Trying to solve my smokey start up problems, i changed my fuel filter last weekend, bled the air in the system and checked the health of my diaphragm by sucking on the hose. Went to start the truck up and it stammered a little and smoked some,then it wouldnt shut off when the key was turned in the off position. The only way i could shut it off was to pull on the heater or headlight knob. The FD knob wont light up either. I checked the fuses and all is ok. I pulled the FD knob and hear a click, so i assume thats ok as well. Any help would be appreciated. Thanks to everyone on this forum for everything!!!! If it werent for all you guys i would be lost.
