ive recentley started having problems with my car starting it will crank and crank and not start then after about 2 mins of trying to start it will fire up and run fine it acts like not getting any fuel ive changed the fuel filter and the fuel pump relay but no change the car has a bbk apr on it set a 47 psi(no vacum) im stumped please someone help thanks

Have you tried checking the fuel pressure to make sure your getting that?

Agree with previous poster, should measure the fuel pressure after pump primes and at idle. There are a number of posts on the board about hard start issues. I'm sure others will chime in, but 47 psi sounds a little high for a stock-like setup. Does the pressure hold constant for a little while, if it doesn't the injectors might be leaking. Leaky injectors might flood the engine causing the hard start. I think ~42psi is the standard. You might ohm the injectors, ALL of them should be consistent and at least above ~14 ohm, if not they need to be replaced.

I had this same exact problem with my car many years ago. I had the computer swapped to a 730 pcm and the problem went away lol

i checked the fuel pressure today and it oly showing 22 when the pump primes and about 32 when its idling its getting harder and harder to start and im out of ideas thanks in advance for any help i can get

i forgot to mention it has a custom burned chip in it from harris performance i dont think that would cause me any problems though

I think 22psi/32psi is too low for our TPI cars. I checked mine the other day and got 42 and 38 respectively. I'm no expert, but I suppose it could be the fuel pump dying, or maybe the FPR went south?? Does the fuel pressure change when you adjust your FPR? I've also read about rubber lines in the tank falling apart over time and either collapsing or otherwise limiting flow. Otherwise could be restricted fuel filter, but you've changed that... so... hopefully others will have some good ideas. Good luck.

i adjusted the afpr and it didnt seem to change the pressure you think that may be the problem?

Seems suspicious to me. In the original post you said no vacuum, ...does that mean you don't have the vacuum line hooked up? I would try that and see if there is a difference. I don't have much else to suggest. Maybe there's a way to check the pressure without the regulator, but I don't know.

Put a fuel pressure gauge on it and prime it up. Clamp the return side of the fuel line (rubber line). Watch your pressure. If it bleeds down quickly, you have a bad pump. If not, pressure regulator is done. Do not run the car with the return line clamped.
