I have a 1990 F-250 7.3, 5spd. Went to turn off the truck and it kept running, when the key was off all electrical turned off, so I stalled it in 5th to stop it. next I checked the power to the fuel shut off electrical Ok , I had and extra switch but where the problems began, while the engine was running I pinched the fuel return line to stall the engine. but it started missing and blowing white smoke up on restarted before changing the fss switch , I went head and change the FSS, now is shut off properly but still missing and smoking , then I replace the fuel return lines and bled the injector line the miss and smoke continued and cleaned all the injectors still no change , Where do I go from here?
