I blocked the airflow meter vane flap open and nothing changed. Car still cranks but no fuel.
Looked at efi circuit. Discovered that efi relay (pin 1)was not getting voltage to energize. Used multimeter to test continuity from pin 3 to ground and ground side checks out 0 ohms.
Manualy energized efi relay (jumped pins 2 to 4)and fuel starts flowing out of filter. Remember the chk eng light did not illuminate with key turned but it did light up after I jumped the relay.
Also swapped out circuit open relay and ecu from junk yard - no change in symptoms.
Is there something elase to check that is common with chk eng light and power to efi relay? Could air flow meter be bad?
Thanks for your help.
Joe
