Thank you for your question, my name is ***** ***** I will be glad to assist you with your concern today.

Injector pulse come from the computer/mpem, this means if you use a noide light and have no injector pulse than you need to use a voltmeter and see which side you have lost be it power or ground (at the injector) next trace your wiring harness back to the ecm and check wires and connections including the ecm/mpem connector which can get corrosion and cause this problem, when everything external is eliminated the only thing left is the ecm. However in most cases you will find the problem with the other portion I explained regarding wiring/connections and connectors.

Thank you!
