Oil Injection Pump Circuit
Resistance Test
The oil injection pump circuit includes the engine
wire harness, the injection pump winding and con-
nector, and the oil injection control circuit of the
EMM.
Disconnect the battery cables at the battery.
Use Electrical Test Probe Kit, P/N 342677, to
make a connection to pin 23 of the EMM J1-B
connector.
Calibrate ohmmeter to the LOW OHMS scale and
measure the resistance between pin 23 of the
EMM J1-B connector and pin 1 of oil injection
pump connector.

An infinite reading ( ) indicates an open circuit.
•
Isolate the faulty wiring, connection, or injection
pump winding. Repair faulty wiring or replace
faulty component and retest.
For a higher than expected reading, test resis-
•
tance of the injection pump. If injection pump
resistance reading is approximately 2-3 Ω,
injection pump winding is good. Isolate faulty
component. Repair faulty wiring or replace
faulty component and retest.
