i have a 2000 civic si that would not start in the mornings only. i checked out the battery at autozone and it was ok. i even tried hooking up the booster cables with another car and it still wouldnt start. The only way i could start it is pushed and then it would run and start fine the rest of the day. I replaced the starter, did a tune up, everything seems to be connected properly. its a freak of japanese nature. ne ideas???

what it does when i try to start it is like an electric noise, it doesnt click or turn over.

BTW i have an alarm system but its connected properly so iono.

 

could the the ignition switch on your steering column. It could be working when it wants to, and maybe the cold is messing with it.

 

Check the fuses, relays and the clutch/starter interlock switch (if MT).

 

i never thought of the temperature messing with the starter switch, ill keep that in mind. also the clutch/starter switch ill have to look into that. i havent checked that.

 

dude apperantly its the flywheel that was messed up. according to my mechanic. i doubt it because if it was that shouldnt it mess up at all times im trying to start it, instead of just when its off for over 4 hours like overnight.? iono, im guessing he's the pro here but im doubtfull.

 

I'd be skeptical of the flywheel too unless it's warped or missing a lot of teeth. I'd be more wary of the input shaft on the starter being stripped or something. I dunno if there's an inspection cover on the trans that you can look in on the flywheel. How did he arrive at that diagnosis?

 

yeah he removed the cover and said that the flywheels bad, thats why it starts sometimes only.
