1994 Ford F250 V8 Four Wheel Drive Manual 198000 miles
Hi, I have a '94 f-250 with a 7.3l powerstroke diesel. The truck had been hard to start ( glow plug lite comes on and goes of after a few seconds) requiring long cranks before it would fire up. Once it firede up it would run down the road with no problems. After awhile of it starting like this, it seemed every so often that it would have a miss. If you then stopped, turned the truck off and started it again it would run smooth with no miss. It ran this way for about 3 weeks when one morning I get in and start it (long cranking then started and ran fine) and get about a mile down the road and the truck steadily lost power and died, coming to a rolling stop. I try to start it. Cranks and cranks and will not fire.
I was able to get a shop to come to my house and put a handheld diagnostic reader on to try and find a fault code. The technician said that his reader used the power coming thru the ECM to power itself up, but he could not get his reader to come on. He said that most likly the ECM had gone bad.
Before I had them come out, I fully charged both batterries and cleaned ALL contact points both positive and negative. Everything electrical still works on the truck, it just wont fire and run.
I have heard of a EEC module or relay that is suppossed to provide power for theECM. Do you have any idea on what my problem could be? I am pretty sharp on gasoline engines, but this is my first diesel ( and a powerstroke at that, wich I am told is different than other diesels) and I am lost.
