    i had the same problem in my 95 with the 4.3, it would take forever to start and then once the oil pressure went up it worked great. and sometimes when i shut it off i had to wait 20 minutes before it would start again. i took it into the shop and my mechanic found a bad relay, cost me 68 dollars to get fixed and now it works great.

Could be the fuel pump relay. Some of those trucks have a backup system that works through the oil pressure sending unit.

Oil pressure


If the manual T gauge is giving a higher oil pressure reading than the gauge on your dash - believe the manual gauge.

The oil pressure gauge on your dash receives a signal from an oil pressure sensor. It may well be that the oil pressure sensor is faulty

When stopped at a stop light my oil gauge goes down and my temperature gauge goes up on my 94 Chevy 1500 truck. I just changed the oil yesterday? What could it be?


Both issues could be normal to a degree. The engine temp would go up some when the truck stops moving, and the oil pressure would go down some when the engine returns to idle.
Are the two gauges reading out of normal range ?

96 chevy cheynne 5.7 vortechas about 40to50 pounds oil pressure when first sart in morning and when it gets to temp. it drops to 20to25pnds and at a stop it goes to 0 and gauge light comes on until i give...


Well it could be the sending unit for the gauge.
But odds are the oil pump or engine bearings are worn out.
As the engine warms up, the metal spaces expand and the oil gets thinner. The oil pressure drops some under normal conditions, but not more than 10 or 15psi. Normal idle pressure with the engine warmed up is probably 25psi.
You could check oil pressure with a mechanical gauge to make sure its not the sending unit.
Once the oil pressure starts staying below 20psi for long periods you'll start hearing noises.

94 chevy 5.7 4X4 has oil pressure at 40 psi when starting engine after warming engine oil pressure drops to 15 psi no engine noise?


15 is ok at idle, 10 will return the light on in the cluster. I would not worry about it unless it goes lower. The causes can be worn bearings, but if they were that loose you would hear a know for a second on cold start. Have you checked the pressure with a mechanical gauge to verify the notoriously inaccurate electric system

94 f350 7.3l turbo diesel looses oil pressure as rpm increase


Before you spend money on a new gauge. Get an oil pressure testing gauge for $20 , remove the oil pressure sending unit and test the oil pressure. If oil pressure at idle and 3000 rpm's is a-ok via spec's ( big money repair items) then its either the gauge a clogged or defective sending unit or the circuitry. (little money repair items)
You can also have this done at a repair shop.

Chevy 4.3 fuel prombems..?


I'd be replacing oil sender. GM have used oil pressure switch as a safety shut-off to fuel pump, when oil pressure drops off, as it would in a collision, due to engine stall.
