[QUOTE="thetool, post: 17416, member: 1534"] Okay you might have a couple of different problems. The first thing you need to get squared away is the fule shutoff problem. Like Tazza said, it sounds like it may be out of adjustment. Disconnect the linkage at the arm on the pump, so that the solenoid plunger moves freely. check that the arm on the pump moves freely, and likes to rest on the stop position. If not, you have a problem inside the pump. When the arm is against the shutoff postion stop, see where your linkage lines up with it when the key is off. Adjust the length of the linkage to meet the hole in the arm, but don't bolt it up yet. Then turn the key on, and the solenoid should pull. Swing the arm on the pump to the run position, then check your linkage alignment again. It should be close. If so, bolt it up and it should work as designed. What you're describing sounds like the linkage arm attached to the solenoid is too short. When you turn the key on, the solenoid pulls and the arm goes against the stop, and the solenoid wants to keep pulling because it hasn't reached the end of its stroke, generates heat and melts. When you key off, it lets go but because the linkage is too short, the arm dosen't travel all the way to the stop postition, the engine dosen't shut off smoothly. Get that fixed first then go on to the Boss panel. If everything starts and runs, you may just have a burned bulb in the display, and it's so dim you can't see the bars. [/QUOTE]
