Hey guys, i need a quick concensus before I go dismanteling and figuring out the problem, but there's an 89 SS im thinking about buying, and i was chargin the battery the other day, and when i put it back in the car would catch , turn over a few times, and die, (it was working fine a few days before), this kept happening repeatedly and even after feathering the gas and pumping it it wouldnt catch and keep idling. My only guess, since nothing else was touched, is that the little bit of gas that has been sitting in there for a while has gone bad and become contaminated from the other crap in the tank. so unless anyone else has any suggestions, i was going to flush the tank and fill it with new gas.

Specs are,
Big Block 396 V8 bored 30 over
11 to 1 T.R.W Pistons
Steel Crank
530 Lift Hydraulic Cam
Closed Chamber 219 Intake
