The invention contemplates fuel flow monitoring apparatus used in conjunction with an electronic fuel injection circuit for an internal-combustion engine. Electronic fuel injection circuits have vastly improved engine performance and efficiency, but their effectiveness has been hampered by the fact that fuel flow has in the past been monitored by mechanical fuel flow sending units. The instant invention eliminates the need for a mechanical fuel flow sending unit and replaces it with electronic circuitry which provides both an indication of fuel flow rate and total fuel consumption. The system also provides the diagnostic capability of monitoring fuel flow rate while the engine is not running.
