Recently my truck just died in the middle of the road. The check engine light came on, and the "wait to start" light stays on for a second, then goes out. I did a load test on the batteries and found that I had a faulty, (shorted), battery, so I put a new one in. After having the batteries disconnected, it starts right up, and everything appears normal, runs for around ten seconds, then dies. It won't restart until I disconnect the batteries again. Then it starts right up again. I get no codes on my scanner, just a note that says unable to link to PCM. I'm thinking relay or fuse, but none are blown. Any help would be appreciated, thanx

 

welcome to fte, you'd get alot more answers if you scroll down on the forum page to either the superduty or the 7.3 diesel section

 

Thanx, I'll give it a shot
