fuel pump

[jt1200r]

fuel pump stopped working. got a new one nothing. hot wired it ,it worked for 30 seconds and stopped. could the relay have been my problem to start with?is there any way to check the relay? now i have to drop the tank again (yuck) maybe get another pump. its a 87 r10 stepside. thanks

If it stopped it probably built up to pressure. Is it stopping with the engine running or not running?

 

[89Suburban]

I think your problem is somewhere else, if you turn on the key and the pump runs, builds pressure in the system, then stops, that is normal.

i ran a hot wire to the pump. it and the engine ran for 30 seconds than stopped. no sound of the pump working

my thoughts exactly

 

[89Suburban]

Did you change the fuel filter?

 

[89Suburban]

Maybe take the pressure line off the throttle body and clamp a hose on it running into a bucket and see how long the pump runs?

Jesus, they all come from the same place?

The tank is clean and the screen is on the pickup tube right?

Just so you know, you might want to spend the big bucks and just suck it up and go to the dealer for your fuel pump if you are indeed eating them up. I've heard this before that the ones you get from a discount auto parts just aren't worth a damn. Maybe try one from Napa. Napa usually carries good parts too. I believe it's the Delphi or AC/Delco pump you'll want.

I got my last delco at O'reillys...

Cool, I didn't know O'Reilly's carried the Delco brand. Obviously they realized the aftermarket brands were junk too. So there you go, I bet a Delco is much cheaper at O'R than the stealership.

i will use nothing but a delphi or ac delco in these trucks, since it is tbi the pump shouldn't be more than 60 dollars for a delphi, since i have to warranty them i am fussy in what i use
