Hello all, I have an 88 pioneer and I swapped out the fuel pump yesterday since the old one had a baaaaad crack in the hard lines.
Well after my little swap I went to turn on the truck but to no surprise the new pump didnt prime, so come today I spent the entire good half of the evening testing out the relays and even looking at the ground cable.
I am not too well versed in trucks but am doing my best to learn, so far I have fixed a few problems on this truck and this forum has helped me out greatly without me needing to sign up, but now I am at a point where I am stumped.
The relays are good and the ground after a bit of cleaning up is mediocre at best, and yet no prime in the fuel pump. Any advice or steps I could take to try and make this truck run again?
I originally thought one of the wires on the fuel pump came undone when I was putting it in but that seems very unlikely. And when I plugged in the old fuel pump to the harness to see if IT would prime like it use too, it did nothing. But the float on it worked unlike the new one.
