Hello,
I was wondering if someone could point me in the right direction. Customer called me in for a no start. Truck will not crank over. I first checked the basics. Battery and connections were good. All fuses good. Ignition switch seems ok. I noticed there's a relay right beside the starter. There's a yellow wire with a white chaser that I assume should receive voltage when the key is turned on but nothing. If I run a wire from there to battery positive the starter engages. I was reading that these trucks may of been equipped with a delay to protect the starter from getting damaged. Also, I noticed in the column that the wires coming off the keyswitch go to a printed circuit board and from there I'm not sure how they exit. Unfortunately, I don't have a wiring schematic which makes it a challenge.
Any assistance would be greatly appreciated.
Thanks,
Jay
