Thanks fasteddy. I'm finishing up my irrigation system this weekend, but will do these tests and report back. The wire is connected to the power steering pump, but I will check the wire for integrity.

One more thing I forgot to add. I pulled the cat off to see if it was plugged. I can still see light through the catalyst, and there was no change with the cat removed.

EDIT: Ok, here are my results:

Using the sensor in the middle of my face, there is a slight smell of fuel at idle. Not strong, but what I would consider normal.

Removed solenoid wire and separated fuel line at the main fuel line connector at the firewall. Pumped gas into a cup via a hose for a count of 10 seconds by stopwatch. Measured JUST slightly over 400ml.

Pinched the return line off with a towel and a set of needle nose vise grips. No change in engine power.

I noticed this time around the check engine light came on, which was not on before. Going to search how to check codes on this thing to see what it pulls up.
