92 2.3 190 Fuel Pressure/Delivery Issue

[kregghill]

I have a 92 190 2.3.....
This is what I know about this issue. Car was running fine, I go in the store...come back out and try to start, car starts for 1 second and I hear what sounds like a vacuum hose pop off?!?! I go to start the car and it will not start. Car turns over fine. I took it to a friend of mines shop and he checks the fuel pump/fuel pressure. The car is producing 85 psi up to the injection unit however the fuel pressure is not popping off the injectors?!?! Has spark, and car starts when you spray carb cleaner into the throttle body?!? My friend's repair manuals do not go into detail about the 92 2.3 because from what I hear... that engine was very limited production in US that year. Could someone please provide some feed back as this is my daily driver and I need her back!
PS...If you could please provide a picture diagram of the injection system and possible fixes I'd appreciate it!!!!
