batterie

CHECK THE PIPES FROM THE COOLANT RESERVOIR TO THE RADIATOR AND BACK TO THE RESERVOIR, COULD, CHECK FOR LEAKS.

check the 100amp main fuse located in the engine compartment fuse box the list of fuses will be on the cover but is easy to spot as is a large size fuse , there are sometimes another fuse directly attached to the positive battery terminal , if these are ok i'd have the battery condition checked as may be so low it will need replaceing , if you do have to replace the battery it is good practice to have the alternator charge rate checked at the same time as could be the reason for the faulty battery good luck

Why do you think it's the PCM?

you should never jerk the key out when it gets stuck put the shifter in park sometimes the shifter is not all the way in park you may have to keep moving it in and out of gear until it is all the way in park and you are not applying the brakes and wait for a few seconds and the key should come out sometimes you need to do this again

Probably Caused by old engine and burnt deposits on the valves and spark plugs. Change the plugs, add cleaner to the gas (get it from Pep Boys)
