ECM failure

Hey Guys I wanted to throw this diagnosis out there to see if it makes sense. f250 diesel 140k. Started up after sitting 7 day in cold weather (lows below freezing, cold for FL) anyway zero power. Drove to ford dealer and they are throwing a $2500 repair at me. They indicate that i have a bad injector (electrical portion of the injector) that has shorted out the ecm. Does this sound right. It seems real fishy to me.

Thanks

what year/motor do you have?

personally I have never heard of that. I take it that you are out of warranty.

Thanks. It just doesn't sound right. He explained to me that power comes from battery and/or alternator to the ecm where it is changed from 12v to 50v and then powers the injectors. he stated that the short in the injector fried the ecm. He also said i need a pressure regulator.

I plugged my truck up (heater) for the first time during this cold snap. (I didn't even know that i had a plug til someone showed it to me). Is there anyway that could have caused something?????

I am not an expert on the 6.0..well none of them really. 6.0 injectors are fired by oil pressure so does not seem to me that electrical gets to the injectors.

Best to slip down the the 6.0 section and see what they say

Run away from that dealer as fast as possible. If the injector solenoid went bad, it didn't take out the ECM and shouldn't take out the FICM either.

How rough does the truck run? At this point, I'd also suspect weather you really have a bad injector solenoid.
