I am trying to help my 15 year old grandson put a truck together that someone else took apart. We seem to have got it all together in the right order but are not able to get any power to the fuel pump so that it will start. We went through the trouble shooting guide in a GM manual and got all the way down to where we don't get any power on wire 465 frrom the pcm. We tried another pcm with the same results. I checked for a ground with a ohm meter and everything seems fine. I am not sure what voltage and where I should be getting it going to the pcm. Any help or advice would be greatly appreciated.
