injector cleaning

[WCKDGT]

is there anyway or is it possible to clean the injectors by taking them out 1 by 1. heres the story of why im doing it,http://www.stangbangerz.com/forums/showthread.php?t=32465

its got about 3 gallons of 4 yr old gas and now i cant keep it running. i did a fuel pressure test and its only reading 7 on he gauge, ive blew out the lines change the fuel filter, i know i should have dropped the tank but it started up so quick i thought it would be ok as soon as i dilluted the old gas w/ new gas, and i added seafoam to the tank but it cant work if its not running. any input or suggestions on what i should do wld be very appreciated

i work at a dodge dealership and we have a fuel injection cleaning service, its just this can that you attach to the fuel rail and the engine runs off this cleaning stuff while it cleans ur fuel rail and injectors, so id imagine they'd have something for ford to do this but im not really sure
