donnaquiroz	1989 Nissan 240SX won't start. Battery weak. Finally got new one. Help! Ran strong, starts easy. Battery weak. Idle is a little rough sometimes when cold. Battery gets worse idle also. Sometimes have to compression start, starts easily runs fine. Put on diagnostic, battery bad, rest strong. No problems for 2 days driving only day time. Shut off, next day won't start or compression start. Got new battery, now turns over but no start. Does not flood. What is most likely problem?

Could be lots of things but most likely you have a parasitic drain on the battery that drains it overnight--as for no start, probably trying to start it has fouled the spark plugs.

You can buy a spark tester very cheaply to make sure you are getting spark and you could take the plugs out and dry them off or clean them.

Here's a test for PARASITIC DRAIN
