car wont start, electrical problem?
im trying to help my buddy start his car... its a boosted 8 with the whole 9 yards.
at its current state its flooded but thats not the issue, ive deflooded 7s and 8s multiple times... we hooked up his microtech to the laptop and it reads 11.2-11.8 volts WHILE the battery is on jumper cables.. when we try to crank it the volts drop down to high 9.x and loww 10.x volts.. everything seems and sounds spot on except it doesnt feel like its getting enough juice to fire up.. i deff think its electrical but idk what it could be.. these trials we tried with an optima yellow top (the one he has been using) and a brand new red top he just bought.. both yielded the same results so i wanna say we ruled the battery out? the car also has a hks grounding kit so it doesnt seem like its that either....
however he did say he heard a spark in the engine bay after he changes his coils... the bhr ones i believe.... tried those and the stock ones and no luck... any suggestions what to trouble shoot?

Steve you use to have the mazsport ignition it required different dwell settings did you change it to the BHR specs for dwell? Im not sure i matters but just a thought. Oh and my ground was loose a couple times where the mazsport kit use to ground an extra fuse block on the right hand side fuse box do you know what i mean if not ill take a picture for you just trying to think of every possibility.
