I swapped a b16 into a 91 crx dx back in October. I haven't really had any problems with the thing until now. It's my dd and was running fine. I drove it Friday morning to and from school which is a 30 mile round trip. Parked it at home for a couple hours before I had to go to work. When I went to drive to work, it wouldn't start.

When I turn the key to the acc. or on position all the dash lights which normally come on and turn off all do what they normally do. In the on position, the fuel pump primes like it's supposed to do. When I turn the key to start, nothing happens. All the lights and stereo turn off (like normal) and it won't crank.

New parts include: alternator (installed in December) and main relay (installed in October).

All the engine grounds look good along with the battery connections. The battery is also fully charged.

I'm looking for ideas as to why it won't crank. I wasn't able to look at it today and won't be able to work on it until Sunday. Would it possibly be the ignition switch, starter, a relay, fuse, or something that I haven't heard of before?

 

Bump

 

Pulled starter had it bench tested, starter and solenoid both passed.

 

have you tried wiring the starter to the battery? also check your clutch switch.

 

I haven't tried wiring the battery to the starter yet, but I'm going to double check all under hood fuses tomorrow. The 50amp ignition fuse looked kind of crispy yet still intact.

I tried to find the clutch switch couldn't really see it. I'll find it tomorrow.

 

I got it figured out. Everything I checked electrically was fine.

Turns out, the plastic plug which pushes against the clutch switch when the pedal is depressed was destroyed.

I put an M8-1.0 bolt through the hole with a 1.0 nut on the back.

Thanks for the help.

 

Might wanna check the brake pedal bushing as well, after I replaced my clutch pedal bushing, not too long after that my brake lights stayed on. Had to replace that one too

 

I don't know why my first thoughts weren't that bushing. I had to replace the one for the brake pedal last month.

Thank you for the advice.

 

yeah...clutch switches and the blue crayon.... both are now super old and really should be stickied somewhere.

 

It totally should be. Maybe in the FAQ section or if there is an "old *** plastic breaks" section... Lol
