Got an issue with my Jeep TJ. It will crank but not start. I replaced crank and cam sensors. I checked the asd and fuel pump relays. I also checked the socket terminals for power where the relays plug in. Constant power terminal checks out good on both sockets....but when I turn the switch on to check power in the terminal sockets for the relays... one relay socket shows no power. Could this be a bad pcm? Any help would be appreciated.
