Crummy situation ... the car cranks over like it's trying to start, but never actually fires up.
There's gas in the tank. I did recently put in a new fuel filter, and I know the first start-up usually takes a little patience because the filter has to fill with fuel--but this has literally been 15 start-up attempts with no success.
There was previously a very small fuel leak where the fuel exits the filter and heads toward the engine--the hose at that connection was brittle and coming apart. It would leak a little from there, but NOW when I've tried starting up the car, that area is bone dry.
