just bought an 83 2.3l with a 5 speed. it's been sitting for over a year but ran fine when parked. when i turn it over it just clicks once. put in a new battery and tried tapping on the starter, same thing. also tried jumping the solenoid. motor turns over by hand. tried push starting it and got nothing. it has a half tank of gas, do i need to drain what's in there or can i add new to the existing fuel? also, is there any way to check for spark seeing that it won't turn over? i'm lost on where to go next. any help would be greatly appreciated.
