i have a 2002 jeep liberty. it was sitting on car ramps for a week then when i went to drive it it was running on 5 cylinders .i thought was coil so i change that and still nothing . i changed all the spark plugs and it started to run on 4 cylinders. then it started working on 2 now it wont even start ! also did a compression test on one of the cylinders not working and showed fine.
the plug was wet so its getting fuel. any ideas what it is ? this been driving me nuts for a few days and i need it running asap!
i swapped the coils and it wasnt that. i didnt check the injectors but the plugs were wet so must be getting gas?.ill do a compression test on the rest of the cylinders. it was on the ramps cause i had the exhaust off to get welded
Check and see if you have power to the coils. With the key on, you should have 12v to one wire on each coil connector. The PCM controls the grounding of the coils to fire them. Now when you say it was running on 5 cylinders, then 4, then 2, then none at all, how did you arrive to that conclusion?
couldnt get any power even on the ones that run .maybe i did not do it correct.
first when it was on 5 cylinders i pulled the coil plugs one at a time till i found the missing cylinder. after i changed that one with a new one it didnt work still so i swapped it with one that did and then 2 were missing. im not really sure :S
Sounds like a strictly electrical problem. Tow it to someone with a code reader and see what codes are coming up.
