jeep to shop and the alarm is the cause?

I've had a Python 881xp on my Jeep for atleaset 3 years now if not more. I was pulling out of my garage yesterday and the jeep just cut off - when I went to start it back it turned over but wouldn't crank. I had it towed to the jeep dealer and after spending an hour they called to tell me my Jeep had all kinds of electrical problems and wanted to know about the alarm. I went down there to have a look and he claims that the diagnostic plug won't power up their equipment and immidiately assumed it was the alarms fault. There is a purple and white wire that do t-tap into the same color wires at the diag. plug. I looked up the 455t manual and it seems that those would be correct location for the wires.

He was quick to admit they have no troublshooting ability for stuff that isn't theirs, and because he can't get his diagnostic equipment to power up on my jeep and he sees wires he doesn't know what they are they are blaming it all on the alarm at this point. Does anyone have any ideas? Like I said it has been installed and working for years now - is it possible that the alarm is the reason that the jeep won't start? I can't tow the thing all over the place trying to get it fixed and at this point they said they can spend 3 hours just trying to figure out what is wrong with it.

Any help would be much appreciated!

a few thing that i have in question whatis the model and year of the jeep

but you can check some things no mater what the vehicle

depnding on where they tapped into the wires it is possible that some of the wires broke over time heat and cold can make wires brittle. I would go to each point that the alarm is tapped into the car and chech the connections. hopefully whoever did the install soldered and taped all the connections if they used t-taps that is your likely problem as t-taps tend to break a few of the strands of the wire and they will break the wire later on but if it is taped pull off the tape and check the connection give it a light pull not to hard if is broken it will come apart fairly easily and tada your problem is found

Thanks for all the help guys - a lot of it was done with t-taps...so I will go and check all of that.

If the ignition kill is activated will it even turn over, because my jeep will turn and turn all day, just isn't getting spark...

So if I unhook all of the alarm wires from the brain and where they tap in if they aren't soldered wires then effectively the alarm isn't installed - meaning there is no way the alarm is causing an issue?

Great info! I'll go check it sunday when I get back in town and post back if that fixed the problem

Make sure none of the connections were the t-tpas were used is broken ie not letting current through. If you lost an ignition wire I beleive your fuel system would not operate, but it would allow it to turn over. Make sure to unlug the 455t and double check those connections to the twisted pair wires @ the diagnostic plug.

Ok - lots to check but I should be able to accomplish all of that! Sure would be great if the jeep cranked right up, it was just so random how it happened - literally no stall, sputter, or anything - just cut off and wouldn't come back.

So does the starter kill allow the car to turn over or does it literally kill the starter motor meaning there would be no turning over or anything?
