Jeep wont start... dash doesnt even light up or beep, but have full power
It's been happening the last week or so and finally yesterday I had to get it towed home. I can't get it to start let alone even click. On top of that the dash doesn't light up or make the beeping sound. The radio doesn't work, but everything else has full power. Battery is a few months old, the negative terminal has been replaced (going to replace the positive terminal today as it's rusted and a little loose), and the starter relay has been swapped around with a non essential relay. Within the past week if it didn't start I'd pop the hood jiggle around the fuse box around, push the fuses in, and it would start. Ideas? Jeep is a 2005 Rubicon with a manual transmission.
I have a 04 X that was having the same problem. Couldn't figure it out. Replace ignition switch, cleaned terminals, replaced relay. Took the fuze out for the clutch safety switch. Finally had it towed to local Jeep repair shop. Turned out to be the ignition actuator and another part which I cannot remember now. Don't know which was which but the one piece was in the steering column behind the ignition, which ended up being broke. Cost me about 200$. Haven't had a starting problem since.
Pulled the entire ignition again. A buddy and I concluded it's coming somewhere from there and not from the fuse box. If we jiggled the key around, the dash would light up and it would start beeping. However, after the clutch is pushed in, the beeping and dash shut off again. Sooo... I suppose it's either the ignition or where it plugs into the main harness (black box looking thing)...
In the connector that plugs into the ignition switch. There are 3 red wires & all should have battery power to them. They all come from the PDC (fuse panel in front of the battery) & since you said you giggled the wires up there to get it to start, one could be bad. Also check all the terminals (10 of them) for any discoloration or signs of excessive heat & make sure none are pushed back & possibly not making full contact with the terminals in the switch when plugged in.
