After consulting the wiring diagram, I'm still pretty sure of where I'm headed. The valve gets power from the "main fuel relay" (also known as the lambda relay) which also powers the lambda module. Power runs to the valve on the red/purple wire. The ground is switched by the module at the red/brown wire. Red/purple has power. The lambda module has power. I pulled the plug off and checked the green/yellow wire which powers the ECU. The ground wire for the module is attached so the module should function because it has ground and power. It still appears as though the freq valve ground wire (red/brown) is broken or the module is not switching ground. Bill, if you're still in the area please call my cell. 202-359-8205. I'd like to borrow your module to test with. Thanks, Rich Yahoo!
