So I park my 93 hb for about a week and drive my other car around and when I try to start it up, nothing. Ok no problem I'll just jump it cause the battery is dead. Well nothing, so I go get a new battery and try it again. This time the car will crank but wont turn over. I was thinking fule pump but i can smell gas. I was going to check for codes but it isnt throwing any. I'm thinking it wont throw any if the car doesnt start, but im not sure.
Can I still plug it up to a diagnostics tester to see if something is wrong.

HELP
