Hey folks I have been chasing this problem for a week now and I need some assistance. It's an 08 Ford F-250 we are doing a 06 common rail cummins swap on it and everything was going smooth (kinda scared me) until now I have no power to the starter relay and I've chased the wires and as far as I can tell I'm not getting power from pin 53 on the small pcm connector to the relay terminals. Is there anything in between there that can be blocking the signal. The fuse and relay are both good for the circuit. I can't take it to a shop because it's basically an alien now to a ford house. Any suggestions??

 

Interesting swap your doing
your post should be in the conversion section.
did you transfer the ecm and wiring harness from the dodge to the ford?

 

I did not know there was a conversion section here. I'll try to find it and post it on there too. Yes I have all of the harnesses hooked up correctly. It was starting fine for a while and I moved a few hoses to a better location and then it did this whole no key power stuff again. The first time it did it it was a blown fuse and now I have no idea. I checked all fuses and relays and they check out but I have no connection between the pcm and the starter relay terminals
