ignition issue. HELP!!!
I have done a bunch of troubleshooting. Here is some history and steps ive done so far on my 99 cherokee.
around a month ago, my gauges would all drop out and check engine and air bag light would turn on. this would happen intermitenly like a broken wire or loose connection. off and on
Recently as im driving, my ignition to the engine would cut in and out. The only gauge that would drop out is the tach. even though im still rolling in gear it has no read out. intermitten as before with all the gauges
I assumed it was my key cylinder but i have tested that both of my ignition wires, both power wires, and acc. have power at all times. I test that my distriputer and coil dont have power when its not working.
That led me to believe it was the pcm. I have access to all data and verified the pcm has full power at all times.
any more ideas for troubleshooting?

what do you mean the ignition cuts out? can you describe that a bit more? as for the gauges, id check behind the dash. there might be a gremlin in there. does horn work? could be clock spring, but idk.. refresh grounds. have you put it on a code reader?

no codes stored. by ignition cutting out i mean nothing is firing and i roll to a stop. all the electrical works except for tach dropping out and no cylinder fire.
