b18c dies with gas
So here is the story. 98 b18c p72 ecu. New fuel filter, new fuel rail, new fuel pressure regulator.
So I turn the key. Pump primes. Good. Turn it to start. Engine cranks. Good. Engine Starts but is sputtering. Not Good. Then engine dies. Sometimes the engine will start, rev to about 2k then dive down and die. If i am pumping the brake pedal. (The brake pedal goes to the floor because I have not bled the brakes yet) Then the car will try to idel at about 1000-700. but eventually die. if I hit the gas during any of this time the car will not even start and will die if I had it almost going.
Any ideas. I am confused at this point.

Re: b18c dies with gas
Have you adjusted your FPR? The pressure may not be high enough. You have to look at it as the car was running fine before you made the last changes, so look at everything you just did. Hope that helps.
Edit:Just looked at the build page, whenever you are running an aftermarket adjustable FPR it is wise to use a fuel pressure gauge alongside to keep tabs.

test your battery and your alternator, this happened to my last car, the alternator was bad and caused the same symptoms we thought it was a fuel pump, but three batteries and an alternator later the problem was fixed

I have a fuel pressure gauge arriving tomorrow. it just wasnt here yet but thanks for the reminder that it is probably off.
Engine never even has time to get warm obviously. Main Relay is doing what it should... Oil pressure around 40 at idle dips obviously when it is dying. Oil doesnt look milky or anything. I am confused but I want to know more about the alternator maybe causing this. How the hell.?

***update***
I put the gauge on this morning. The car started up as soon as I put it on, I adjusted it to 50 psi and it ran fine. No idea what is wrong with the stupid thing haha. It is nasty and rainy out today. I will hopefully get some help this afternoon and I can bleed the brakes and go for a real test drive. until then here is to hoping it stays running!

Nope, car is not fine. I found the issue though. I was waiting for it to die again. This just proves that lots of gauges make for much easier diagnostics lol.
Car decided not to run well. Fuel pressure was not even registering... So now I am going to pull the fuel pump... See whats up.
