starter issues on my 91 vert
 

new deep cycle high amp battery, new alternator putting out 13.25 volts and my car still wont start if i let it sit for more than a couple of days.
i put the new battery in drove it for 3 days let it sit for 3 more then wha wha wha wha... nothing! took the battery in to be tested and they said it was at full strenght so i popped the clutch drove for 20 min. started it again then went home, next morning same thing.
so i have 4 theories, tell me what you think.
1) the starter motor is weak or failing or the solenoid is pooping out.
2)i have a battery drain that i dont know about and it is sapping my battery (but that doesnt make sense because it does this with a full charged battery too).
3)vapor locked?
4)bad connection between battery and starter?

also i got under my car today and found a big round hole (size of a quarter) on the bottom of the bell housing of the tranny and i could see right up to the fly wheel or whatever it is called that the starter shoots out and grips on to.
it didnt have threads like a bolt was missing so i am wondering if this is supposed to be open like that or should it be plugged and could this have anything to do with my starter issues?
thanx
corey:wallbash:

oh yeah! one more thing.
i get popping and slight back fires when i decellerate or shift gears at high rpm (above 7k) and my gas mileage is terrible, like 15 mpg!
so si this a sensor issue or vacuum doohickey or maybe i just drive too hard?

yeah!

any body there?
 

buuuump

the hole in the bell housing is supposed to be there. sounds like leaky injectors to me....

o and the popping and backfires could be due to your tps.
