fuel pressure problems
ok so month back i was having very very hard starts and couldnt hold fuel pressure. was like that for ever but then i changed the fuel pump and that fixed everything, car stated right up every time for the better part of 4 months since. Now the past few days i started having hard starts again...wtf. also a less that perfect idle. A little low and slightly erratic at times.
I hear the pump prime just fine, pressure goes up and started to drop just like that. So i thought maybe the fuel pressure regulator went bad. pull that off (managed to snap a screw in half - ****) look at it and the diaphragm looks fine, no holes no nothing. either my check valve went again on the new pump after only maybe 5k miles. or what - leaking injector? The engine was rebuilt just over 30k ago. i would hope an injector would make it longer than that. Now i have been running a higher psi via an adj FPR but not much higher and only cause of the cam in the car.
any ideas?
