Replying to: slg123 (Jan 29, 2006 12:18 pm) Since the Liberty is only a 2003, I can't imagine any switch inside the vehicle going bad. In the engine compartment, it could several components which might be suspect. The gripe is, too much "juice" at start-up, therefore burning up the starter and or switch. It is simple to conclude there is an electronic short somewhere in the system. All of the "trons" are finding a path of least resistance going directly to the starter. So, I have to question, have all the wires/harness been "ohm'd" out? Any smoke/sparks visible at start-up? Any fuses blown? Any place where the outer shielding of the wires show signs of "bubbling" or discoloration? If the starter is being fried, then the starter has been placed in a postion as a "fusable link". I venture to say that much of the Liberty's wiring has been put under tremendous strain from over-voltage, that even if its fixed, then unsafe situations in the wire's integrity are almost guaranteed. The first thing I would tell the maintenance shop is to change out the starter circuit wiring harness and completely rewire the entire vehicle associated with voltage control, alternator, etc. For all know, it could be a bulkhead connector passing through the firewall, a wire shorting to the firewall itself. Documentation is the key in this situation! John |

I have now gone through 2 starters, 2 neutral saftey switches, and 2 ignition switches. It now starts on a consistent basis but makes a grinding noise. It never made the noise prior to the first replacement and now the regional tech is trying to tell me that this noise is "normal" and due to holding the key too long. All of the tech's at this dealer have acknowledged that the noise is not normal and is caused when the starter is dis-engaging from the fly wheel. I love my jeep but this is ridiculous. Any ideas??????

I have a 02 Liberty 3.7L V6. about 85,000 miles on it. never had a problem till two weeks ago. driving down the road and the car just starts stalling with the RPM gauge going nutz, then the cabin fills up with gas fumes,blows black smoke only when it starts acting up, check engine lite stays on, but not blinking. Had it towed to my local garage that I usually go to. They said my fuel injectors were dirty, plugs needed changing and did a VPS Fuel and air 3 step revita (whatever that means). Got all the stuff done to it, took it out 4 miles into the trip it stalls, same symptoms, RPM gauge goes nutz and smells of gas, cant restart it unless you let it sit for a few hours. Anyway, got it towed to the garage again, this time they said it needed two what they called Transmission sensors. They replaced them free of charge. Took it out drove it around town for about 20 mins then it starts acting up again just driving down the road doing about 35 MPH. same symptoms. This time I had it towed to a jeep dealer, they had the car for two days, call me back and said it needed a new computer (or engine control as they called it) about 500 bucks for it. So I had that changed, car worked again for about 15 or 20 mins and it stalled when we pulled up to the ATM machine to take money out. Same symptoms again, gas fumes, rpm gauge goes nutz, and check engine lite stays on. Had it towed back to the jeep dealer where its sitting today. Can anyone shed any light on this for me. Thanks for the help guys!

Replying to: b2272b (Jul 20, 2006 4:15 am)  Well I just got my Liberty back on Wedsnday, and after all those changes and it still stalled 4 times they came to the conclusion it was what they described as BAD COILS. So they replaced them. Like I said I got the Liberty back on Wedsnday and been driving it since today (sunday july 22nd) no problems at all. So instead of ur garage going nutz and replacing everything first have them check out the COILS. Cause this seemed to solve my problem as I described above. My garage gave me credit for the main computer they replaced and charged me 500.00 for.

Sorry about the long first post, but I really need some help. Am trying to solve a problem my Dealer can't resolve after weeks of trying. After about three years of little problems with my 2002 Liberty, I now have a big one. At about 38,500 mile (out of warranty of course) the engine start dieing. I took it to my dealer and they replaced the Crank Sensor. The very next day the engine died while I was driving 70 mph on the freeway again. I noticed the Tach jumped from 2500 rpm to 4000 rpm, down to 1000 rpm back to 4000 rpm, then zero. I could feel the engine struggling to keep running during this event. On the way back to the dealer, it died two times again while I was stopped at traffic lights. Right before it died the Tach always preformed a little dance; up, down, up down, up, then zero. The dealer has been unable to tell me what's happening, according to them - no error codes, engine electrical diagnostic all good, etc..... Last Sunday, I had to call AAA because it keep dieing a few seconds after cranking. I couldn't keep it from dieing without my foot on the gas. The AAA guy said I had bad gas, so we filled it up with 91+ and it stopped dieing one second after cranking. I was so happy. Unfortunately, my happiness lasted only one day. Everyday after work this week the engine has died after about five to ten minutes after starting. The last two days I've ran the vehicle in the company parking lot for ten minutes so it won't die on the road. It starts ok, but runs a little rough. After about five minutes, the Tach goes from 600 rpm (Idle) to 5000 rpm (the engine does not rev up) then to zero. the engine dies. I hooked up a diagnostic computer and read a P0320 Ignition/Distributor Engine speed Input circuit malfunction. (Dealer – No error codes!?) Where should I start? Spark plugs, plug wires? Distributor wiring? Thanks - Matt
