Let me understand you correctly, the engine will no crank/spin over, right? Do all the lights and horn work?
Ah ha! Check that security system closely, it may not be allowing power from the ignition switch to the starter/solenoid. If power is there when cranking, you may want to replace the battery cables completely instead of the ends that you already did.
if i pulled the fuse for the security system would that work at all or is that needed for the engine to run?
It's integrated with the computer system, so that won't work. You may be able to start the Jeep by shorting across the starter solenoid with the key on and in neutral. If it cranks that way and starts, the security system is at fault. That would mean that the computer system is interrupting power to the solenoid through the switch. I'll bet that's what's wrong!
Not if it's the security system, a shop will have to reset it first and see if that fixes it. If not, then repairs will need to be made after the proper diagnosis is performed.
Thanks again in advance for your ACCEPT,
No problem, it won't be that expensive though, maybe 150.
