I have a 93 Grand Cherokee I bought it the lady said someone stole the radio out of it which was not the orignal radio the headlights flash the security light flashes and the fuel pump doesn't run I tryed the key door lock trick and it didn't work if anyone has any clue I would very much appreciate it btw it still doesn't have radio in it

do a search, it's all over this board. I knew how to fix it a week before i bought mine. You need to ground the factory disarm wire.

Best to disable it, the factory system has a nasty habit of causing issues at the worst times.
