My truck would not start and I replaced the fuel pump relay because it was the same problem I had a year ago. I tried to start it and it almost fired then nothing. The theft light was not blinking while starting as befor. What is wrong? I am stranded a block from my house thank goodness.

 

Same list as JAN-2011.

Fuel inertia switch, is it tripped.

Jumper fuel pump relay, do you hear it run ?
if not fuel pump fuse.

Try hitting the tank with a rubber mallet and try again.

This is the full list from before.

I had good luck last time when I replaced the relay. I tried again but maybe the new relay is no good. I will figure it out eventually. Thanks for the input.

 

It turns out that the fuel pump went out and I had to have it replaced. Oh well.
