Default Leaky antifreeze and NO START

well the jeeps sitting in the school parking lot because it wont start or even turn over, the gauges dont turn on either, which i thought it was the battery but the interior lights come on and the door dinger goes off. so i dont understand whats going on there! the antifreeze is dripping off my crossmemember, my tranny oil pan, oil pan, and various spots under the engine bay.

no overheating at all ran just like normal, i got it home thanks to my wreakers insurance and we tested the starter (jumped it), the starters fuse, the battery and everything seems to be fine. the antifreeze stoped leaking, probly because its not running. im gonna try to get my uncle to come over with his car diagnostic computer thing, we'll see how that goes

The no start sounds like batt, or batt terminals, coolant sounds like a seprate issue.

I'd get a cooling system pressure tester to find out where it's leaking from without starting it. Sounds like it may be a freeze plug. JMO

well we figured out it has do do with the key switch not communicating with "the computer", where almost certain its a PCM fuse, so the next step is finding that, if anyone knows where the PCM and or ECM fuse is located that would help tremendously

as for the coolant, i noticed the foam in/under the hood is all stained in the shape of my radiator so im going to pressure test is once i can fix the starting issue

The fuses for the PCM are in the Power Distribution Center next to the battery under the hood. There's a diagram of it in here if you scroll down a few pages. > Jeep ZJ Wiring diagrams

if your talking about the one with all the relays for the fuel pump, starter, and horn, we already checked there and its not there, there has to be one that goes from the key switch to the computer... my uncle says it could be an "inline fuse"

That relay center is behind the glove box insert. Open the glove box, remove the tray/inside thing, and the relay center is right there. So I'm told...

ok so we figured out why it wouldnt start, the feed wire that goes to the ingnition was not working, so we hotwired it with another wire and it runs, but there has to be a relay that goes from the power to the ignition, if anyone knows where THAT is il have this all wraped up

i tried to look for the relay center behind the glove box and i couldnt get it off
