Finally this car (90 VDP) gave me a code, 22. I have done the suggestions as the hynes and the AJ6 system diagnostic guide have suggested. Still no sound of that fuel pump giving that initial burst. I even have another working ECU that I tried. Anyone else tackled this 22?

 

I am a little confused on how to count the pins on the blue ECM connector.I am not sure which way to start counting. I need 7, and the color code of the wire is KN, that also has me confused.
I am trying to diagnose as pic one describes with this circuit issue. Pic 2 and 3 is the connector, and the colored wires. Any help would be great.

 

I had a friend come over, because trying to work on that fuel pump issue by myself was difficult. He was able to get under there while I turned the key, the fule pump was seized. Car is running again. I did fix a few loose connections on that blue connector to the ECU, the 22 code is gone. Thank you gentlemen. I'm on the road again.

 

Thanks for the update , good to see it's fixed

 

Hey Mr T.....thanks for coming back and advising of the fix
