The only thing is it will run rich and foul the plugs and contaminate the 02 sensor and the enviroment.Some of the European cars don't even have a Lambda system and the mixture is adjusted by the screws. As far as the cold start valve. It's use as a primer for the gas system and to be used on start up only. During the summer, I most of the time keep my hot start relay plugged in to avoid any problems. 100 degree + weather outside. Yes: I have a new accumulator and my system starts up fine. As far as a fire hazzard, It's no more of a fire than gas in your tank or any thing else when gas is around. If you leave the cold start running all the time, then yes you have a gas feed problem but the cold start can wash the cylinders but most likley it will gas foul the plugs and won't start or quit running. The accumulator that holds the pressure on the gas lines could be the culprit at this point. John Hervey www.specialTauto.com
