FICM Failure?

[CurlyDE]

This morning my 2004 decided to stop running properly. On cold start (as cold as it can be in SC this time of year), the truck was not idling well. I left the truck at home for the day as a result. This afternoon, I pulled the codes with AE and got low voltage DTCs for all injectors. I ran the KOEO and injector buzz tests, both of which resulted in low voltage codes for 5 of the injectors.

The truck fired up properly at this point, but the FICM main power voltage dropped to 40v and stayed there while running. From what I have read, anything less than 47-48v implies that the FICM is faulty ... is this accurate? Should I pull the FICM and have it repaired at this point?

Thanks,
Don

yes. do not put another ficm in until you load test the batteries.

Any auto store can test the batteries, right? My records indicate that I replaced both batteries in October of 2009.

Any recommendations on who I should send the FICM to for repair? I was leaning towards ficmrepair.com (based on a few reviews).

yes, most auto stores. Make sure you pull them out and do them seperately. Right about Ed@ficmrepair.com. If you dont have a monitor, get one. Good luck.
