I bought a 2001 GMC Jimmy about 3 weeks ago and I didnt fill the tank yet untill yesterday. It was the first time I filled her up and 45$ later, I got home and tried to start it again, and it didnt start. I let it sit for 15 minutes and went back out and it started up. I then pulled it into the garage and polished the headlights. I went to start it up when I was done and it hasnt fired up again. Im pretty sure its my fuel pump because I dont hear it running when I turn the key. I just thought it was weird that It died once I filled the tank. Could it have been the strain of the full tank? I just wanted to know if there was anything else I should check before I go about replacing the fuel pump. Thanks in advance

 

They rarely die when the tank is empty!

I would test fuel pressure to make sure that is the cause. As well as checking for proper power and ground at the pump.

 

awesome thanks alot, Il check it once this snow goes away.....
