Went to move our 2004 Wrangler(4.0 with 21,000+miles) yesterday. Turned the key, nothing.
Turned on headlights, nice and bright. Turned off headlights, turned on wipers, worked good. Ok. Son stopped by, so I had him tap starter with hammer while I turned key. Viola!! Jeep started. Ok, turned off engine and tried to re-start, nope. Tapped starter with hammer again while turning key, Jeep started. So, my question, is this a Starter Solenoid problem, or Starter. I had Jeep out mudding and in water about a month and a half back. Could I be having a problem from this now showing up? I'll probably replace the Solenoid first and see if problem clears up. Just thought I'd ask and see if anyone ever had this problem after getting in water and mud. (I'm keeping the Hammer in the Jeep for now) Ha... Thanks for any replies. Oh, before we tapped the starter, I had raised the hood and had son listen for starter relay clicking when I turned the key. It clicked. I couldn't hear it, but hey, at 57 I don't hear a lot of things anymore. Wife calls it selective hearing. Might be, but it works, sometimes!!
