I put in a new fuel pump, but the pump is not working.


Asked by May 04, 2015 at 12:53 AM about the 1994 Nissan Pickup

Question type: Maintenance & Repair

After putting the pump in the tank, and the tank in the truck, pump does not work.
Checked fuse and relay, event checked power at the harness. Removed the tank and
new pump and directly connected the pump to the battery- nothing. Would this accurately
test the pump, direct 12 v to the positive and negative post on the pump? There was only
a slight spark when touching the post, butno noise or vibration. I'm finding it hard to
believe it could be completely defective?

I wouldn't just because a part is new doesn't mean that it is a good one, this stuff is mass produced and the quality controls just aren't there, I have always tested before installing in my shop, saves having to pull it again and it also primes the pump when you do get it in.
