Maybe???
If I had to guess I would say the pcm is not turning on the 3 sec prime to the fuel pump. This is controlled by the distributor. the pickup coil sends signal through the module to the to the pcm relay which in turn grounds the fuel relay for 3 sec prime until it sees rpms, I would say you are not getting this. Make sure the distributor is tight, otherwise it will not ground and turn on either relay. Meaning if it is loose in the block it may not ground. My suspect would be a bad pickup coil in the distributor, because this, not the E-coil is what usually kills the TFI module. First I would test the fuel pump relay for the prime signal, it is a green housed relay next to the brown pcm relay. These relays, are either next to the PCM or under the drivers seat I believe. I would check for a prime signal and power there and if present i would either replace the relay or take the cover off the relay and manually engage it. if the pump fires and the car starts, and If all the variables are there then I would say you have a bad realay. If there is no prime signal I would head to the distributor where you have already been. Like i said earlier make sure that the distributor is tight if it is not then the TFI and the pickup may not be getting the ground they need to make things happen. Otherwise i would bet on the pickup in the distributor. Let me know if I can help on anything.....
