CRD Common rail diesel fuel rail pressure tester and signal simulator

This tool connects to the crd rail pressure sensor and harness via molded connector plugs, no fiddling with back probes. It automatically detects which system, Bosch, Delphi or Denso.
Once the engine is cranked over, the tool then directly displays the signal as Mpa, psi or bar.
This will immediately tell you whether the fuel system develops enough pressure to activate the injectors and start the engine. In the event that the engine fails to start, possibly due to a fault in the pressure sensor, it is then possible to substitute a pressure value to the PCM to help determine whether you have an actual pressure fault or a perceived fault due to a faulty pressure sensor.
All this data can be gathered in minutes by making two connections.
Use in conjunction with scan tool live data to verify that the pressure reported by the pcm is the same as reported by the DM7-508SCR

If you service CRD vehicles you need this tool.
