Go ahead and take a second look. I'll bet you Stinger's right. I thought that there was something fuel related beneath the drivers seat, but that may be the fuel pressure regulator, or I may be completely off.
If it looks like a relay,then look under the drivers seat. You also should have a similar looking realay in the kick panel on the passenger side right above the the computer.
You sure you didn't trip the fuel cut off switch? That is in the hatch under the stop for the hatch latch.
Stinger is correct, the part you got is wrong, if you drill the rivets out of the ICRM box on the inner fender you will find 3 relay switches if memory serves. The fuel pump relay is the square(cube)one. IT IS SOLDERED IN! And I'm pretty sure it has 3 blades(could be wrong on this point, I havent looked at it in months).
I think my relay is also going out.The car starts and runs fine but it is starting to cut off after running awhile now and act's like it is out of fuel.Then if you let the car sit for 10 or 15 minutes it starts and runs just fine again like nothing happened.This problem has always happened on a warm Texas day.At night time no problems from the car at all.I have a 91 v8 donor car will the part innerchange between my 93 4 banger?
