any idea why my pcm would tell my mil light to say security and put a dtc that says pcm,iac,anti theft and crank shaft poisition sensor not learned codes to appear and my programmer will only erase the pcm,iac code and will not let my truck crank it will start and shut off but if i remove the key for 10 seconds it will crank and run but later do it all over again ive had this problem since i returned it to diablo sport because of the programmer saying x modem timed out when trying to program the pcm

 

still sounds like a predator isssue to me. Maybe they gave you the wrong one or flash the wrong load into it. I would see about sending it back again.

 

02gmc, are you going thru James? Great guy. NEway, I was getting a xmodem timeout when trying to download from PC to Predator, but it was a comm error. I would send it to James and have him set you up.

pm me if you need his addie.
