I am currently having a problem with getting enough fuel to the engine in my silverado. At least this is what the code is reading. It has stalled out on me a few times (its an automatic). I have ran dry gas through the fuel and injection cleaner as well. Im not sure how you can tell if the fuel pump is going bad but it sounds fine to me. Anybody have any ideas??

 

Check the fuel pressure. In the fuel rail there is a fitting to plug in a fuel pressure gauge.

 

There is no code that says you are not getting enough fuel. If you have a lean code then it could be not enough fuel but it could also be to much un metered air.

 

I agree, sounds like unmetered air entering the engine. Check air intake for leaks/cracks. Then I would run a vacuum test, connect the gauge to the intake manifold. You should read between 18-21 with a steady needle. If reading is low, then you probably have a bad intake manifold gasket. Easy to change out, buy the Felpro(metal) gasket. Change out the knock sensors at the same time, and seal the the rubber knock sensor plugs against water. Hope this helps.

 

Turns out it was the intake gasket. Thanks for your help!

 

Thanks for taking the time to follow up on what the fix was:-)
