I'm assuming in 2002 that this engine is 100% mechanical injection. I think this engine even has a mechanical camshaft driven lift/fuel pump similar to a fuel pump on a old small block Chevy. Anyway, I'm told that it starts right up and runs well but then randomly shuts down. So I guess there is two directions to look. The fuel shut-off solenoid/wiring/power or fuel delivery system. If it runs fine until it quits, I'm guessing the injection pump is not the problem unless there's a fuel strainer that is clogged at the inlet of the pump. Am i missing anything on a older 4-390 engine that would cause random shutdowns???
