SOURCE: 95 GMC Jimmy 4L60E no 2nd or OD 4L60E

You might want to try this if its got a kick down cable unhook it from throutle body and pull it out as far as you can and let it snap back, do this a few of times, sometimes a valve gets hung up inside valve body of trans. and won't let it shift. If that don't help you may have to pull pan to dislodge it if thats the problem. chk. the plug on trans. (Its a 4 wire white plug) with test light with key on to see if there is power down there one will be hot, thats for overdrive, now on top of intake in front throutle body there is a sending unit that looks like a temp. sending unit with a 2 wire plug on it that sends a signial down to that plug when engine gets to temp. to let it shift to overdrive. Maybe this will help, or give you some ideas.

SOURCE: Need to change oil pan gasket in a 1998 GMC Jimmy 2 wheel dr 4.3

On many vehicles the exhaust runs under the oil pan, on others there may have a cross member in the way, or brackets that will hinder oil pan removal. These parts need to be removed. The exhaust nuts/bolts will most likely be rusted. It is best to spray them with penetrating oil. You can use WD-40, PB Blaster, Deep Creep, or something similar. After you have sprayed all of the nuts/bolts, let the penetrating oil soak in for about 10 minutes. Now remove the exhaust pipe that runs under the oil pan. The catalytic converter may, or may not be in the piece that you have to remove. If you have to remove a cross member, simply unbolt it and set it to the side, it is best to mark which side is the front, as some will only go on one way. Other than that, you should not have to pull the engine at all.



please rate this response and god bless.

SOURCE: Bad oil leak driver side front fender

There is an adapter for the oil filter with 2 lines coming out of it above the drive shaft from the transfer case to the front differential. The O ring on these will go sometimes causing loss of oil. Also check the 2 lines for leaks and cracks.

SOURCE: How do I reset

If you’re not interested in diagnosing your car, truck, or SUV Check Engine Light, or it’s already fixed, and you just want the engine light out, visit an auto repair store.

Most stores will have a universal Check Engine Light Code Reader that can quickly and safely reset check engine light trouble codes. It should take about 30 seconds and is usually free..

How do you change oil pump in 89 gmc 4.3 v6 s15 jimmy


I'm going to simply "spitball" an answer because i don't know WHY you think you need to change the oil pump.

1st, IF the oil pressure gauge isn't showing any pressure, or low pressure, AND there is no engine noises such as knocking or loud tapping, I would suspect a faulty oil pressure sending unit. IF there's a deep knocking sound then an oil pump isn't going to solve the problem. That is UNLESS it turns out to be what I ran across on a 1991 S10 4x4 with a 4.3. There was a "knocking" sound which I traced to the cover plate of the flywheel/flexplate. Turned out to have a cracked flexplate. Changed it and all was good.

I have a 1985 GMC that showed low oil pressure, yet there was no noises coming from the engine to confirm low oil pressure. I changed the pressure sending unit and it fixed the problem of "low oil pressure".

Now IF you're dead set on changing the oil pump, get ready because it isn't a 10 minute job.

You'll more than likely have to at LEAST raise the engine somewhat as (I'm guessing it's 4x4) the oil pan has a deep sump area for the oil pick up. This is so the oil pan can be shallow in the front area to clear the front differential and cross frame area.

Then you get to try to wiggle, twist, wiggle some more, the oil pan out from between the bottom of the engine/crankshaft, and the cross member of the frame AFTER removing all of the bolts that hold the oil pan in place.

IF it were me, I'd be almost inclined to simply pull the engine, at least part way out of the truck, to gain better access to the pan. AND you wouldn't be fighting trying to keep the oil pan gasket in place while doing the wiggle/twist putting the pan back into place.

Hope this helps.

2000 GMC JIMMY What controls turning on fuel pump


The pump is powered by the relay. The relay is grounded by the computer. It gets a ground signal for the first 3 seconds, then only if the computer sees oil pressure or RPM to know the engine is running.
You should be able to ground the relay and run the pump for several minutes. After 30 seconds you should be at max pressure.
Normal pressure is 15psi for a truck that has throttle body injectors such as a mid 80s model, and 65psi for trucks that have port fuel injection like yours.
You may have the wrong pump.

I have a 97 jimmy. my oil pressure drops when i stop and i have oil in it.its not low


Sounds like a cloggoed oil pump screen or a bad oil pump. I would flush the engine with engine oil fluch (can be purchased at any local parts store) change the oil and filter and see if the problem goes away. If not, you may need to invest in replacing the oil pump to prevent serious engine damage. Good luck

I have a 1996 GMC Jimmy. Fuel pump replaced (new) and still do not here the pump kick on. Can start and runs fine if Throttle body is primed with gas. Is there a relay? where?


yes, there is a relay, probably in the engine compartment battery relay box. If the relay fails, oil pressure will allow the pump to run, so the relay is likely to be your problem.

2001 Jimmy shut down while driving. The ECM1 fuse blew. Replaced fuse and it blew. disconected circuits related to ECM1 fuse. reconected one circuit at a time. Fuse did not blow and Jimmy started. Why?


The first thing you should do is to locate the oil pressure switch/sending unit.

It's a single wire terminal with plastic connect sensor from the engine block.


This switch serves two functions.

1) provide oil pressure reading

2) disable the fuel pump relay in event of oil pressure loss.

===

When this switch is failing to provide the correct pressure to the ECU. The wiring harness can overheat and eventually create a short.

ECM1 fuse blow is because the harness is grounding/shorting.

===

DO NOT drive the truck until you change the oil pressure switch.

After you change the switch,you should spend sometime to inspect the wiring between the fuel pump relay,ECU and fuel pump.


Please post up day on the comment window/page.

I will follow up on it later.


Good luck.
