I will mention ahead of time that all the fuses were fine and I was getting power to the fuse from the ignition.... thoughts, ideas, guesses?
But ,, were you getting power at the fuel pump ?? you have to chk that before you condemn the fuel pump ,, could be a bad fuel pump relay. and believe it or not i have seen ignitors on those early years cut the power to the pump ,,
if there was power at the pump , than i would had to guess a bad pump, clogged screen , or some inside the tank , clugged lines,

I bought the fuel pump because time was running out and the parts store was going to close, so If I needed it I had it if not then I could return it (as long as it wasn't installed), so I replaced the fuel filter (it needed it anyway), and tested for power, nope, zip, nada, so I removed the fuel pump relay and jumpered the ignition to the fuel pump and low and behold, I have power! but still no fuel... obviously since I had power to the pump at this point and no fuel (I had the line directly off the fuel pump disconnected) the pump was in fact bad, so I replace the pump and with my fuel relay jumper in place I've got power, replaced the fuel pump relay and no more power to the pump.... now what?

Sir_Nast:
How about the distributor rotor having a crack in it and also corroded tip..then check the resistance between the coil primary terminals, if the coil fails check it and replace with a new Part"(s)

I checked the resitance at the coil and it was fine, bought a new relay and put it in.... same problem... so I was beating my head against a wall at this point... removed the distributor cap and it looked a bit dirty so I cleaned the contacts a little bit, still wouldn't start (I had the fuel pump relay back in place at this point, so I'm still getting spark and fuel but not running) tired starting it a few more times and then all of the sudden it worked.... replaced the main relay (the origonal, put it back in) and car still started and ran fine, put in a new cap and rotor and haven't had a problem since, it starts and runs like a champ now.... I'm just dumb founded that a fricken distributor cap/rotor did this.... I had never seen that before... the rotor looked fine, the cap was a bit dirty but no signs of it arcing elsewhere, and I was getting consistent spark when I tested for it.... but now it's all good.... just about drove me nuts though since it was freezing outside and I was litteraly sliding under the car on a sheet of ice that had formed below it....

ok, now you got me confused,,,,,,,,you said that after you installed the new relay there was no power at the pump.........a distr rotor will not cut off power to get to fuel pump ,,

You can understand my confusion now as well.... with either relay in place the car failed to supply power to the pump, if jumpered it worked fine and after the troubleshooting it started to function normally with either relay in place.... I don't know if disconnecting the coil for testing rest something or what but all I know is that this problem was a major headache...
