So..... you replaced the pump because it stalls, or it ran ok, and you replaced the pump and now it stalls? Stalls going 50 mph? idle? hot? cold? ck eng light on? codes? Fuel pressure?

Start with the fuel filter. Sounds like its on its way to the big filter bin in the sky.

I need much more information to answer your question. Is this problem constant? Is the engine light on or did you retrieve any engine code/s.
If so what are the digits?
What is the history of the truck? The truck is 11 years old, what is the mileage on it? Does the engine use oil? Could be a clogged CAT.
When does it stall? Does it matter if the engine is hot or cold?
Does the engine idle smooth or rough? Is there a misfire?
Have you checked the engine out for any noticeable problems? Maybe a broken vacuum line or sensor, or faulty wiring.

take the gas filter off, and blow through it, if it feels restricted, replace it.

95 chevy silverado v8 it starts and runs fine in park but it stalls out as soon as i pit it in gear.


The first thing i would do is check the fuel pressure it should be 9-13 psi with key on and engine off.If its not within these specs then first change the fuel filter and if pressure is still low replace fuel pump.Let me know what you have.

Did you notice if you where low on gas either or both times this happened? I wonder if it's not a fuel pressure problem? Other wise might give it a tune up air filter, plugs, fuel filter. I've also noticed that chevy's are always happier with a fresh oil change.

did you check the fuel pressure? there is a sharder valve on the fuel rail to do this. i know you have to have a certain amount of pressure in order for it to run.i think on fuel injection its around 60 to 70 psi.and on throtle body is around 30 to50.psi. i also know if you run your truck low on fuel alot it will burn up the pump gas is what keeps pump cool. also you said you found a pluged filter witch over time will burn up the pump. hope this helps.
