i have a 2000 civic manual with a b18. Driven everyday with no problems until this am. I try to start it this morning and it wont crank and when I try to it loses all electrical power for a few minutes then the power comes on and everything works until I try to start it again. it doesn't even try to turn over. The battery is good.
thanks

 

Are the battery connectors clean and tight? Are the G1 battery ground and the G3 transmission ground clean and tight. If those are fine, test the ignition switch.

 

The battery connections are good. My radio has 12 volts. Ill have to check the grounds. Would the ignition switch cause it to lose all power temporally?

 

When you lose power everywhere else?

Have you noticed that when you turn your key off, nothing has power? Does that answer your question?

 

radio has 12 volt until I try to start (old pioneer with gauge displays)
I lose absolutely all power when I turn the key to start, with the key on or off. until it come back a few minutes later.

 

I actually had this happen the other morning to me, I thought I was some type of electrical drain my car was having, after checking what would be obvious, I noticed something on my floor board and realized the neutral safety switch had lost the little rubber grommet that makes contact with the switch to engage it. This may be your problem, assuming your car is 5 speed, and isnt bypassed, if so a simple cheap fix is what your looking at. Hope this helps

 

Clutch switch is intact
Both grounds are good
It's that it loses all electrical power when i turn the key that really has me stumped. Would a bad starter do that? All fuses are good too.
Thanks

 

fyi I jumped the starter to check the starter and it started. And now it works with key. I guess ill drive it until it does it again so I can trouble shoot more.
thanks
