I know it is frustrating, but dont let it get u donw to bad. Your truck has a problem, and you WILL fix it.
Have you tested the fuel pressure? It should run between 55-61 psi. I have heard of some return lines getting clogged and causing the pressure to back up and dump the excess fuel thru the injectors. It looks like there is a fuel pressure connection on the fuel inlet feed line. The test gauge can be connceted there, and when bled should give you real time pressure while the engine is running.
That CMFI (Central Manifold Fuel Injector) houses the pressure regulator, and also diverts all fuel to the poppet nozzles. It is located on the lower manifold and may be part, if not all of the problem. When you were able to get the codes for the service engine soon light, what were they?
