Jeep starts but shuts off.
I replaced the batt in my 94 GC and now it won't stay running and the security light flashes how can I fix it?
unhook the neg side of battery for about 5 minutes so the computer can reset itself,if this dont do it ,look in fusebox and pull the ECM fuse for same amount of time,replace.this should fix your problem.
Computer must relearn. Have you scanned the computer for trouble codes?
I know on some Chryslers you just had to lock and unlock the door with the key to disable the security system. You should give that a try.
take ur ignition key to the passenger door turn to lock then unlock and that will reset ur computer
change the alternater
take your key and turn the drivers side door lock to the right , then left and then right again ...this will reset the security system.
2002 Grand Cherokee. Here's what happened to me: At every start, the engine would run for ~3 seconds, then die. Here's the solution: Use only a Jeep key made by Jeep. Analysis: I was using spare key (made at local auto parts store). It appears the official jeep key enables the security system when you insert it into the 'key hole'. Notes: If you see an intermittent problem like this, consider getting OEM (original equip. mfg., i.s, jeep) key.
BTW, intermitent problem indicates key is wearing out.
What worked for my 1994 Jeep GC was the key ticket(unlock, lock and unlock) in the rear door (tail gate) and then open the door.
