I bought a roller truck its a 03 gmc single cab
Well I put a 07 classic engine on the truck
Well the problem is when we turning on there is no spark to the coils and truck don't turn on
Already took care of the pcm stuff the vatts,changed crank sensor 3 times,checked fuses and grounds,
We used a snap-on computer to check codes and the theft deferrent came up?
Can anyone help?
I I wanna get this puppy rolling already

 

Vehicle anti theft system right? If you have a tuning software you can disable it I believe. Sounds to me like the system has been triggered and cut the ignition

 

Is this truck a standard? U should be able to set the vats to none in the computer and be ok. If ur just trying the relearn process that others try it don't always work and actually have to go in and turn vats off.

 

Already took off the vatts I just yesterday again to my tuner

 

i al ready fixed this problem thanks anyway guys
