Fuel pump not working...

By teal_dx
- Mon Jun 04, 2007 12:11 am #9620 So I had my EG all put back together ready for the photoshoot, and the last thing to do was start it. I put in fresh gas, and the fuel pump is not working at all. Everything is wired up, and I checked the 15 amp fuse in the back left corner of the underhood fuse box and it's OK. The pump is not priming at all, no whine when I click the key forward. I took the fuel line off before the fuel rail just to check and it's bone dry.
Any ideas on what to check? I'm going back to work on it Tuesday.

- Mon Jun 04, 2007 3:13 am #9624 I've been thinking about this all night, Everything worked fine a year and a half ago. A year and a half later it doesn't work... I wouldn't think the main relay would go bad from just sitting. So I'm going to check out the wiring.
I read on H-T that you can run + and - wires from the battery and if the pump primes, then the relay is probably bad. If it doesn't prime, then the pump is dead.

- Tue Jun 05, 2007 11:29 pm #9924 well, good news is that the pump works. I ran a pos and neg from the battery and touched the pump terminals and it worked perfect... Now I'm trying to find the fuel pump relay. I was told it is under the dash near the steering column, but there's not much there besides the main fuse box. there is a small grey box with a brown connector going into it behind the hood release lever... Could that be it? there is probably 8-10 wires in the connector...

- Tue Jun 05, 2007 11:42 pm #9929 Ok, so when I turn the key to the start position (the last click before it turns the starter on) The main relay was making a click sound as soon as my key clicked into the last position. then about 2-3 seconds later, the relay would click again, a little bit louder than the first click.

I don't remember it ever doing that before I ripped the car apart... Sound like a bad relay to anyone else?

Scroll to the bottom for our years. :thumb:



thanks!
from that link, I found this: http://s90858418.onlinehome.us/techauto/mainrelay.php

every single solder on my relay is a "dry" solder, the ones that tend to go bad. :lol:

- Wed Jun 06, 2007 1:41 pm #9993 I tried to remove and re-do the solders like the link showed, but it did the same thing. I guess the relay was done.
But at least I learned how to solder on a circuit board...

Here's a close up of the relay, it's about the size of a big pack of gum. You can see I used a sucker thingy to remove the old solders before I put new ones down. But it still didn't work... Dealer has a relay in stock for $52. I'm going to go pick it up soon. :woot:
