Question From razorx on 2001 gmc envoy oil pressure gauge

i have a 2001 gmc envoy oil pressure gauge will drop after driving few miles r turning on a/c.no knocking smoking r power loss.can turn off car when this happens then start up and have pressure.just got engine flushed but still doing same.

Response From Hammer Time

just got engine flushed but still doing same.

That's a big mistake and should never be done.

The first thing you need to do is test the pressure using a manual gauge to find out if you really have low oil pressure or just a faulty gauge.

Response From razorx Top Rated Answer

they done it at a shop didnt replace gauge.i thought it might be oil pump screen r sending unit need help and advice please

Response From Hammer Time

I just gave you the advice you need.

Oil Pressure gauge

Question From jjlutz on Oil Pressure gauge

I have a 1988 GMC 1500 4WD with a 5.7 engine. When the engine starts up I have a little better than 30 lbs oil pressure. I plow with the truck, and after about 20 minutes, the pressure falls to a level that lights the "Check Gauges" light on the dash when it falls to an idle. Just today it would not come back up and turn out the light when engine speed was raised. I had just changed the oil before this started happening. There is plenty of oil in the pan, and the lifters don't seem to be starving for oil. The engine seems to be running well, but it is disconcerting to see that light on. Is it possible that the sending unit is bad, or is it more likely the oil pump?

Response From Hammer Time

I would first try changing the oil again and use a different brand this time. Some vehicles just don't like some brands of oil.
If the problem still persists, then your going to have to verify the pressure with a manual gauge to see if the sender is accurate. It might be even cheaper to just replace the sender to see if it helps.

Response From jjlutz

Thanks; Another issue may be that I put in 10-40 instead of 10-30 to try and boost the Oil Pressure. I live in Maine and it is COLD. I should try and go back to 10-30?

Response From Hammer Time Top Rated Answer

It won't be too serious with a truck that old but that would be a real problem on a later model.

Response From jjlutz

Thanks Hammer Time . . . . I pulled the sending unit off and hooked up a mechanical gauge and it blew the gauge to its highest mark. I put in a new sending unit in and it seems to be working fine. I'm glad it wasn't the oil pump. That would have been a big replacement job, especially with a foot of snow on the ground. Thanks again.

Question From Willybill on 98 GMC quit @70mph-no start

1998 GMC K1500 5.0L 144,000 miles, The plugs and wires were changed 4 months ago.Quit going down the road and had to be towed. It would crank, but not start. I ckecked the plugs for spark and didn't have any so I checked the distributor cap and rotor and they needed to changed. After changing them I had spark at the plugs, but it still wouldn't start. It cranks over 3 or 4 times then almost stop before turning over 3 or 4 more times and do it all over again. My son thinks it jumped timing.

Response From Sidom

If you have zero pressure after running HT's test, a backyard trick you can try is to get a good sized block of wood or dead blow hammer & beat on the bottom of the tank (being careful not to damage the tank) where the fuel pump rests. If it starts that would confirm a bad pump.....

If it does start.....don't drive it, replace the pump, it will just stranded you again.............

Response From Willybill

Thanks, Hammer Time & Sidom, it took awhile to get a pressure gauge, it tested at 60 psi while cranking and didn't start The pressure slowly drops, it takes awhile to get to 50 psi. The camshaft and crankshaft sensors have been changed. There is voltage to the ign. module is about the same as battery voltage. What else is there to ckeck for?

Response From Hammer Time

First check for spark. If you have spark, try spraying some starting fluid into the intake and see if it fires for a moment on that.

Response From Willybill

Yes, there is spark and it does fire with starting fluid.

Response From Hammer Time

Ok, that narrows it down to a fuel problem. If you are sure the pressure is maintaining from the pump and the fuel itself is not bad, then we have to concentrate on the fuel injectors. Check all your fuses carefully. You may need a scan tool to see what the PCM is or isn't doing.

Response From Willybill

After reading other posts I decided to check the distributor gear and found it to be very worn. I am in the process of putting it back together. I know #1 cyl. needs to be at top dead center, but how do I know if it is on the compression stroke without taking the valve cover off on that side? I can't see the timing marks because of the AC and power steering pumps and bracket. If it stops raining because its not suppose to be raining, I'm going to work on it today.

Response From Sidom

Everything HT said is correct.......

I'm going off memory here so take it with a grain of salt...... Some 5.7s still have timing marks under the water pump and some don't...... Take a look, if your's does then this should work....

Pull #1 plug & bump the engine over until you feel compression coming out of hole. Then put a ratchet on the crank and roll it over to TDC on the marks. Now the dist is ready to be put in.....

