Where do i check it and supposibly mechanic checked wiring and it was fine but we feel he has scammed us for 900.00

Check the cam sensor connector for ground , i sent you the wiring diagram


The light brown wire should have ground on when you try to start it

Customer: replied 1 month ago.
I want to call you but i dont feel like i have gotten 28.00 worth of answers cuz we need this truck to haul our equipme
Expert:  Chad Farhat replied 1 month ago.

If sensor is replaced several times , you must have a wiring problem to it from the PCM side

what is the mileage on it

it seems to me they Misdiagnosed the problem and they are throwing parts at it hoping to fix it .

I would do proper troubleshooting, even if you had to pay a dealer for troubleshooting

usually the PCM is the problem but testing is needed to confirm .

they need to pin out the PCM make sure each pin is supplying power or ground to these engine sensors .

Please let me know if you need anything else on it, just reply back & we will continue

If you are good , kindly rate me.

A Positive rating is much appreciated

This post will stay open for you even after you rate me, for you to come back and ask any follow up question you may have on this issue

Thanks You
