Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I'm here to help get your problem solved.
What size engine do you have?
Since fuel pump sounds different I suspect a problem with the fuel pump. A quick test is to see if it runs on starting fluid, if so you know problem is fuel related. Next step is a fuel pressure test, fuel pressure should be at least 55 psi key on engine off, if low replace the pump. Let me know how it goes or if you have more questions. Thanks.
Here are replacement instructions.
No problem, let me know if you need anything. Thanks again and have a great day!
