This truck has the 4.0 4x4. I have been at this truck all day. It
started yesterday trying to track down why the rear brake lights don’t
light up but the high mount light does. So after looking at the wiring
diagram I found a wire piggy backed up to a relay (1 of 3) that are
the same relay so I swapped the relays around and nothing, I looked at
all the fuses one by one to see if one was blown because there was
water in one of the rear lights. And that is where I ended figuring I
would track it down today.
So I get in the truck to put it in my drive way and it won’t start.
Okay fine I look at all the fuses again and triple check all the
relays and swapped them back to original location but they are the
same relays still nothing.
I have now determined the fuel pump is not kicking on and has power
across all the main fuses and the truck is not getting spark either.
I have run a test light to the fuel shut off switch and it isn’t
getting power to it.
I have put in new relays nothing
I have tried a new pcm nothing
I even put a new TPS b/c I knew the one on the truck was going bad
I haven’t been able to find the control module to test it
Am I missing something here? Is there anything else that I have missed
or need to do? The ecm I put in was already flashed with the correct
calibration and I have reset the ecu after each part install still no
gas no fire. any help much appreciated
