Have the dreaded P2146 P0201 P0204 P0206 P0207 codes. Tractor mode. Ice picked all of those injector connectors. Replaced #7 pigtail. Exposed all the wires from FICM until the the loom goes into the plastic cover on top of engine. No frays, chaffing, etc....
Dealer said it was a bad FICM. They wanted my unborn child for it though.
Anyone know of a REPUTABLE place to get the FICM tested/repaired or purchase for a reasonable price? Dealer wanted 3K for just the FICM.
You might try surfing eBay, checking with local auto parts stores for a reman or inquire about a rebuild service.
You can also search one of the GM parts websites like GMpartsgiant.com to look up the part number and then you can use Google to search for sources using the part number or you can try the Partsvoice website to see if any Dealers may have one collecting dust on a parts shelf somewhere
I started this thread on the Duramax Forum but I wanted to post it here to help anyone else that has similar problems, and more importantly, post up the FIX!!! I've sifted through so many dead or ghosted threads that never had the solution posted up...
