So I have a 93 Camaro 3.4L that won't start.

Initially, the car would start, sputter, then I would give it some gas and it would be ok.

Then, it would start and then shut off immediately. With a couple of tries, I eventually could get it started. It turns out that my vacuum hose connection (the rubber 'T' in the middle) was old and cracked, so I bought a new assembly and installed it (the big hoses and little ones on the left), and even put in a new PCV valve. I checked and double checked the connections and the car just won't start at all now. I'll crank it and it just won't catch...every so often it will act like its going to (and it sounds strong) but it just won't start. My battery is still strong enough to turn the engine over (for now). I'm out of ideas, anyone else got any?
