Won't start - 72 FI, used to start before engine drop Options

Interesting deal here:

Car ran a couple of years back but would die after driving it for about 2 miles. It idled fine for upwards of 20 minutes. I dropped the motor to clean everything off thinking maybe it was getting hot under load.

Now - engine is back in the car and it won't start. I got it to fire a bit by spraying gas into the intake but it dies pretty quickly.

checked for spark and have it at the end of all 4 plug wires (haven't pulled plugs)
I have fuel at all points i checked - injector banks, return line, etc. haven't checked actual fuel pressure - going to look at procuring a pressure tester - but the 1 and 2 injectors do spray ... and this is the part that confuses me - the 1 injector spurts when the key first goes to 'on' and the 2 injector spurts once while trying to crank, but then nothing. They don't spit out any more fuel while I'm trying to start the car.

I've been reading around here a bit and online and at pbanders site and I have a couple things I plan to check:

- double check the ground area under the intake manifold and clean all that up
- cold start injector - see if it's throwing fuel - it should be getting power while the starter is going, right?

I was also suspecting the trigger points - or maybe the connections between the points and wherever their signals go. Since the car ran before I don't think that they'd be 'bad', but I had a lot of stuff disconnected for a while during the cleaning of the engine and something may not be 'seated' properly.

So - I was hoping for some guidance on what to check while I'm in there.

Thanks!
