^^ x2, check the small 20A fuses in the fuse box under the hood, I'd bet the one for the ASD relay is blown

That, or crank sensor is bad and the lights are just a coincidence.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

Crank sensor and cam shaft sensor are the two that will cause it not to start right?

Two of the ones that can. The crank sensor and o2 sensors can short out causing the ecu to not boot. giving no gauges while cranking, no cel either.

my cousin had the same problem with his '96 GC, it was the body control module (BCM) that was bad. we put in a new one, and it started right up!

I hate when old people poke me at weddings, point and whisper, "You're next." So I've started doing the same thing to them at funerals

i think you need to get a multimeter out and track down the draw.

Gauge cluster, wiring, ecu, bcm, could be a lot of things

Recently replaced my evaporator so naturally I had every harness disconnected. Once I put it all back and started it up I had no cluster whatsoever and it only idled for about 3 seconds and died each time.

OBD wasn't giving me any clues so under the dash I went and disconnected and inspected/cleaned every quick disconnect on every harness. I even pulled the cluster out and checked the connection there.

Magically after 45 min of that nonsense it started up and everything worked. Its the long way but who knows.

It sounds like you have a short but you may get lucky and find a corroded/shorted terminal somewhere.

Good luck

I got it fixed... I learned my lesson i bought this jeep about 4months an never thought it would been a bad ground... Thier two braided metal grounds that attach to the back side of the motor by the driver side val cover to the firewall them a ground goes from the motor to.the frame... Jeep to not like sh*t for grounds make sure u always have a back up ground on the battery if you plan on puttin some mud on them tires...... An i fixed the mph gauge the wires holding the speed sensor were not holding in the plug... Nothing but a Lil tape can't fix...
