Since you made no mention of running problems after it starts, I'm assuming it runs fine after it starts, so I would give the fuel pump & filter a free pass for now. (It's much easier to look at the injectors at this point than to get a FP tester & check the fuel pressure (although this may be in your future) If the injectors aren't spraying fuel when first cranking, then the ECU is not grounding the injectors for the start. This is usually due to the ecm in the dist. not sending a strong enough pulse during cranking (slow speed) While you have the hood up, look at the wires coming from the distributor. Do you have the 4 wire plug?
