Oh ya, and the best part.....

Took the JK out to Calico this weekend tackled some new trails. Bismarcks hairpiece, Sushi burrito, Vodkaberry, Bismarcks backdoor and Doran. Strangely empty. We ran across one group of ATVs and a 2dr JK running together on fire roads. Beautiful day.

Update. I have the booster, MC and "seal" (o-ring really) in hand. I just sprung for the very $$ 68048758AA reservoir from mopar parts giant. I confirmed it is in stock,so I should have it soon. Then, onto the install. Hopefully have it done before the coilover kit arrives.

2007 TIPM's had issues. Pull your TPIM and look at date code, if it is 2006 or 2007, then it is original and a possible suspect. Here is my original TIPM details. Mine failed. The new one (or rebuilt actually) works great.

Run these tests on relay K3 to narrow it down: Check for 12V at Pin 86 Have someone turn the key to "START" You should get 12V at Pin 86 if the ignition switch is working properly. Check for Ground or PCM Control on Pin 85 The PCM grounds this pin when it's ready to allow starting (e.g...

Some of my j-scan modified data is gone after replacing TIPM, is this normal? My speedo is off, 50mph on gauge is actually 60. RPM's are off, more like a percentage. for instance, 2000rpm on dash is 1850 actual, 3000rpm on dash is 2500, etc.. Small stuff but annoying.

Praying for puppers!

Crazy question but do you have spacers on the hubs?

Not sure how this works but, maybe power is needed to operate or actuate the auto shut down. There should be 12v at some point during the cycle. Any 12v at any position of the key? Is it possible that ASD could mean “don’t let it start” if no signal is present, meaning when power is applied...

I think that points away from the ecm hopefully. M19 and M21 are ASD or auto shut down.

This is the type of live data it can provide. For your needs, it will confirm commands such as shut off… or run, etc. I am sure someone here has some ideas on what commands and sections to look at. J scan is vast.

This is the reader I use, it links to j scan app on your phone. You will have to buy a license that is tied to your jeep’s vin within the app. https://www.amazon.com/dp/B0D2W1SNJH?tag=wranglerorg-20

We need to find out what is supposed to turn off when the key is turned off. Do you have or have access to a j-scan reader? It will tell you what is happening real time as you shut off the key. It takes a little research to figure out but it is a powerful tool. Hang on I’ll post some links.

Good point.

To check if ECM power is actually being delivered (or stuck on), use a multimeter or test light on: Fuse M6 — Powertrain Control Module (ECM) Fuse M7 — Auto Shutdown circuit (also feeds ECM indirectly) Fuse M37 — Ignition Run/Accessory circuits These are typically 15A or 20A fuses in the TIPM...

Jumping the relay does not send the "turn stuff on" signal, starting fluid will ignite from compression on diesels. That may account for your sputter. Again, I feel his pain.

Can you pressurize the line by hand and see if it will run? A sputter is a good sign, some progress.

when you do the battery disconnect, make sure the system drains, like holding the brake pedal down to suck any residual power out of the system, I usually disconnect both pos and neg cables and touch them together for a few seconds to pull every last bit out. Be careful how you do it, both...

I know that disconnecting my battery reset my ecm. All the codes were gone, but a few did come back, so I t seems as though the disconnect worked. I would be concerned about the ecm as well, not trying to scare him, but it is a possible.
