Hello,
I have been watching some of the videos related to 5 volt reference at sensors.
So truck was turning on with some codes P302 (random misfire), also had some o2 heater ground faults for both upstream sensors.
After removing an aftermarket stereo and alarm car will crank but no start, also im measuring 12volts at TPS sensor,
I have tighten all the ground nuts i see, i pulled out a wiring diagram (not sue if it is correct for my truck) and it states a ground connector on left side of engine, havent been able to find that.
Checked all the fuses and only fuse that was blown is blower motor, replaced but same thing.
Any help would be greatly appreciated.
Thank you
