2007 sedan fuel pump not running and check engine light - Toyota Yaris Forums

I know this is an old topic but my 2007 Yaris is doing the exact same thing. This is my first post and so far this forum has been the only source online that has been of any use in fixing my car myself.

I've gone through and tested as you described and I'm getting no voltage on pin 4a-8. I was hoping that, you could tell me if replacing the body ecu fixed your problem? If the body ecu is part of the fuse box under the drivers side dash? And finally at the fuel pump, which wire is the positive an negative so I can test the fuel pump to confirm operation.

Thanks in advance!
