i just put a 6.0 into a 05 crew cab 4x4. its a used motor reman from jasper has about 45k miles on it. We swapped out all the sensors with the 05 sensor now the truck is turning over but isnt firing going to retrace everything but just wondering if anyone had any problems like this before

 

Put your old sensors back in that motor could of had bad sensors...so just try and put old ones an retry

 

Make sure the ground is connected at the back of the block behind the heads near the fire wall. It's usually pretty common for causing a no start after an engine swap.

 

That to..
