Hey everyone, I have a 1998 V6 that's been having similar problems for a while now. I've replaced an O2 sensor, two relays gone bad, and the MAF sensor in hopes of fixing the problem, and a lot of cash later the problem still persists. When I turn the key to the on position without cranking the engine I can hear the pump coming on right away, the car will just crank and sorta sputter and shake but still turns on every time. All the fuses seem to be in good working order. A mechanic at Pepboys diagnosed it and told me it was the air/smog pump, but from this thread i'm starting to think it might be the crank sensor. Any help and advice will be greatly appreciated, thanks!
