i did both i put it on the mark and felt the piston come up with a piece of rigid wire but you have me thinking about the PCM. i heard the motor run before i pulled it and swapped it, and when i did set the cam sensor it falls in on the right position making me think the timing is good. do you think it could possibly be the crank sensor on the transmission bell housing too close? someone told me it usually comes with a tab at the end that tears off once the torque converter is in motion ???? i really appreciate your help kurt
