Hi, I have a 90 k-5 and I just put a new fuel pump in it. Now it will not start at all. She cranks but I am getting no fuel at the TBI. Does anybody know where I can find the fuel pump relay? I think everything went back in correctly and I would like to check the relay before I drop the tank again. Thanks guys.

How hard was it to drop the tank?

 

It really wasn't that bad. I will tell you, drop the hitch and take the bumper off first. It will make your life much easier. when you re-install the tank, check the fuel pump connection on the frame rail to make sure it doesn't come unplugged. You can't see it from install point and it will make your life hell. lol

 

Thanks for the help. I didn't have to pull off my bumper, but did have to take off the gap filler plate between bumper and tailgate. Got the skid plate bolts off i needed then the tank strap bolts and neck. My fuel pump fired the truck right up. first time i've heard it run more than five seconds. drove it down the road, needs some tlc but seems to be a good running truck. Did you figure out your problem?
