from your posts it sounds like there is a blown fuse in the vehicle. If the vehicle cranks and doesn't start and no power at diagnostic plug, then there is a power issue somewhere. A direct question for the dealer you should ask or maybe they told you, did the dealer scanner not power up at all or did it power up and the scanner couldn't establish communication with the computer. If the scanner didn't power up at all, the first thing the dealer should have done was check all the fuses. If there is no communication with the computer, then it could be a cut wire or a bad computer. I had a couple of chrysler cars blow the ignition fuse on a rainy day for whatever reason that didn't even have aftermarket equipment on them. Replaced fuse and was just fine. What area do you live in?

It would not power up their equipment and they blamed it all on the alarm - I tested and it did not have ground for whatever reason, I grounded that wire however I am still very curious as to why it didn't have ground.

They have since come back and say that they can power up their equipment but don't have communication with the engine and that the computer needs replaced, I happened to have the factory computer (i had a mopar performance replacement in there) and haven't heard back since then so hopefully this morning there will be good news, but the way this has gone so far I am not very opptomistic about it.

I am in Nashville, TN - I really wondered the same thing about the fuse....I checked the ones under the hood but didn't think there would be one inside that was going to be tied to the ignition system and all that, could be wrong though...

It sounds like the crank senor on the bell housing went bad. If it's cranking but not turning over.
