On my 1227747, I get power to the fuel pump relay and the pump runs for 2 seconds during ignition on. However when I go to crank the engine, the relay is no longer energized. Looks like pin A1 is no longer sending power to the relay when I try to crank.
Can anyone tell me what the ECU is checking if anything before energizing the relay coil on A1 during cranking?
I likely have something else wire wrong, but not sure where to start looking. For example is it checking the CRANK input C9 or some signal from the distributor perhaps, before firing the fuel?? I am seeing about 10 volts on C9 during cranking. Is that enough or does it even matter to my problem?
Thanks
