Gee oh Dee It shouldn't be too difficult to check for a fried computer. Does the CEL come on when you go to start the truck? Or pull it out, open it up and look at it. You'll see burnt components or leaking caps. Prolly smell a fishy smell, too.

Neil F. Did you replace the TPS? That's were I would start.

Jerry Bransford Remove it and return it for a refund. Even when they work, a Jet Chip does NOTHING until you're at near redline RPMs and at wide-open throttle, not exactly how many drive their Jeeps. By federal EPA law, such chips cannot do anything at all in any other condition other than WOT and at extremely high engine rpms.

I hope your ECM wasn't fried.

Mr. Sinister sorry bud, you probably fried the PCM. just another reason why these chips/tuners aren't worth it.

Installed Chip Now WON'T START! HELP!

The Story:
1.Plugged in jet module chip into the ECM followed all instructions to a T.

2.Jeep Started and Ran great, Then the check engine came on with a P0123 code which was throttle position sensor problem

3. Took it to autozone turned it off, checked and erased codes.

4. Tried to start up again (with chip in), and it just cranks and cranks.

5. Took out aftermarket module thing and set everything back to stock and still won't start.

7. Disconnected battery and ecm for an hour to reset (still wouldn't start)

6. Checked pins in ECM for bent or pushed but it was fine

8. Tried unplugging TPS and starting (no Luck)

(of course Jet costomer service says it's my fault somehow and sorry they can't help)
