PCM module in relation to fuel pump 93 Wagoneer

I hope someone can help me on my problem, my jeep quit and I noticed that I didn't hear the fuel pump come on during start up. I changed the pump and everything was fine for 6-days, It just quit again and I couldn't hear the pump again.I've done everything tha haynes manual said (1.fuses,2.relay, and 3.checked voltage at the pump connection)1.)the fuse was fine, 2.)relay checked out fine according to the book, 3.)there was no voltage at the pump connection. I put the relay back in and checked to make sure it clicked when the ignition was turned on it did. I checked the obd, and got a 12 and 55 which didn't help. My question to those more technically enhanched then me is can I test the pcm module without a scan tool. and is there anything else to check, barring buying a 450.00 part with the chance it's not the problem. any help is greatly appreciated.

Post this question again on the midwheel board. It doesn't belong here. It's only the old type cherokee and wagoneer discussed here.

Ask about the '94-'01 Ram 1500.

And last I checked, the '88 Jeeps were also "midsize board". [img]images/graemlins/blush.gif[/img] [img]images/graemlins/blush.gif[/img] [img]images/graemlins/blush.gif[/img]
