Fuel Injector Pressure Test

This test requires Injector Test Fitting kit,
P/N 5005844.
Disconnect the battery cables at the battery.
Relieve fuel system pressure. Refer to Relieving
Fuel System Pressure on p. 183.
WARNING
Protect against hazardous fuel spray.
Before starting any fuel system service,
carefully relieve fuel system pressure.
Perform
IMPORTANT:
mounted to cylinder head and fittings installed
with manifold retainer.
Use cap and tie strap to seal off outlet fitting. Con-
nect a 0 to 30 psi (0 to 207 kPa) pressure tester to
the inlet fitting. Pressurize the injector to 30 psi
(207 kPa). Pressure must hold for at least five
minutes.

Fuel Injector Resistance Test

Disconnect the battery cables at the battery.
Use a digital multimeter to measure the injector
coil resistance.
Fuel Injector Coil Resistance
2 to 3 Ω @ 72°F (22°C)
Use a digital multimeter with appropriate adapter
leads to measure the injector circuit resistance.
Measure resistance between pin 2 of injector con-
nector and the appropriate pin location of EMM
J1-B connector. Refer to engine wiring diagram
for specific EMM J1-B connector pin location for
the injector circuit being tested.
