Will low oil pressure stop a 2004 Cummins diesel from starting?

Yes, low oil pressure can stop a 2004 Cummins diesel from starting. The oil pressure sensor sends a signal to the engine control module (ECM), which then controls the fuel injection. If the oil pressure is too low, the ECM will not allow the engine to start in order to prevent damage to the engine.
