Dual gas tanks and why not remove one
I have a 1989 six cylinder with fuel injection and two tanks. Yesterday, the truck just died on the expressway like it lacked fuel. It sputtered and when I was pulling off the road it came back to life just enough that I felt is was a fluke until I passed the next exit and then it died for real.
I could crank the engine and it wanted to start but it just died when I released the starter switch.
First, I would like to pick up a simple wiring diagram of the fuel supply system so that I might understand how to diagnose the problem. Are there any on line?
It would probably be easier if I had only one tank. I don't need two tanks, so what is the downside to removing or disconnecting, say, the rear one? Is there anything that I should be concerned about?
I stuck a probe into the schraeder valve one the fuel line behind the engine and I got fuel to come out but I can't determine the pressure. I suppose the fuel pump only comes on for a few second is the engine does not start; is my assumption correct? Does that apply to all of the fuel pumps?
