PCM location

Hello,

The PCM is located up by the left front frame rail enclosed in a cover. Here are the instructions for the replacement and location in the diagrams below. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Not getin power to fuelpump I changed the rellay in all the fuses. Was good steal no power to pump

do you have power at the relay?? I would harder there first and check wiring before going expensive.

Yes I have power at the relay I checked the with a test light n I'm not gerontology no spark I changed the crank sensor to

crank sensor has no effect on the fuel pump, just injectors.

did you jump the relay to verify the pump works???? you jump the power wire to the gray wire. that should power up the pump. if it does, it is a control issue with the pcm. if it does not, then you have a wiring issue.



Roy

when I jump the relay to thr pump steal no power but when I jump it from the battie it turns on in I get gas n the rheal but when I crank the truck it turn but no fire or spark

so do u think i need to change the pcm

if you jumped the relay and nothing, then you have a wiring issue.

when you sent 12 volts to the pump, it worked. where did you run the wire?? battery to where??
