if you look in the CE panel is there a relay that has a red and green LED on it??
Possibly and early 89 car?? Does the car have an electronic dash
You might have a bad relay

no,can't see any relay with a red and green light on..
My car does not have a electronic dash.
Changed idle stabillizer,vakkum elbows,hoses,floppy valve vaakum unit,knock sensors,injector seal's and gaskets,temp 2 sensor in 2007.
Changed spark plug wires,spark plugs, o2 sensor after it started running on 4 sylinders.
Could it be that bouth my ignition modules are the problem..?

Why don't you swtich the inboard and outboard injector leads and see if the inboard cylinders start to fire.

No this is a batch fire car, not sequential.

Nord, if you're not up on the terminology, batch fire means each injector fires with every pulse. The atomized fuel collects behind the intake valve until it opens.
If the inboard injectors don't fire but the outboards do after the swap then its time to replace the inboard injectors.
