I've already done that. :-/ I've tried the A/C and the horn relay in place of the fuel pump relay. Last night, I removed the wiring harness from the trunk area that supplies power/etc to the fuel pump and put my volt meter on that. I'm getting the 5 VDC for the pump. Yet, it is not turning on. Maybe I loosened the connectors trying to put the tank back up. I don't know.Originally Posted by Fivefingerdeathpunch

5VDC? Shouldn't the pump run at 12 or better?

OK. Here's the latest. I found the wire harness that went to the pump harness from inside the car and could not read any voltage more than 5 VDC. But, as J57ltr stated, I found out that the pump needs 12 VDC to run and the two wires with the 5VDC are for the fuel level sensor/float. After beating a 14 gauge copper wire flat I re-tested the voltage I was getting at the fuel pump relay, unplugging the relay of course. I had nearly 15VDC at the relay! So I began thinking again, bad relay. I bypassed the relay by jumping pins 30 and 87 and immediately the fuel pump kicked on! I started the car and it ran fine. I removed the jumper and replaced the fuel pump relay. But noticed that the relay does plug in or sit as tightly as the other fuses and relays in the box. After further inspection, The four receiver pins, IN THE BOX, are too worn to hold the relay properly. Junction boxes are not cheap. And they're not readily available nearby either.
Anybody have experience jerry-rigging a junction box to work again? Or moving a fuel pump switch/bypass to the interior of the car so that one may turn the pump on and off without popping the hood each time? LOL
