Tony's knows no starts. A failure to start, cranking, but the engine will not run. Check for good voltage, engine cranks strong, spark is good and the injectors click correctly. Now add some propane and the engine runs for a moment, so I know its missing fuel pressure. A fuel pump test shows the pump has a ground and power from the relay that the ECM turns on during engine cranking. The next thing is to look at is the fuel pump motor. Is it doing any work. An amp test while power is applied to the fuel pump will show if the pump windings are making a connection. The pump draws 6 amps, but does not pump. We have a connection, but the pump does not spin up and pump fluid. Time to replace the pump. Tony's installs many fuel pumps every year. We see all types of vehicles that need fuel pumps replaced. The average life span of a fuel pump is around 8 years. Your results may vary. Tony's Service Center Phoenix, Arizona 85016
