Default Fueling question
After the fuel pump has ran for the 2-3 seconds to prime the system for start what controls the fuel pump to run while the engine is running? I'm guessing it's the crank position sensor that controls fueling but not sure and thought I'd ask.

Thanks, I was hoping that was the case and it wasn't dependent on the ecm seeing oil pressure since I'm switching over to mechanical gauges for oil, fuel and temperature.
