I have a 2003 chevy avalanche and recently replaced the fuel pump and now it won't start itll start if I spray starter fluid in it but can't get it to turn over on its own Mechanic's Assistant: Have you ever replaced the fuel pump, or is this the original? This is the first time just took the original out Mechanic's Assistant: What is the model of your '03 Chevy? 1500 Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far? Everything down to the fuel pressure regulator sensors etc Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Haven't tried the relay

Hello, my name is \*\*\*\*\* \*\*\*\*\* to just answer! I will be assisting you with all of your vehicle questions today. I’m really sorry that you’re having this issue and I’m going to help you through it, but please understand that I (respectfully) don't know your skill level or tools you have to assist us to diagnose/repair your vehicle. Also, understand that I can't see, smell, hear or touch the vehicle either, so your patience/understanding is appreciated.

The site will prompt you for a phone call. **Ignore the pop-ups.** I will let you know if one is needed. Thank you. if you turn the key on can you hear the fuel pump running for a few seconds?
