90 was stalling, now no start
Went for drive two months ago , it started back firing then shut off, restarted, ran like crap, then ran fine. (No codes) Now sitting in shop I turn the key to on my radiator fans come on. I cane hear a relay clicking under the dash. I pulled fuses, seems to be in AC but still hear relay noise ( compressor clutch ) Sometime stops then starts an runs fine. Snap On says security problem. Replaced coolant sensor. Checked all fan wiring, still no luck I have FSM not much help why the fans are running....any idea??? thanks Ziggy

My fans both kick on when I jumper ether ALDL connector to read codes. Maybe your ECM is stuck in diagnostic mode....
Also the security will disable the starter via relay when activated I think so that may be the noise...
