There was no previous indication of any problem....went to start the car yesterday morning and it would just turn over but not fire...checked fuses, all ok....fuel pump inside gas tank is brand new and lots of pressure in the fuel lines. Cranked it over a few more times, nothing... waited five minutes. Tried again and it started, and ran great all day with no indication of any problems, so warm/hot starting is not a problem.

I put in a new ignition coil this morning and turned her over...wouldn't fire...kept trying and nothing. Eventually took the airbox out and cleaned the crank position sensor...tried a few more times, finally on the third try she fires up, and runs great all day starting up fine even after sitting for 4-5 hrs as long as the engine is even a little warm, and I should say it starts without hesitation on both days as long as the engine is even slightly warm.

Any ideas? My parts guy thinks crank or cam position sensor...I'm baffled.

Everything is new, spark plugs, wires, cap, rotor, and now coil.
