Well, it sounds like you're trying to throw parts at until the problem goes away. Very bad idea.
Fuel Air Spark Which of these is missing?
I realize you are wanting someone to give you the magic answer, but without some test results, they can do no better than to throw more parts at it as you have done so far. And, by the way...how is THAT method working out so far??
I suggest you get out your FSM and and a paper clip and start there. (You do have an FSM, yes?) Grab your VOM and fuel pressure gauge and go hunting. NOT MPS? You got me there. WTF is MPS?
It might be as simple as result of low voltage - which can cause a host of problems. OR, it could be some bad injectors. If you have alcohol blended fuel, have you measured the resistance across the injectors?
