ok i got a 2.3 weel of course this is the place for this.
no command from pcm to activate fuel pump after initial time out, fuel can be over ridden by jumping the DLC to ground. and truck seems to run fine.
no communication with pcm via scanner.
not shure what else is inop.

verified voltage on pins 1, 37, and 57
ohmed wires for grounds with DVM within spec
