So after replacing timing chains on my truck I had all kinds of codes two blown fuses I have checked all connections I do have for broken pigtails 2 on injectors to an ignition coils 1 on the crankshaft sensor currently working on those just found out I have to blow fuses anybody might know why all
these was triggered
Bad connectors could have blown fuses . You didn't list any codes , Your info on your truck is wanting . Mileage etc . We don't farm your info we just use it to evaluate . Location hot /cold etc .
You should have lifted battery negative during timing job . The more we know the more we can help .
I do hate that we are so careful because of hackers etc .
With key on 12vdc is standing on injectors and cops , pcm pulses grd side .
