Thread: car wont start after plug change,HELP

I will try and keep this short. The other day, me and my brother changed his plugs in hi 1990 240sx with a red top sr20. The car was running before. we changed the plugs and the motor would not turn over the first couple of times. then it started up. Drove it around and everything was fine. got back turned it off, then tried it again and started right up. then the next day would not turn over. tried several times and will not turn over. Any and all help will be GREATLY APPRECIATED.

sounds like the starter to me, when it does it again tap the starter and see if it winds over

Starter, or batt.

The battery is good i believe. This problem only happened after the plug change. Is there a ground in the plug harness that could have come loose that might cause this? I tapped the starter and nothing. Same deal. Thanks for the quick response.
