please help!!!!! jeep wont start now

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!

Try swapping the coils to find a faulty coil, try swapping the injectors to find a faulty injector, or start by doing a compression test to all 6 cylinders. Hope this helps

I always like to start at the beginning. Why was the car on ramps to begin with?

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

If it didnt do it before you pulled your exhaust down, then you may want to go back and look for anything you may have damaged when you pulled the exhaust.

Sounds like a strictly electrical problem. Tow it to someone with a code reader and see what codes are coming up.
