hey everyone, i’m in need of some help .i have a s13 with a stock red top in it and for some odd reason it recently decided to be a pain in the ass, problem: when its cold it has a bit of a problem starting . once the car starts it runs fine for about 5 min. but after that it starts to cut out around 5grand , ??? any ideas? only recent things are a new fuel filter and walbro fuel pump.forgot to mention car doesn’t start after its been runing.
Pump is bad.
i’m not to sure on that because when it first runs for about 5 min it runs real strong.unless the pump could die out?is that possible.
could still be a bad pump. pump gets hot, pump shuts off.
Check fuel pump relay as well.
Keep a fuel pressure gauge on it the entire time. Spark tester too.
thanks for the quick responses guys. very much appraited
