What happened when EFI motorcycle started without oil pressure?

When EFI motorcycle starts, there is no oil pressure, which may involve many parts such as gasoline pump, fuel tank, gasoline filter, EFI, oil pipe, etc., and the wiring of these parts. It may also involve some sensors related to ignition system and their wiring, which affects the oil supply and leads to the inability to start without oil pressure.

When EFI motorcycle starts, there is no oil pressure. First, check whether there is no gasoline in the fuel tank, or whether there is too little gasoline, whether the gasoline filter is blocked, or whether the fuel tank cover is not ventilated, which affects the oil output of the fuel tank. Check whether the gasoline pump is damaged, whether the wiring of the gasoline pump is open or whether the wiring plug is loose and inserted. Check whether the tubing is discounted due to other circumstances. Cleaning the throttle nozzle and nozzle blockage is one of the common faults that lead to fuel injection failure.

Check whether there are any problems with various sensors related to the ignition system, such as crankshaft position sensor, throttle position sensor, intake pressure sensor, air temperature sensor, oxygen sensor, inclination sensor, etc. , and whether their wiring is open or poor contact and virtual connection, etc. These sensors sometimes affect the oil supply and oil pressure.
