This just saved me from going through my hole start system to find my issue. It helped eliminate several possibilities of the culprit. I tried the needle nose trick, and what do you know? It turned over instantly. I noticed now that the ignition has a lot of play in it. I can wiggle it with the key, and it moves around more than I think it should. I seem to remember the ignition being very stiff when we first bought it. We had to push the key in quite hard to turn it back to the off position. So maybe that is my culprit.
Travis Halverson glad to hear you found information helpful. I have found that the problem is not the ignition switch,but more likely bad wire connectors that the start relay plugs into. I wired a push button switch across the two connectors you shorted with the long nose pliers. I found I would still experience failed to start times. I have found you can push the wires under the start relay location can produce better start conditions . I strongly feel this is the problem area. People have replaced the ignition switch and still have the problem. I have moved my wires around and have had good starting for a number of weeks. Good luck on trying this before changing ignition switch.
@@samowens44 , I found it interesting because I had just told my buddy that I was going to try rigging up a jumper wire and push button , and it was the next day when I came across your helpful hint. I was working under the hood and dash this morning pulling every electrical connector that I could, and cleaned them up and finished with dielectric grease. When I was in the relays, I found that the ASD relay was warm, and I hadn't ran the Jeep for hours. So I swapped out the ASD with the HVAC relay, since it was same part #. When I started it up, which was a surprise that it turned over. The cooling fan was roaring. I tested the relay with a battery and jumper wires, and it was clicking, but when I put the ohm meter on it, it was not good. So I googled ASD relay, and to my surprise, one of the things a bad ASD relay can cause is a no start issue. It cleared up other issues also. Such as my flooding issue. After driving the jeep and shutting it off for a few minutes, and try to restart it, I had to hold it to the floor because of flooding., I thought I had bad injector o-ring . Also some of my electrical ididn't work as they should, and that is now working right also. I thought maybe I had a bad ground somewhere. I did a 40 mile test drive, and got 5 or 6 mpg better than ever before. It is a 2005 grand cherokee limited 5.7 hemi, which I got last September and only got 2000 miles out of it. Then had to sit all winter because of not starting, So today was a nice surprise to finally get it to turn over. I will however be installing pushbutton jumper wire just in case. I hope all my rambling can help someone else fight the good fight.
@@travishalverson9186 I did find that a doorbell switch has a light inside and will cause a small current drain, so get a standard push button start switch to use. I am convince now that the problem is the connections at the Start Relay and moving the wires will correct the problem for long periods of time.
I'm wondering about the relay center wiring. I found it odd that it had a few relays that were pretty warm when I grabbed them. The Jeep hadn't been running. I hadn't even had a key in the ignition before that. The ASD and the EATX were the two that were warm, and they can both be causes of starting issues. I will be going to look at it today and see if the relays are warm. I replaced them yesterday, I was able to use a push button start mechanism off a snowblower. It was all I had around the shop at the moment.
@@travishalverson9186 if you are not getting the engine to turn over, the wiring diagram shows that there is no other wiring circuits the starter solenoid goes through. The ASD relay can stop the Fuel Injectors from working, stopping it from starting while cranking. Your problem will be in the Start Relay section most likely from what I have found. I think we can rule out the ignition switch and the Starter Solenoid and starter as the problem. The same relay can be removed and replaced and rocked around and correct the problem. It will come back in time. Just do the same thing, push on wires below the relay may help prolong the connection point for good results. It works for me. I started in 2012 and will go for a year or two without problems then come back. It has been working great for a month or so now.
