C 2500 Truck 2WD V8-5.7L VIN R (1997)
14.
Install the J 44466-10 (5) to the J 41413 tank (3). The J 44466-10 regulator is preset to 150 psi.
15.
Connect the J 44466-10 hose (1) to the J 44466-12 (3).
16.
Install the J 39021 Injector/Coil Balance Tester, the J 39021-210 Injector Tester Adapter Box, and J 39021-301 V6 Fuel Injector Test Adapter (1)
or J 39021-302 V8 Fuel Injector Test Adapter to the metering body electrical connector.
17.
Adjust the amperage selector switch on J 39021 to 0.5 amps.
18.
Open the valve (2) on the tank (3).
19.
Open the valve (4) on the J 44466-10 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.
20.
Close the valve (4) on the J 44466-10.
21.
Energize one injector using the J 39021. Observe a pressure drop on the gauge (6) and verity the injector/poppet valve operation. An
injector/poppet that is "stuck" and not operational will have no pressure drop on the gauge. It an injector remains "stuck", repeat the procedure
multiple times (as required) until the injector is operational.
22.
Repeat Steps 19, 20 and 21 for each individual injector to verify that all injector/poppet valve assemblies are "unstuck" and functional.
23.
Shut off pressure valve (2) on the tank (3) of the J 41413.
24.
Bleed off the pressure at the J 44466-10.
