I rent fuel pressure test kit - with engine off and running was 65psi. I don't now if fuel pressure regulator is good - no change when I disconnect vacuume hose. When pressure was on I check each injector for (spray) by two wires + & -.They was working (no leaking).

Are the injectors being pulsed when you try and start the engine? Will it start if yo spray carb cleaner in the intake?

Disconnect the fuel injector harness and measure the resistance of #s 4 and 6. See attached for specification.

I would also check compression and make sure the injectors are being pulsed.

Can you move the individual injectors around? Like put #3 into #4, and #5 into #6, and vice versa. See if the problem follows the injectors. What about plug wire impedance?

If I recall this has a distributor. What does it look like? What about the cap?
