Is the distributor locked out?

What fuel are you running?

What plugs are you running?

How are you checking the fuel pressure?

Thats a good start.....

There's your problem. You flow an NOS cheater system thru the fuel jet BEFORE the solenoid, not thru the solenoid and the plate. You will need a flow tool to do this properly. Unscrew the fuel line from the solenoid. Make a flow tool that screws on the end of the fuel line with the fuel jet in the end. Then set your desired flowing pressure. Put it back together and go race.
