Sudden Crank/No Start condition - also no accessories in On/Run?
Hey folks. I joined because all my internet searches lead me to here. I have a 1988 XJ with Renix 4.0 and the AW4.
So the Friday before last, I parked my Jeep after work like usual. Got into it Monday morning, and it would crank but not start. I also noticed that I had no power at the accessories - my 12v cig outlet, blower motor, turn signals, and everything else I would usually have in "On" position are dead.
First I thought it was an ignition switch or dead spot in my ignition cylinder. Changing those did nothing. Then I moved on to the ignition coil, then CPS. Still nothing. I have fuel pressure, and my CPS reads the correct resistance but no voltage (0.0v) when cranking. I cleaned my grounds and C101 thoroughly, and Im still getting no change. Ive also checked my fuses and swapped relays around and theres no difference.
Is there something Im missing here? The thing that really stands out to me is that I have no accessories. Turning the key just goes from nothing to straight cranking, but no fire. Ive read that the Starter Relay Solenoid behind the battery supplies power to a lot of different things - could this be the issue?
Ive got the ignition switch dropped down off the column, and moving it with a screwdriver I can read 12v by probing everything, but Ive got nothing else as far as functions.
Am I way off base or missing something here? Any guidance would be appreciated.
