I have a stock 96 Civic EX, 5 speed, 144,000 miles that decided to stop starting on me one day. Here's what I have checked

-Engine will not turn over
-I can pop start the car no problem
-No codes found
-Checked ignition fuses under the dash
-Battery is fully charged
-Battery terminals are clean
-Jump starts do not work
-Idiot lights stay on when trying to start the engine; HVAC and radio turn off
-Headlights stay fully bright when trying to crank
-Fuel pump primes
-Clutch safety switch is currently bypassed (using paperclip)
-Relays click under the hood when trying to crank
-Brand new starter (Purchased 9/10/11)
-Starter can be jumped
-No alarm system that I know of

As you can see above, I've tried almost everything I can think of, and what I could find on this site. Does anyone have an idea what to check next? I've had the car for over a year and it has never done this before.

 

I would check condition of large cable that connect A+ to starter motor or just replace it with new.
I would check incoming voltage to starter solenoid (small wire going in to the starter motor) with ignition key in start position. If you don't have multimeter, you may hot wire to supply battery voltage to solenoid on the starter motor.

It is possible that the starter motor relay in cabin is clicking but not letting voltage go through due to dirty/worn contacts.

And that is my best guess of the day.

 

Thanks for the suggestion. I just checked the clutch safety switch again, and I noticed one of the contacts was very loose. I pulled that pin, or whatever its called in the plug out, pulled up the back of it, and it snapped back into the plug. I put the paperclip back in, damn car started lol. I've been working on this thing for hours today in the heat and couldn't figure it out lol.

 

Good to hear that!!!
