I have a 2004 F-250 with the famous 6.0 power stroke. The truck has 80,000 miles on it and I have not had a problem until now. I am getting codes for all cylinders having a low voltage for all fuel injectors. Any ideas? Could it be a bad contoller or could it be a weak batteries set up? I have two ultima batteries installed. Any feedback would greatly appericated it. Have a good day.

 

hi, not a big fan of the 6.0l engine -but have worked on a few and with your concern the repair always called for a new idm/ecm modulei would get a diagnostic tool tests run buy someone who really knows the 6.0l though because it is an exspensive repair.

 

Well within the warranty limits as well...

 

Thanks to all that helped. The FICM (Fuel Injection Control Module) was bad. Ordered rebuilt one and turned into Ford to reprogram. It is covered under warranty. My truck was out of warranty and it ran 250 for labor and 700 for parts. All in all it was not a bad fix. If anyone out there runs into this and orders one on line just a word of advice. The FICM does not come pre programmed. Leave old one installed and turn into Ford to have old FICM downloaded and reloaded onto new FICM. Thanks again.
