Make sure the solenoid is plugged into the ECU correctly. It is very easy to miss the pins in the ECU when you insert the connector. The other thing you can do is just eliminate the fuel solenoid. I don't use them in my models. I prefer the simplicity and increased reliability of a manual fuel shut-off. You just have to make sure you turn it off at the end of a run and before you fill the tanks again.
