All things being equal: Are you getting any codes from the CEL?? That would be a good place to start. I assume all timing is good. You said that you adjusted the distributor- these distributors are not adjustable, the PCM adjusts the ground for timing +/- . I hope you did not use a CH07 RPT distributor from Oriley's, it will not work. At your fuel rail, is the pressure around 30# and when the vac line of the regulator is pulled does it jump to over 40#?? To me it seems more fuel related than timing. Check all grounds to body and engine. Check ground at e-brake for the fuel pump. Check fuel filter and pressure for pump or regulator. Think back to what was done if it ran fine before, something was not adjusted, not connected or broken when some of the other work was done.
