i have an 02 ap1 im dealing with that wont start, random day of time just decided to stop. ive tested the battery has 14v. ive swapped the starter, changed the start/stop button. ive changed the relays for stater cut relay, swapped clutch switch aswell, checked all fuses. not getting power to the 7.5 signal wire under the dash fuse box. vehicle starts if i bridge a wire in the under dash fuse box. i removed starter cut relay & bridged it with a paper clip. starts right up. any help?

 

Just buy this car? -- If so you know why it was sold. Seems the car starts fine but won't crank.

What were you doing or had you done when this started?

"Won't start" means what? Starter motor won't spin? Spins but won't fire? Can you push start the car? Appears it starts and runs from your work-around.

sorry for the lack of details. its my personal car. it was working fine until one day it just wouldnt start. i went inside for an hour or so, came back to turn on & no crank or start. no noise, only main relay & fuel pump kicking on. if i remove the starter main relay under the dash & grab a paper clip i can bridge the starter to turn, causing the vehicle to start. ive changed the starter main relay with a new one. still nothing. if i roll the car it will start aswell

 

Checked ignition switch function <Key switch>

 

need help please! (starting/signal wire issue) - S2KI Honda S2000 Forums
diagram here

 

According to that diagram,most likely culprit is the clutch interlock switch. If that switch isn't indicating clutch depressed, then cut relay won't close.

Most likely issue, the $1 white plastic stopper on clutch pedal. This is what presses against clutch interlock switch plunger.

Did you find a couple pieces of mystery white plastic on drivers floor? Plastic gets old and crumbles.

You can buy new plastic stopper, or tape a dime in its place, or use your paperclip skills and bypass the interlock.

Clutch pedal has 2 switches. Interlock is the top one. I'm tild replacing the plastic stopper (or the dime trick) requires removing clutch pedal from car. Not all that big a deal, but a pain nonetheless.

 

Clutch interlock switch.

 

Said he swapped switch,but yes follow link ^

 

New switch would still not fix if missing stopper.
