I found that I am not getting voltage to the WUR. I tested the fuel control pressure and had 33 psi when cold and rose to 45 psi in about 1 minute when I applied 12 volts (from a battery connected directly to the terminals) to the WUR. Does the control pressure sound correct?

From the electrical diagrams it seems that power to the WUR should be supplied from the same relay that operated the fuel pump. The fuel pump works fine, so I have a bad connection somewhere. Any ideas where I might look for such a problem?

Thanks again

if the car has a frequency valve/oxyen sensor system, the relay is probably bad. Attached by the ECU in right rear wheel well.

Saturday was supposed to be my first drive with others Ferraris here in Louisiana. I went out this afternoon to start it up and check the A/C charge. (I will mention now that I cleaned up on the engine since the last time I started the car, but it was mostly just the rear valve cover area)I immediately noticed it didn't fire right up like it always does. I let it turn over for a few seconds and finally it started. It was barely running and I could smell gas fumes. I pressed on the gas pedal and it only barely changed the idle because it was so flooded. I shut it off and waited awhile for the fumes to evaporate then started it again. I let it run long enough this time to burn the gas off the plugs and it began to idle a little more normally, but still flooding. It would also backfire if it got below 2K rpms. I had my wife keep the idle at 2K while I unplugged a spark plug wire from each bank. Both were firing. I removed the air filter and check the plate movement (per the Bosch book). It seemed smooth all the way down, but it took some effort to move it. The Bosch manual says it should move freely. How much force does it normally take to push the plate down? I then checked all the electrical connectors I could find and all were OK. I then disconnected the cold start solenoid and the throttle position switch, with no improvement.

I've given up on my drive tomorrow, but would like to fix the car. Where do I start troubleshooting a flooding problem?

Thanks for any help
