Try Travis at first class towing 403-200-9199 or rent a uhaul trailer for 80 bucks. As far as the no start I don't know what it could be sorry.

Check the ASD(automatic shutdown relay) in the engine compartment fuse box. It controls all sorts of stuff including the fuel pump and is a well known culprit for no starts on ZJs.

IIRC an ASD relay throws a code to right Clay?
did you pull the codes using the 'three key turn' trick? start there! likely you'll get a code.
also, the ASD is easy to check on the spot, just swap in a different relay in the fusebox and see if it fires up.
if you have no spark and fuel its a good place to start.

I tried swapping the relays and no go it still didnt fire..i talked to my buddy who is a mechanic and he said they are well known for crank positioning sensor i guess it shuts off fuel and spark to try and save the motor because it thinks the motor is out of timing.

Is this a V8 or 4.0, what year? The 4.0 crank sensors go all the time and are easy to change. The V8s CPS is pretty reliable and are a bear to change.
I don't know if the ASD will throw a code or not but pulling codes is a good place to start. I keep forgetting that the newer ZJs have codes available.....
If you press the shrader valve on the fuel rail do you get a good spurt of fuel come out?

It's a 1998 with a 4.0 liter there is no fuel or spark I had the plugs out and you couldn't even smell fuel when it was turning over the downside is that I'm in Calgary and it's in red deer. I just got tow company to take it to chrysler in the deer I'll let you know what it was.
