hi everyone, i was just driving my civic dx ls swap and it was driving fine when i got home i shut it off and decided to change my blinker bulb after i changed the blinker i went to turn it back on and it wouldn't start doesn't even turn over no click noise nothing the radio and lights work and i know its not the battery cause i tried jump starting it and got nothing.

 

Hard to say without testing...

Had similar problem with grandson's 93 Civic. Changed main relay switch for him and problem solved.

 

The PGM-FI Main Relay has nothing to do with engine cranking. 94

 

recent update....got a new battery and it started and ran fine. checked the alternator at local autozone and its fine. i drove it for about a week with no problems then again today it wouldnt start or crank.

 

Did you check the starter circuit, right above the link is posted by fcm. Its a very simple thing to check and will isolate the problem to either the starter, or the portion of the circuit that includes the ign switch and clutch switch.
