Unplug the connector to the fuel pump relay and look at the contacts. Mine were not making good connection and caused the same symptoms you are having. I found replacements at Pep Boys for 3.00.

Something about the relay connects, they are cursed ! I replaced modulator, cap, rotor coil, still wouldnt start! finally we cleaned the relay connects and that solved our problem.
