This week at BCIT students have checked static and dynamic fuel pump pressure testing. Followed by fuel pump volume and voltage drop tests. Tomorrow we will be onto current ramping with a lab scope and looking to calculate the RPM of the fuel pump! Exciting stuff in this fuel delivery course.
Looking for interesting feedback on the testing procedures and interpretation of the results for the fuel delivery system.
Picture to the right was taken by me from inside the fuel tank of very rare 1988 Mazda 323 GTX (all wheel drive turbo) that had quit running. There is an inch of rust on the bottom of tank. My class diagnosed a faulty fuel pump and this was the result of pump failure! Good chance this would not happen with a plastic fuel tank.
Keeping the injectors clean with Terra-clean! Edwin demonstrates the JB injector flush machine in fuel delivery class!
