jeep Problem

Question From redlaredo on Wet Weather Jeep Problem

I have a 91 cherokee laredo, 260k+, 4.0, straight 6 automatic, 4wd. It runs fine outside a few quirks, but when there is a heavy rain or i drive through puddle, the engine will sputter for the next couple of hours. it will still run, but acceleration is difficult. any advice?

Response From Tom Greenleaf

The first likely problem items are the high voltage items like plugs, wires, cap, rotor and coil(s).. Sometimes you can see them "arcing" when dark or perhaps plain sight now. Note: The longer you run an engine that is misfiring for any reason the harder it is on you convert(s) up to killing them and o2 sensors,

Response From redlaredo

i dont understand...what plugs, wires, caps, rotars, coils are you talking about and what is wrong with them? what do you mean arcing? are you saying those things are getting wet and therefore causing some kind of problem?

Response From Tom Greenleaf

Electricity just naturally seeks the easiest way to ground. In car's ignition system the high voltage of the items metioned need to insulate that charge to fire the spark plugs. If it doesn't get there or leaks between any errantly it won't fire properly or sometimes at all.

All but about distilled water conducts electricity. Ever see the warnings about using electric things in or near water even at home?

Temporarily spraying some WD-40 (water displacement is what the WD stands for) can correct the problem especially in near invisable cracks or carbon traces on any of those parts.

The dampness could be affecting something else electrical. The most sensitive is the ignition and it's components,

Response From redlaredo

i appreciate your advice and insight, but im not really sure about what your telling me to do. just spray some wd40 on some stuff? spray it on what/where? if that is the temporary solution, whats the long term solution. if i wanted to take it off-road im afraid id have some trouble with it stalling and/or possibly dying after getting wet+

Response From Tom Greenleaf Top Rated Answer

WD-40 is a maybe for a temp fix and just might as it seems to correct when dry again.

You would spray on distributor cap, coil tower(s) and along spark plug wires. It's flammable so best done with cooler engine and don't aim at hot exhaust parts especially.

That is as old as the product by brand but sold as "wire drier" still I think under assorted brands. For the most part the brand WD-40 won't hurt anything - can't speak for others.

The fix is to replace the items that have the faults. No patch I know of will last,

T

Response From redlaredo

how do i know which part(s) are causing the problem?

Response From Tom Greenleaf

If it is jumping electricity out of a wire or between them or at the cap you may see it as a spark. When you have the problem you could just spray one item at a time and the one(s) that make it correct the problem should be replaced. If you find a plug wire that has a spot rubbing thru or something like that on a budget you can get just one wire.

The other way to find WHICH item is causing it is to spray plain salt (table) water on suspect parts when it's running well and the one(s) that make it repeat the problem may show right up for you.

It may not be the high voltage ignition stuff at all and could be wiring to some other sensor usually at a plug/connector that is weak or making a poor connection.

You said you can get this problem right away from hitting a puddle so anything that might get wet from that is highly suspect. Many vehciles won't wet the engine much or at all with ordinary puddles.

If you want my guess on which part right now I'd blame the distributor cap. They get hairline cracks sometimes from being shocked with cold water on a hot brittle plastic part and will behave when dry again and misbehave when wet again.

Note: Problems when moisture is the trigger are almost always electrical and not mechanical problems,

Spark plug wires stuck, and don't get me started on the distributor cap...

Question From coastiewithjeep on Spark plug wires stuck, and don't get me started on the distributor cap...

So, I'm attempting to do a tuneup on a 1995 Jeep Cherokee Sport with 150,000 miles. The screws/bolts holding distributor cap are corroded and rounded to the point I can't even get a socket on them. Any ideas? Seeing no carbon tracks I decided to at least get the plugs and wires changed today. I can't get the wires off. Even with the cheap plastic wire puller I got at Autozone (it just slips right off). Does anyone have any advice on how to get these wires off? The #1 is right under the hose to the radiator. Would I normally need to drain the radiator to get a plug wire off? Seems excessive. I can twist the wire but it doesn't seem to want to come off. Perhaps I just need a better wire puller?

Response From coastiewithjeep

OK, after short break I went back at it and realized I just wasn't pulling hard enough. I tossed the cheapo spark plug puller and used a pair of channel locks (I was replacing the wires anyway per another of my posts on this forum). The #1 and #6 wires are tricky due to their location but they are manageable. I still haven't determined what to do about the distributor but there are no obvious carbon tracks or cracks on the outside. The spark plugs and wires are now replaced and the engine is running noticeably smoother.

Response From redfox81

I don't know how you'll like the sounds of this as it seems a little radical but it worked for me as I had the same problem. I first bought a new cap, rotor, wires, spark plugs and some silicon grease plus a small bottle of rubber glue. I took a flat tipped screw driver and hammer and gently broke the outer part of the cap away from the screws and removed the cap and rotor. Then I used a pair of small vise grips to lock onto the cap bolts and removed them. I then inspected for any damage and seeing none, Put the new rotor and cap back on. Then I coated the cap terminals with the silicon grease as well as the spark plug tips after installing them. Next I put some rubber glue on the cap screws, put the wires on and haven't had a problem since. When doing stuff like this, be careful, wear protective eye gear, work like a surgeon, not "Grog" the caveman. Good luck.

Response From Tom Greenleaf Top Rated Answer

I have good luck with a penetrating oil called PB. Yes when you are replacing a part like that and you just can't get a grip on the bolt or screw breaking it off works. Go easy though as it that sucker breaks off flush you'll have hell to pay to extract the broken stud left in there. Try a selection of sockets that may just hammer down over rounded stuff and that can work to grab it. Again go easy or you may need another distributor over that!
