My son is struggling to get his car running. 2008 93k miles. I feel bad he lost one of his jobs, and he's struggling to make a car payment on a car that's not running.
He was driving along up a slight incline about 50 miles an hour and the car died while driving. The car would not restart. He rolled off into a parking lot, and we had to have the car towed.
1) He poured some fuel in the intake it starts and runs for a few seconds. Problem is fuel not spark.
2) I swapped the fuel pump relay....no change
3) There's no fuel pressure, so he decided to swap the fuel pump....no change
4) During the troubleshooting he broke the fuel pump relay socket in the underhood fuse box while he was checking for power. He ended up having to buy another UHEC box at the junkyard. So he swapped the underhood fusebox(UHEC) which came with fuses and relays.....no change....so it's not the UHEC box
5) I eventually pulled the cover off the fuel pump relay, and manually pressed the relay into position. The fuel pump started working. Tried another relay...no change. We checked the old fuel pump, and that also worked. So it's not the fuse, pump or UHEC.
6) Checked the PCM fuse/other fuses. The car runs if you put gas in the intake.
So now we're stuck? Apparently the computer (PCM?) is not telling the fuel pump to start. Before he runs out and dumps some more money on a new PCM / Computer, are there other components which could be causing the computer to disable the fuel pump....like security? safety?
What do you think is causing this ???? He's pretty depressed over the whole thing....this GP is his baby. He wants to wire the fuel pump to his radio circuit, and I told him hell no.
