2008 Lincoln MKX currently will not start just constantly turns over and lights constanly flicker. Have tried chargign the batter and then it shows to be charged but does not start though.

Look for a body control module that s acting up.

I am having the same problem with my 2009 mkx. Were you able to pinpoint and fix this?

My 08 MKX needs a new computer - the # 2 cylinder coil is burnt up for the 3rd time and the computer is not communicating with that cylinder and my A/C compressor will not kick on. Every mechanic says they cannot be related, but the problems both started on the same day!!! I have had three different mechanic change the No. 2 cylinder and it's strange because it's melting, but it is still doing the same thing. They have concluded I need a new computer. Good news is they are not as expensive as I thought they would be. I also found a used one at a junk yard for less that $300 dollars, but I'm scared it may not work if we install it ourselves... any ideas??

So many parameters are monitored by the engine light and its system.
From O2 sensors to a misfire to even a gas cap not on correctly.

One cannot troubleshoot if the light if it comes on and back off intermittently.
Once it comes on and stays on can it be checked.

But, just a hunch...try putting in a tank of high test gasoline that has NO alcohol in it.

Check Engine lights are notorious for coming on due to alcohol being burned and that fuels ineffeciency.

Hope this helped...

The best solution I have for you is to try to buy the Chilton Manual for the 2008 Lincoln MKX.

I can't copy and paste wiring schematics off of my online resource to fixya.com for some reason.

Sorry, about that.
