I would recomend checking your compression in each cylinder with a screw in type tester. Just to make sure the engine checks out mechanically. It seems odd that 4 injectors would fail to the point of not running all at the same time. Good luck with the car

Well, now I've checked the injectors and each is pulsing. also checked compression and is good. Also replaced spark plugs.

Ihave replaced the dist cap and rotor.

It sounds like you have all of the ingredients - fuel, spark, and compression. I notice that you said you replaced the cap and rotor. Hopefully you didn't use the diagrams in the Haynes manual for your plug wires - It is flat out wrong.

Here is a link to the correct plug wire locations on the distributor.
