decided to upgrade the relay/fuse box for AUX stuff. Was going to order this guy
http://www.dirtboundoffroad.com/aux-relay-fuse-panel.html but it is backordered. so I pieced it together myself woohoo, let me tell you he saves a real headache when they are in stock...

Had anybody ever heard of a coolant temp sensor causing a vehicle to not start? Got told on Friday from repair shop that that is the problem with the car.

If any of the sensors go bad, it shuts the pcm down.

Ok. Guess I just couldn't wrap my head around a coolant sensor causing it to not start

Not quite fore, there are preset defaults in the pcm for it to still run
However if a sensor is reading incorrectly but still within range the pcm won't know it's bad. For instance a temp sensor reading that it's 95 degrees when it's only 35 degrees at start up would cause the injection. Pw to be too short and not give enough fuel to run.... kind of the same scenario as an inoperative choke on a carbed motor

Depends on how the sensor fails, for sure.
If a sensor fails and shorts the 5V/7V/8V (depends on year of jeep) sensor power bus to ground somehow, the ECU may shut down, I'm not sure, but it certainly won't be able to run the engine.
If it just fails and gives an obviously crap value, the ECU will usually detect it and the engine will probably run badly and get terrible fuel economy.
If it fails and gives a sane-seeming value like eflores said, you can have some real weird problems.
