So after a 45 minute drive to the race track I turn the car off and go through tech inspection. When I go to turn it back on, it sputters to a stop. Still have full battery power and it seemed to want to start. Finally get a push to the pits from an ATV. After tinkering with it for ten minutes, it fires back up. I didn't make any major changes when in the pits though.
Decide to go home rather than die halfway down the drag strip and be "that guy" causing delays. Car makes the return trip home with no problems.
Later that evening, I go for another drive, but this time I'm logging with ECMlink. After about 30 minutes of driving and a spirited run up a hill, I pull off the highway. From 45mph the car sputters to a stop again. Wait five minutes, starts back up. Drive another mile, and once again, the car dies.
I waited another ten minutes and the car starts. The car makes the 30 minute drive home just fine with no more problems.
Like I said above, I have a data log from when it died. It's right about at 1,630 seconds when the car rolled to a stop. The only thing that jumps out to my inexperienced eyes is the WB reads lean at right about the death mark.
Is this a dying fuel pump? Or maybe an inconsistent signal to the pump, and possibly the ECU? Am I reading things right?
Car is a 92 AWD 1g. The car's had the below setup for months now with no problems. The only major change recently is new u-joints and t-case fluid.
Applicable Mods:
FIC 1050 injectors
Forced Performance fuel pump (not rewired)
Fuellab AFPR
ECMlink
Speed Density
MHI Small 16g (12psi)
