purge solenoid question
i went to test the purge solenoid. hooked a vacuum gauge up to it. turned the engine on (cold engine)....there was no vacuum like there should be. then i let the engine warm up, and it's supposed to have vacuum on it once engine is warmed up. but there was still no vacuum. i took the solenoid off and hooked 12vdc to it and it would open no problem. i tested the connection under the hood and it's got 13.9 volts coming off it so the solenoid should be opening, but it's not. any help or info would be greatly appreciated.

check and make sure you have ground on the other wire in the connector, continuity or resistance check to ground

The ECU supplies ground when it wants to purge the gas fumes from the canister. Usually at part throtle/cruise conditions. What year and model is it?
