electrical and check engine from tcs problem on 1996 Acura RL

my car is really great a solid running car, but when I don't drive it for a day or so it won't start, the cd player doesn't work and the engine light does not work. Could all of these problems be related? Has anyone else had this problem?

Fuel pump relay is for car will crank but not start or car stalls while driving.
Neutral safety switch is for car wont start in Park ... but in Neutral it will
Can you give some more details? Does the engine crank over?
