starting/idle problem by runforrest

Hi all, have a 2000 Grand Cherokee 4.7 V8. had no real problems until today, pulled over for five minutes, engine off, head lamps on. would not turn over when I went to start it. ( battery recently flat due to wife! ) Got it started with jump leads and sounded awful, not firing on all cylinders and would not idle AT ALL. Whiring/slight screeching somewhere also.Had to be towed home!
Car has had recent LPG conversion. Switch to petrol, same problem. Any ideas????

Hello to all. I have a 2001 Sport and it's in great shape. No issues and no engine lights going on. This morning she just wouldn't start. Sounds strong when I hit the ignition, but just won't turn. I didn't see a code show up, but "no bus" did show. How seriuos is this, and what do I need to do to get her fixed. THANKS

I have a 1999 Jeep Grand Cherokee with 55,000 on it and it was running fine until my wife tried to start it after running some errands and all she got was a clicking noise and then nothing. I cleaned up the battery cable connections and made sure everything was tight. I then tried to start it but to no avail. I then tried jumping it but all that helped was that it would just crank. When I do try to turn it on the lights on the gauges come on and the gauges will go back and forth then stop but it will not crank? Is it something with the security system?...Thanks

how old is the batt?
these jeeps have to have a good batt or you have all kinds of prob
if batt is 2 or 3 years old get a new one try it you might just solve your prob

I replaced the battery and had a new key made..no luck. Mechanic from the dealership stopped by to program the key and stated that it is more than a key problem. Had it towed back to the shop. Also noticing a loud buzzing sound from engine fuse box which he had never heard before. He stated it was from the transmission control fuse? But it least it has power and will crank but not fire off...need some positive thinking..hope it is just a control module....

I have a 2001 Cherokee Sport and was having the "no bus" message show on the display while driving. It would be accompanied by an airbag and check-engine light, along with the speedometer and tachometer dropping to 0. I was able to either hold down the trip meter and "reset" it or wait 60 seconds or so for it to clear on its own. Took it to the dealership and they said it was caused by a faulty guage cluster connector. I never had issues with it not starting as a result, but thought it might help to know that "no bus" means there is a probably a break somewhere in the electrical system.

My 01 Cherokee Sport inline V6 just started doing the same thing, but with a #1 cylinder misfire code. I have changed my plugs (used OEM Champion plugs), cleaned the fuel injection system, and have a fuel filter on order at the dealership... no dice so far. I read something about carbon deposits on another forum and will try the distilled water flush next weekend before switching out the filter. My issue is also accompanied by a solid when resting and flashing when going above 30mph check-engine light. Please let me know if you found the fix. In retrospect, I think this issue crept up over the span of 1 month. Started with the occassional warm start chugging to now happening under any type of heat stress (stop and go/slow and go traffic).
