[QUOTE="rattle_snake, post: 16745947, member: 126699"] Plugged in the alternate FPDM and problem still exists. Ran for 10 min then died and doesn't want to restart. fuel pump primes but reads no fuel pressure. Re-checked BAP power when in failure condition the BAP output is solid at 17 v. Fuel pump voltage and pressure are erratic if it starts. I'm assuming that the problem is related fuel control loop, so that leaves only 2 other things, FPS and ECU. I installed a mechanical fuel pressure gauge on fuel rail and then couldn't get car to exhibit problem. pressure was consistent on mech gauge and reading over OBD. Given this is a diagram type analog sensor, I wouldn't expect erratic behavior. Reading FPS type threads, I see some about failures after hitting rev limiter. I had floor mat get stuck under gas pedal and hit limiter on 1-2 shift, I shut off engine quickly. Car ran fine for awhile after this event. No fuel is leaking out of FPS boost ref line. Perhaps related?? Throw a new sensor at it? [/QUOTE]
