sr20det starting issues

[raptor727]

havent had any issues till lately. this is over a weeks time. had the battery checked and the alternator checked. both suppositely checked out ok. sometimes it starts fine. but when i need a jump it wont jump from another good battery nor jumper box, only a running car. starts right up when jumping from another car. when i turn the key it clicks which from my understanding would signify a bad battery or a bad alternator not charging. any ideas?

Is your battery draining too?

[raptor727]

doesnt seem to be, when i went to autozone they checked the drain on the battery and it was i think .5 volts it passed the drain test.

i agree with rb240mike its possibly your grounds cause mine has been doin the same thing for awhile now so so im thinking of hooking up another battery in parallel for better voltage capacity it this help me you should try it to just an idea
