Re: fuel pump problem?
 

ok so i changed the fpr.. and the car ran and drove perfect.. for a couple rippers.. couple burn outs.. then it acted up again.. i put my old fpr back on and it was fine again for a couple rippers and a drive arround the block then it acted up again...

if i release the pressure in the fuel lines then tighten the fpr back up it will run and drive fine for like 2 minutes..

so im guessing a problem with the fuel return line??? lol

or did i change out my fpr with another bad one? i got it from the junkyard..

Re: fuel pump problem?
 

throw a 20$ vatozone fuel pressure gage on there and see what the pressure is doing during those 2 minutes.

have you replaced your fuel filter ever?

does your fpr have a proper vac line to it?

Did it always do this? Have you checked where the fuel line meets the rail?
-when I swapped out a blown ls for a b16 I used the stock ls fuel line. I fucked 2 things up a) I had the banjo bolt on upside down and it is not designed to go on that way b) I accidentally swapped the top and bottom washers.

That basically casued a huge restriction in the line and it fucked my flow up. Car idled fine but leaned out and fell on it's face under any load.

i have no idea what i did wrong but i just unplugged and replugged a bunch of vac lines today and the car runs and drives fine for the most part :X

now to get my iab's wired up, get the motorcycle battery on (still dont know if i wanna do this or not) then ill be 100% done :X

problem is back :-X

Re: fuel pump problem?
 

Sounds like the car is fine if you let it cool for a moment, then acts up when hot. Electrical problems (bad or corroded connections) manifest like that.

commutator in fuel pump shot?

Re: fuel pump problem?
 

now the problem wont go away.. its not even about cooling down.. literilly 2 seconds it takes to unscrew the dampner to relieve pressure

apparently im a dumb ass and thought the dampner was the fpr..

anyways.. if i unplug the vac line to the fpr no changes in the car whatsoever.

is there a ground for the fuel pump itself... i redid all the grounds..
