Question about 1991 Volvo 740
Car wont start or shuts down while driving.fuel pump temporarily shuts down.
My 92 740 regina would crank sometimes and sometimes would not. I reached behind the engine and felt a cable (crankshaft sensor). It had exposed wire and cuts. This fixed the problem. I also have to clean the positive terminal connectors on the battery. One of them, if not clean, will cause it not to crank. I don't know about the pressure regulator. I have not messed with the pressure regulator. You can pull the fuel line going to the fuel rail off. It is a rubber fuel hose. Attach a clear tube and run it into a empty bottle. Attempt to crank. The bottle should get fuel in it. I can't remember how much it is suppose to get. It will tell you if you are getting fuel to the rail.
