I have a 2005 tc40d that I thought I ran out of fuel. I spent days priming with no fuel going to injectors. I had fuel to injector pump but not past that. I cleaned the injector pump and boom fired up. Then it wouldn't shut off. I now believe it was the fuel solenoid malfunctioning. Problem is I can't find it. Can anyone tell me the location so I can troubleshoot it.
