My 2000 Jeep Grand Cherokee 4.0 would randomly shut off after 2 seconds at start up. I would have to take the key out of the ignition , unplug the SKIM module
Under the steering column, disconnect the battery, wait 10 minutes and pray 🙏 that my Jeep would start and KEEP RUNNING AND NOT SHUT OFF AFTER 2 seconds.

A company in Florida came to the rescue. For $100, they will reprogram your existing Jeep ECM engine computer to “delete” or “bypass” the KEY AND SKIM MODULE which is the main cause for the jeep shutting down after start up. The security feature is good when it works. But Chrysler didn’t do a good job ensuring the SKIM didn’t go bad. So your key-skim-ecm begin to not behave. Like I said, my Jeep is a 2000 so I suppose the module just went bad.

Anyway, here is how you fix this issue:
Call All Computer Resources 1.866.699.5230 and tell them you want the SKIM module deleted from your ECM
Disconnect your ECM - passenger side firewall
Ship your computer to ACR
They do the work the same day they get it AND SHIP IT BACK TO YOU THE SAME DAY
**COMPLETELY REMOVE SKIM MODULE FROM STEERING COLUMN AND TOSS IN THE TRASH** if you don’t, the SKIM will be reactivated.. back to where U started.
Plug in the 3 plugs to your ECM. Then reconnect your battery terminals. Start up your Jeep and smile😎
