Question trouble shooting 91 190E

this is a continuation of a no start situation, I felt like I needed to put both situations together(as they popped up at the same time).
First we lost fuel and spark to the plugs. I began looking at fuel after hooking up my fuel gauges I found fuel pressure far to low, so i began testing fuel pumps after finding one very week I ordered two new pumps, that cured the low fuel pressure. I also replaced the fuel filter, We now have 5.4 and 5.0, so the EHA is set correctly now we have a situation with fuel to the injectors deflecting the plate you must go half way down before i get a spray from the nozzle.
Next is the loos of spark we only get one flash from the plugs when turning the engine over, I replaced the disy cap with one I had and the coil too, I found a small amount of corrosion on the coil wire, after that the spark got much brighter but still only one flash. ANY SUGGESTIONS?

yes I did and got no change at idle or start up level not until the flapper gets well down the chamber, as I said in my post.

As I just posted in one of your other threads... a 5mm deflection of your 'flapper' should take you from 0 to 60 quickly.

Something is amiss right there.

Yes sir, I thank you for your input. I am at the point of taking the entire unit off so I can inspect the arm and see if the through is off its privet.
