I have replaced the Stater, solenoid, ECG ( computer) and the battery. I got nothing.. Battery drains almost instantly, positive terminal gets hot. I have used ford recommended parts. Work truck needs to get me to work wife's going to kill me if i keep trashing the interior of her jeep. Please help.

 

All I could GUESS from that information is you have the wires on the solenoid hooked up wrong. The cable that comes from the positive battery post goes on one of the large terminals on the solenoid ALONG WITH all the other wires with the large eye, EXCEPT the large cable that goes to the starter. That large cable that goes to the starter goes on the other large terminal on the solenoid ALL BY ITSELF.

If the problem isn't there, I would guess you must have some battery cables hooked wrong somewhere.
