Starting problems... Injectors? Timing? PLEASE HELP!! :(

OK, I am having some trouble starting my car. I pulled the motor / tranny to rebuild the motor, cam it (T-Rex), and drop in a new clutch. So I put the motor back in the vehicle, and reinstall everything etc. etc., try to start the vehicle, and it will turn over, but not start. Checked all grounds, plugs, etc. and everything was fine, and still no start. I pulled one of the plugs to see if the motor was sparking, and it was. I can smell fuel when the motor tries to turn over, but the plugs are not wet at all and they doi not smell of fuel. I wonder if it could be the injectors? I also got a partial tune from G-Force to make sure I don't blow up the motor while I break it in.

Also, some info on my setup:
Rebuilt stock bottom end (New bearings, etc.)
T-Rex cam
Lucas 42 lbs/hr injectors (A bit overkill I know, but I have room to grow)
Full exhaust
TR55's
Stock plugs

Please help, I want to drive my car!

Did you boost up the fuel pressure to feed the injectors?

I would imagine that it would still try to start with a differance in pressure, but then again, maybe not.

Yup, I have good pressure in the lines, but I am wondering if I put one to few o-rings on the injectors, and they're leaking the fuel where the injector meets the rail. I put one where the injector plugs into the rail, and one where the injector plugs into the intake manifold. Like I said, the plugs are not wet at all, and they don't smell like fuel. But here's the trickey part, I smell fuel when the car is turning over. Gah, all these problems... it's been 8 months and I just want to drive! lol

Pull an injector and turn the car over and see if any fuel is being sprayed out of the injector.

Put the injector in a glass and disconnect the coil packs so you don't start a fire.

Usually takes two people.

OK, I'll try that in the morning tomorrow. I wonder if it could also be that I am missing the ground that goes from the driver's side frame rail to the alternator? The brownish copper mesh strap, with two bolt loop ends on it.

The injectors are not firing when the car is turning over. What could cause this?

Does a bad crank sensor cause injectors not to fire? The injectors are getting power.

Car has been sitting for 8 months and was in an accident before resting.
