Guys: Frankly, I just want to
Guys: Frankly, I just want to keep this simple, if I can.......I am not an engineer......nor, do I want to become one.
My plan is simple: The problem is in either the current flow to one, or both, the fuel pumps (elecrical), or the fuel output circuit, from the fuel pump (mechanical).......this would include the pump, FDs, warm-up regulator, etc.
My thought process needs to know WHAT exacly the problem is, before I understand how to solve it.
So, the first course of action would be getting the voltage readings at various stages, from the battery, to the fuel pump. I plan on using the wiring diagram to find the source of power to the fuel pump. I will then check the voltage (comparing to the battery voltage), to each connector, as it goes to the fuel pump..........the fuel pump being disconnected, at first. If any terminals are corroded, etc., then the voltage should change........am I correct, in this assumption? This will rule out power source problems to the relay, and fuse, and to the fuel pump.
If the above are OK, then I can assume good power to the fuel pumps. Then I will have to check the mechanical side.........that being the pressures of the fuel pump, etc.
