injector issue
hi all. this is my first time posting it maybe a little long..So 2 weeks ago i finally did the studs and head gasket on my 6.0 L all when smoothly finished and started driving the truck again. so I roughly pur 240km on the truck and I started getting a code # 6 injector not contributing so I firgure because it was -40c the fuel was gelling.. so I pulled over and turn the truck off erased the code started driving again that code when away then 10 mins after # 3 injector throw the same code. firgure I better go get some anti gelling additive put that in ran er for a hr then that code when away.. a day later took the truck again and noe # 2 injector throw the code plus low Voltage code. so now I though the ficm was toasted, so I had my buddy drop over with his laptop and we ran some test done all ficm test all passed 48v then ran injector test, all injector passed expect #2 it didn't fire on the 3 test we ran.. so I started thinking maybe the wire harnesses for the injectors. so I order one just to try and a new injector for #2..so just wondering if anyone has any other thoughts.. truck had full delete and bully dog tuner..
