just installed a 02 pcm from tsp the truck turns over but will not fire. what do you suggest? anyone ever encounterd this before??

 

Did you receive it already, dam I thought it wouldn't get there till tomorrow.

Have you done the security relearn?

Procedures:

Crank engine, let it die and leave key on. The security light should blink. Wait till it stops blinkins (takes about 10 mins).
Try starting again, engine should die. Wait another 10 min till security light stops blinking.
Try starting again, do above step again.
This time it should start when you try it.


Do a search about security relearn and you should fine the whole procedure but that is the basic of it.

 

thanks dude your a life saver it worked its alive. ill keep ya posted as i get more miles on it

 

Sweet, enjoy it and let me know how you like it. Remember it may take some time before it really kicks in, or at least it took my truck about 100 miles before I felt the power.
