My son's truck won't start. Problem began with truck acting like it was running out of gas. Added gas and ran for another 10 miles and then quit. It would not start again at that point. Towed it home and it started but ran rough. Then would not start again. The fuel pump and filter were replaced and it still wouldn't start. Replaced the pump again because a fault code showed possible bad fuel pressure sensor but nothing else. Changed fuel pump again but still doesn't start. Have not done a pressure check, doing that next. Any other suggestions that could be the problem.

Hello, I'm Danny
Here is the information you requested. It's possible you may have a weak or failing fuel pump causing this hard-no start condition. I would suggest performing a fuel pressure test. Here is a tutorial showing how to perform a fuel pressure test.

The fuel pressure specification for your truck is to be 55-62 p.s.i.

If the fuel pressure is not within specifications you will have to drop the fuel tank to replace the in-tank fuel pump. Here is a tutorial showing how to replace an in-tank electric fuel pump.

I've attached picture steps below on how to remove and replace both the fuel pump and fuel tank on your Chevrolet truck. Hope this helps and thanks for using 2CarPros.
