OK I have a 1993 ZJ this is what its doing. I get in it turn the key and nothing happens the dash lights come on but the fuel pump doesn't I wait about five Min's once the engine and security lights come on it fires right up. the fuel pump and fuel relays have been changed. Is this the ECU if not what else could it be? I have been driving it like this I am just not sure where to go with this. Please help! It has all the bells and whistles its a in line 6 all leather power everything.
