Ok. Tried to boost a dead battery when you know the engine will crank over.
you're kinda clueless about cars and how they work?
Does your engine crank over slowly? normal? fast?
Slowly could mean a low battery, bad ground from the battery.
Normal could mean something that doesn't require a boost.
Fast = bad. Ie No compression
You said that you smelled fuel. OK that means your not getting spark.
A few reasons, broken timing belt (ouch), bad plugs and wires(maybe), Cap and rotor cracked/worn out, ign coil under the dizzy toast.
