All:
I had a crazy fuel delivery issue the other day and it left me stranded after sputtering to a stop. No crank. I got a EKP relay ground fault. Replaced the relay with a new one. Still same no start condition. Eventually it will crank if I start it hard enough.
Measured the pressure at the regulator, and it was zero. Activated pump with INPA and it goes to 70. Then it drops to zero pretty quickly after I stop that job. Get in to crank. Car is turning over the first time, and the pressure goes to maybe 30. Crank again, I get to 50. If I catch the third crank before pressure drops too much, I get all the way up to 60-70 and the car cranks.
I replaced the pump and filter about 8-9 months ago because the car kept turning off. Seemed to do the trick. No more shutdowns when driving slowly. I used a Hella pump from Bimmerworld. Could the check valve go bad that quickly? I’ve only put a couple thousand miles on the car since I replaced it. What should I do next?
Thanks!!
