help! no bus on odometer , no crank, no start.
car wouldnt start today.. it snowed last night, only an inch or so.
jiggling main engine harness wires sometimes nets me a crank and start..
IF it starts rpms stick at 1000 and wont change when revved.
IF it starts the car turns itself off after 5 seconds.
i also get no temp sensors, no OBD plug functionality.
i tried another PCM and that nets me in a starting running car, but no odometer, no speedometer, no RPM changes (stuck at 1000)
it will shift into drive and move with alternate PCM.
im suspecting water leaked into a connection but cant find any corrosion on any connector. transmission harness looks good. manually applying 12v to the starter trigger nets me a cranking starter.
could my BCM have an issue since im not getting OBD2?
i think im extremely competent with these cars but im lost, any ideas?
