Question about Cars & Trucks
There really isn\'t an auto shut down (ASD) relay. That\'s really a Chrysler thing. In any case there is a main relay that is for power supply called an EEC relay. I have marked its location in the top picture. Not sure of all the "many parts" you have replaced so far but am going to suggest just in case you haven\'t replaced and/or check or even know about the electronic distributerless ignition system module (EDIS module). It\'s kind of hidden and is a pain because if it is the original one it\'s rivited on. It has a 12 pin connector on it and if you are getting power when the key is on to the red wire, this could be your problem assuming you have checked all the fuses and wiring snd have a good ground there. There is a pink wire so don\'t get them mixed up due the the age of your vehicle and fading. It will be in the 8th pin location not the 3rd pin where the pink wire is. Above in the other pictures is the location of the EDIS module and a good picture of what it looks like. This goes out you don\'t have your power supply to the coil. It could be the EEC replay but just throwing this out to try and help. One last thing is I would really fully diagnose things before you lose any more money on parts that are not needed. I\'ll be happy to try and help you diagnose this. Hate to see people losing money trying to fix a problem replacing not needed parts. I hope this helped you out.

Hi and welcome to FixYa!
This will be caused by a faulty distributor coil. You may want to swap the coil and observe how it goes.
Hope this helps and thank you for using FixYa! Have a good one!

You are at thhe right trail what controls spark is coil pack crank sensor sparkplugs and plug wire but the most important is power . I mean 12 volt connections and ground This includes checking fuses you need a simple volt meter doesnt have to expensive or fancy just to pick up 12 volts let start with fuses in the engine juction box (there not mark to what it belongs to) make sure none are open. especially fuse 19 and 24 , next go to the crank sensor make sure the tabs are snuggly on now to the coil pack there is a red and light green wire this comes from ignition and feeds 12 volts at the coil pack measure that voltage is it 12 volts if not correct it this is from ignition switch ( you can make a tool that feed 12 volt with a wire and a fuse in series and attatch it to battery and the primary wire this is known as hot wire) next go to the ECM wiggle the wires see if that get a connection going if not go back to the ICM here are the wire you are to measure the tan light green, this is from ECM and it is pulsed it measure 5vlts to 0 volts switched then measure the tan orange the same thing 5 volts to zero,then tan white again 5vlts to zero. any one of these 5 to zero fails you fix is the ecm

Check to make sure the check engine light is coming on, on the dash, when you turn the ignition switch on. If it is not coming on, try leaving the ignition on for a few minutes to see if that light does come on and the jeep starts then. If so, then your ecu computer is in need of repair.
