Fuel pump sending unit resistance check test 

This time we have a Fuel pump module removed due to a fuel pump check valve failure. Module will be replace. As part of our training at LATTC in Los Angeles CA, I decided to shoot a video on how to do a fuel sending unit resistance check. This test can help a technician when facing erratic fuel gauge issues. Note that this is not the only test that can help when diagnosing fuel gauge problems. Enjoy and God bless.
