I went to start my car yesterday (97 LSC, 93K, about 50 degrees out), and it would crank, but not start or sputter at all. To me it sounded like it wasnt even trying to fire off. So first thing I think is crankshaft position sensor, camshaft position sensor or possibly a bad fuel pump. The car was at ambient outside temp when I tried to start it. No anti-theft issues.
Today I went outside to see if there were any key-on, engine-off DTC codes (used autoenginuity software). There were none. I then tried to start it again - same results. I then tried to start it with the accel pedal at WOT. It DID sputter to life after some cranking. Once running it ran and idled fine. I drove it for about 25 minutes to get the battery charged back up good and also to see if anything interesting would show up on the OBD-II software. No codes, all sensor outputs (TPS, O2, ECT, ect) looked fine.
With the engine still running I attached a fuel pressure gauge. I had 32psi at idle, and it would spike up a bit When I would tip on the throttle.
The car is pretty much stock (has JW dyno tune, gears, exhaust) and is in great tune (plugs, COP boots, ect all newish)
Thoughts? Fuel pump problem? Cam/crank pos sensor issue?
Thanks,
Cal
