Have read all over about the stalling problems, I wonder if anyone has any suggestions and if I'm looking at this correctly, this seems to be the best site around.
1995 Chev Reg Cab 4X4 Pickup, 205,000 km.
Started stalling about a week ago, would do it on the highway after about 15 km, would also stall just going down the street after a few minutes after truck has been parked about an hour. Check engine light doesn't flash so no codes.
Changed the fuel filter.
Now, it has not stalled as often after putting in the fuel filter, but still does.
A couple of times it wouldn't start (shook some wires under the A/C and banged where the lift pump is and it starts, still it sometimes stalls after going a few blocks, then starts, stalls again, then starts and is fine for the rest of the day. ALSO when it starts to stall on the highway (engine light goes on, no power) I press the accelerator once or twice and it has kicked back in. (sometimes feel a bit of a miss or buck a few minutes before that)
Now when I put the fuel filter in, had a heck of a time starting it til I called GM and the guy gave me a hint how to get it going (fill the filter chamber, inject a bit of air in the gas tank and it started) but he did say my Lift Pump is probably gone as it stalled when I opened the valve to remove the water and it would not prime when I tried to restart it.
I have read alot about the PMD going bad but usually after the first stall or two it runs fine the rest of the day.
Now I want to change the Lift Pump but I have also read that it could be the Oil Switch that is located near the Lift Pump.
So...
Could the switch and/or the Lift Pump be causing the stalling ? Should I change both and is there a way to test the switch and where is the switch located.
I really like the truck but it's certainly unnerving reading all the problems these are having ant the GM techs that can't figure it out.
Thanks in advance for any help or suggestions, it's VERY much appreciated.Edited by: 95 Diesel
