GTC605
Fuel Injection Analyzer


Canadian flag with caption

  The GTC605 Fuel Injection Analyzer is a hand-held instrument designed and built for the diagnosis and performance measurement of all types of fuel injection systems, including almost all solenoid, piezoelectric, and mechanical injectors used on diesel, gasoline, and liquid natural gas engines. This tool is faster, easier to use, and more comprehensive than any fuel injector tester on the market, because of the unique (patent-pending) sensor system.

  Using the GTC605 is as simple as clipping the ground wire to a chassis ground, and pressing the sensor against a fuel injector; you don't have to disconnect or remove anything, and you can check all the fuel injectors without even turning off the engine. You can find out whether an injector is receiving ECM/ECU signals and moving in less than 10 seconds by going to the 'tachometer' mode in the 'digital' view, and looking at the three indicator circles (control, power, and motion).

  We recommend spending about 20 seconds per injector checking each 'open time' in the 'chart view', because most problems cause injectors to stay closed or stick open too long. If some inconsistency is observed, we usually take a look at the 'on time' in the 'chart view', then the 'waveform view', to make sure that the injector is receiving strong signals from the ECM/ECU. If the ECM/ECU signals are strong and clear, we usually look at the 'open time' 'waveform', as this shows the current to the injector, along with the injector's response. Finally, if none of those approaches works (which can happen on an occasional misfire), we look at the 'open response time' and 'close response time' in 'chart' and 'comparison' views.

Comparisons with Other Tools

GTC605 vs. Automotive Lab Scope

    The Fuel Injection Analyzer has five major advantages over a conventional automotive scope:
  1. The GTC605 does not require the fuel injector to be disconnected or back-probed, making the GTC605 faster and easier to use
  2. It analyzes the signal to get timing information, and can display it digitally or in chart form for the detection of occasional misfires
  3. It can detect and display pintle motion
  4. It can detect and display injector current (without having to purchase or connect a current clamp)
  5. It is more portable and durable than an oscilloscope

GTC605 vs. Fuel Injector Pulse Tester

    The Fuel Injection Analyzer has three major advantages over a fuel injector pulse tester (A.K.A. electronic fuel injector tester):
  1. The GTC605 does not require the fuel injector to be disconnected or removed, saving time and effort
  2. It tests the fuel injector under real operating conditions, which include the ECM/ECU and fuel pump
  3. It finds the injector response times, which can indicate mechanical problems in the fuel injector

GTC605 vs. Diesel Injector Tester

    The Fuel Injection Analyzer has three major advantages over a diesel injector tester (A.K.A. injector pop tester):
  1. The GTC605 does not require the fuel injector to be disconnected or removed, saving time and effort
  2. It tests the fuel injector under real operating conditions, which include the ECM/ECU and fuel pump
  3. It finds the injector response times, which can indicate mechanical problems in the fuel injector
