(e) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (FUEL INJECTOR ASSEMBLY - ECM)
OK -- Continue to next step.
12. INSPECT ECM TERMINAL OF MISFIRING CYLINDER (#10, #20, #30, #40, #50 AND/OR #60 VOLTAGE)
(a) Disconnect the ECM connector.
(b) Turn the engine switch on (IG).
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Text in Illustration
(d) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - BODY GROUND)
OK -- Continue to next step.
13. CHECK FUEL INJECTOR ASSEMBLY OF MISFIRING CYLINDER
(a) Check the fuel injector assembly injection (whether fuel volume is high or low, and whether injection pattern is poor) See:
Powertrain Management/Fuel Delivery and Air Induction/Fuel Injector/Testing and Inspection.
NG -- REPLACE FUEL INJECTOR ASSEMBLY See: Powertrain Management/Fuel Delivery and Air Induction/Fuel
Injector/Service and Repair/Removal
OK -- Continue to next step.
14. INSPECT INTAKE SYSTEM
(a) Check the intake system for vacuum leaks See: Engine, Cooling and Exhaust/Engine/Intake Manifold/Testing and Inspection.
OK:
No leaks in intake system.
NG -- REPAIR OR REPLACE INTAKE SYSTEM
OK -- Continue to next step.
15. CHECK FUEL PRESSURE
(a) Check the fuel pressure See: Powertrain Management/Fuel Delivery and Air Induction/Testing and Inspection.
