Hey everyone, I bought a '91 CRX Si today, and the one problem I have is it only starts when jump started. I'm guessing theres a wire not getting enough juice or the batter, but does anyone have any other ideas what it may be?

 

need more info

 

once it's running check and see what voltage you're getting. if it's below 13.5 then your alternator is not charging the battery. if the voltage is above that however then it may be that the battery is toast. also check your grounds. chassis to front of engine, chassis to tranny, and main engine harness to thermostat. then check the power feed wire coming right off the alternator. make sure it's not loose or broken.

 

Bad alternator, Needs water in the battery, charge leak?

Some ideas.

EDIT: D16 is on the money.

 

bad battery? theres a few simple tests that obviously havent been tried yet

 

Could you tell me the tests, this is my first car and I'm working on getting it better. And yes it's a d16z6.

Thanks for the suggestions everyone, will check everything tomorrow

 

do you know how to work a multimeter?

 

Its probably your battery isnt putting out enough voltage but just try tapping on your starter and see if its starts without poping it

 

There are only three things that could be the cause:
1. Dead battery.
2. Bad contacts (corrosion) between the battery and the wiring.
3. The alternator is bad and doesn't charge up the battery.
