Open the valve (2) on the tank (3) (see figure 7).
19.
Open the valve (4) on the J44466-10 to pressurize the fuel system. The minimum pressure required on the gauge (6) is 150 psi. If 150 psi. is not
obtained, the tank (3) must be refilled prior to performing this procedure (see figure 7).
20.
Close the valve (4) on the J44466-10 (see figure 7).
21.
Energize one injector using the J39021. Observe a pressure drop on the gauge (6) and verify the injector/poppet valve operation. An
injector/poppet that is "stuck" and not operational will have no pressure drop on the gauge. If an injector remains "stuck", repeat the procedure
multiple times (as required) until the injector is operational (see figure 7).
22.
Repeat steps 19, 20 and 21 for each individual injector to verify that all injector/poppet valve assemblies are "unstuck" and functional.
