E8C Fuel Shut-Off on Starting
E8C Fuel shut-off on startingWhen the starter motor is turning the engine over, the fuel supply will be shut off if the accelerator is floored (720 butterfly angle).
1 Lift up the dust excluder on one of the injectors and connect the test prods to the two injector pins.
Polarity: red test prod (+) to the blue/red (BL/RD) lead and black-test prod to the green/red (GR/RD) lead.
2 Engage the starter motor and check for voltage across the injector.
3 Press the accelerator to the floor.
4 The injectors should remain without current as long as the starter motor is engaged. If not, check the operation of the throttle position sensor, see E5. If the throttle position sensor is defective, fit a new one.
Check the green/red (GN/RD) lead between pin 3 of the throttle position sensor and pin 12 of the control module. Check the lead between pin 2 of the throttle position sensor and one of the engine grounding points.
