DESCRIPTION:
This procedure tests for fuel injectors ability to deliver a metered quantity of fuel.

NOTES ON FAULT TREE:

1. Fuel pressure is OK at this point. An injector flow test will be run next. Used with the power balance test (Chart A-4), this will determine if a weak cylinder that does not give an rpm drop in the power balance test is caused by fuel flow or spark. A remote start switch can be used to actuate the fuel pump through the fuel pump prime connector.
