2012 pete's did not come with an 870 engine... just trying to get a clearer picture of what you have.

Is this a glider truck? ... What is the engine serial number (ESN#)?

(referring to the engine side of things)...

btw: changing egr-related engine sensors will not make it refuse to crank.

Also, if there is a bad sensors or bad connections after replacing things, there will be check engine lights. You can use insite software on it to see what the cummins codes are.

Thanks for the reply Rawze. The serial number is 727U7471. I thought it was an 870 due to it having the EGR on the passengers side. I didnt think changing them would effect the engine to the point of not turning over, but I am new to the ISX world.
