Well efi has been a learing curve but none the less im getting the hang of it .
I went to leave for work today and my truck wouldnt start put stock tune in and cleared codes started and drove fine. Got to work and tried to start 20 min later would not start ,tried though the nite and started every time ! Left work and truck dies on road cleared code U0105 started right up . WTF ? I belive i still have engine coverage because in under 100k and 5 years should i take it to the dealer ? What to look for ? Code is for loss of com to FICM,
Please help .

Not sure but maybe the wire harness has rubbed through

I would take it to GM and get them to fix it,there where a lot of issues with the harness.....its prevented by installing a rubber chunk of hose under the bracket

If your wires have rubbed through then i would want them to fix it if they arent going to charge you
