I am at work and i started the car. It ran for 3 minutes and died. I went to restart it and both fuel pumps made no noise. I retried it 30 seconds later they both came on and it ran for 3 more minutes and died again. Any ideas?

 

you have 2 fuel pumps?

i would check the fuel pressure with a fuel pressure guage...
since you have 2 pumps you should have about 84 psi...

 

I added an external fuel pump for the supercharger but it only slightly increased the fuel pressure to what it should be stock. I always ran 3 or 4 psi lower before the addition. The idle is a little higher than normal and it has a slight vibration.

 

only thing i can think of right now is fuel pressure...

off topic sorta:
couldn't you just have put an adjustable fuel pressure regulator on it?
i thought the stock pump was good for like 125-155 psi?

 

The computer keeps the fuel pressure at a certain point. The purpose for the extra pump is so there is plenty of fuel coming when the boost hits. My fmu will cause the pressure to rise but under normal conditions i belive it is some where in the low 40's. I hit 58 when i get in the 5+ boost range. I thought if the internal or external pump was going out at least one would come on. Maybe the security or computer is seeing a signal cutting the fuel off. I have no idea what to do next. This has only happened 2 times ever. Both involved starting the car moving it 20 yards and waiting for it to warm up. I have no idea if this could have anything to do with it.

 

wow, ok i see... this might be above my head... not fimiliar with forced induction...
sorry i can't help...

 

How long before you can start the car back up? Is the motor warmed up?

 

Within 30 seconds. The car had been running for 2 or 3 minutes and then ran another 2 or 3 minutes the second time.