Were gonna back up just a bit for a sec..... Some 5.7s had a factory white line on the dist & intake. It was on the backside so you would need a mirror to see.....If yours has one you're in luck. If your replacing the dist put a white line on the EXACT same spot at the old one.

Ok back to the install, look down at the dist and on the plate somewhere you should see a 6 and the over a bit an 8. Face the rotor tip at the 8. Lining up the 2 white lines between the dist & manifold set the dist in and this should set it to #1. You can verify but looking in the cap and tracing where the #1 wires goes into to cap and where the #1 electrode is. The cap is a weird design but you'll see what I mean. If the distrib doesn't go all the way down then the oil pump drive isn't lined up. you can either pull the dist and use a screwdriver to line it up or what I do and just have someone bump it over (not crank) until it drops in. Then just bring it back up on compression and make sure the rotor is pointing at the #1 electrode. Line up the 2 white marks and you should be good.

No white lines and you will need a scanner that shows the cam retard PID to set the timing. If it's off it will set a P1345. You can't use the marks on the balancer, that won't work.....

Response From Willybill

Have been working at getting the dist. to drop into place for the last 4 hr. Got any secrets?

Response From Hammer Time Top Rated Answer

Once you get the teeth in the gear started, hold a steady pressure down and have someone bump the starter. The cam gear and the oil pump drive never align together because the distributor turns as it drops. You'll have to estimate where the rotor is going to land when all the way down to pick the right tooth.

Response From Willybill

Well, its been a week since I had a chance to work on the truck. I have a job 4 days, 10 hours a day, and a little rain some wind and flurries and time goes by. Having difficulty with the gear on the end of the distributor lining up with the oil pump, once I got everything in its proper place it did go together quite well. It was just as Sidom said, all the marks were there. I had not seen the 6 and 8 before you told me, the 8 was not real clear. The truck starts right up and idles good. I just hope the new gear is better than the old one. Thanks for the help, this is a great site.

Response From nickwarner

thanks for posting the fix, and glad your truck is back on the road

Response From Hammer Time

There are no timing marks because the timing is not adjustable at all. The distributor synchronizes the rotor and the Cam sensor and it requires a professional scan tool to get the distributor set correctly once removed.

Response From Hammer Time

That would be very unusual for that engine. I would first get a fuel pressure gauge and test the fuel pressure. This is a high pressure system and requires a minimum of 55 PSI to even run. The pumps fail quite often.

96 gmc Sierra

Question From bigrich1356 on 96 gmc Sierra

I have a 96 gmc sierra 1500 2 wheel drive with a 5.0 vortec engine 160xxx. I bought it last spring with no problems, everything was running good, no check engine light or anything wrong, well the guy neglected to tell me the oil pump was no good and i blew the engine, so i put in a newer engine and now the check engine light is on with trouble codes (P0135, P0140, and P0141) the only o2 sensor i unhooked was the bank 2 sensor 1 b/c the wire runs behind the motor and i didn't want it to get pinched but its the bank one side where the codes are, i checked the wires and they look fine, the truck runs fine, but every once in awhile the check engine light will go off for a day our 2, any idea what might have happened in the week it say while changing out engines that would cause them codes to come up? And what should i do to fix it b/c my inspection is about to run out?

Response From Hammer Time

Have you tried clearing to codes to see if they all come back?

Response From bigrich1356

I cleared the codes twice but they come back within 5 miles

Response From Hammer Time

I would verify that these sensors are plugged in firmly. I doubt you have 2 bad heaters so check all your fuses. If they are OK, test for power and ground at the sensor at the 2 like colored wires.

Response From bigrich1356

I unplugged all of then today to check to see other were dirty but they were all good, and i put em back together pretty snug... The only fuse i could find in the book is for the (heated o2) in the engine compartment but that was fine, should there be a fuse anywhere else?

Response From Hammer Time

You should use a test light to test every fuse in the car.

Response From bigrich1356 Top Rated Answer

So it could be something stupid that has nothing to do with the o2 sensors?

97 suburban oil pressure

Question From c_robinson on 97 suburban oil pressure

1997 GMC
suburban
5.7 l v-8

My oil pressure gauge is acting up. When I first start it it's fine, but as I accelerate the pressure rises(up to 40psi), but if I slow down or stop it plummets to 0psi. Do I just have a gauge going out or do I need to look at an oil pump. Anyway to troubleshoot this, I'm not much of a mechanic outside of light maintenance.

Response From Double J Top Rated Answer

Connect a mechanical gauge and take the reading that way.
This will determine if there is an engine oiling problem or just a gauge and/or sender problem.
