  post locked   2008 Honda Civic LX 1.8L 8th Gen Fail Start / Slow Crank  

this happens once or twice a week (inconsistent) only after the car has been sitting overnight. once it's started it never has this problem again for the rest of the day. it always eventually starts if i keep trying (the most fails i've had in a row was like 4 or 5). i replaced the battery twice already so it's not that. any ideas on what it might be?

We don't care what generation it is.
We need year, make, model and engine size.

You are losing all voltage. You have a connection problem somewhere in the power supplies.

All the power connections starting at the battery and including the fuse box.

If I had to guess (and I do).....It almost sounds like you have an intermittent draw on the system draining the battery overnight.....Like may be a light getting left on?....trunk? glove box?

Cranked up normally after several tries. Smacks of bad OE u-bolts at battery get warm and finally make enough contact connection to deliver the amps t o starter. They can be tight and even look OK and not be as they are just cheap zinc coated steel I think.


Can be the other ends at starter or ground wire at engine block or anywhere battery cables travel - feel them for a weak spot in wire.


You can test this stuff for just voltage drop while trying to start it not just toss in new batteries on a guess,
