Price to replace oil pump on 98 gmc sonoma 2.2l 5speed truck. Also what else is a good idea or has to be replaced while this job is done. Truck only gets about 5 pounds oil pressure after started


There are a number of things that contribute to oil pressure, the pump has very little to do with pressure. I will say I have seen a lot of issues with the pick up screen inside the oil pan becoming clogged. I would suggest hooking up a manual gauge to verify actual oil pressure, then if it is actually low I would remove the oil pan and check the pick up screen first. You're looking at 11-12 hours labor at a repair shop plus 100-150 for the pump if you want it replaced. Plus gaskets and oil.

Oil pressure is jumping from 20lbs to 0lbs,truck almost dies then the oil pressure jumps back up to 30lbs then back to 10lbs ,


To start, take the vehicle to a dealer and ask them to screw an oil pressure gauge into the block hole and check your oil pressure whilst idling and while driving it.
I have a 1993 and it does the same thing, but the problem is only the gauge itself.
If it is actually having such oil pressure fluctuations, you may have a defective pump, a clogged pump filter screen, or a clogged oil filter.
God bless your efforts.

Keeps blowing ECM1 fuse


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

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.

2001 GMC Sonoma Ext cab 4.3l, quit while running


Pull plug wire and install a philips screwdriver into the plug wire get it 1/4 inch away from a good ground and crank the engine over, is there spark? if so check that you have fuel pressure buy renting a fuel pressure test kit from schucks or auto zone and turn the Key to run position with the gage hooked up, it should read 50 PSI turn key off and wait 20 seconds should still have 20 PSI of fuel pressure, if no fuel pressure check fuel pump relay, then check fuse to pump. if you have a bad relay and are not getting fuel then check the oil pressure switch to see if you have oil pressure at the switch if no pressure then the oil pressure safety switch has died and needs to be replaced and should stark after replacing. If you have fuel then check the timing to see if you slipped timing belt.

POOR GAS MILEAGE


Have you changed the fuel filter? I know it sounds weird but a plugged filter will make a truck use more gas. The computer tries to compensate for less fuel by commanding the injectors to open longer. Also a plugged filter will cause excess back pressure on the fuel pump making it loud.. Good Luck.

I have a 95(ChVy)TaHoe but clacks real loud due to no oil Help!


It sounds like your lifters are stuck. Put a can of seafoam or trans fluid in the oil drive it 50 miles or so and change the oil. Use a good oil and see if this helps. If it works it don't hurt to do this everytime before an oil change. This keeps your engine very clean

Changed oil pressure switch,still no oil pressure


The fuel pump on that model runs through the oil pressure switch so that if the truck looses oil pressure,It kills power to the fuel pump to prevent engine damage.you need to find the cause of the low oil pressure reading(possibly a bad oil switch).That would be the cheapest place to start,or have it checked with a mechanical gauge.Good luck,
