Ford ef not switching over to gas, use to hear it click over but not anymore? anyone had a similar problem or know how ti fix it?

Thanks

First thing is to check with a test lamp if there is power (electricity) to the lock off solenoid at the converter. If yes, then the lock off is faulty, if no, the black box that controls the gas is faulty. If the solenoid doesn't "click" I suspect the black box. You will only get power to the solenoid for about 2 seconds if you don't start the car.

yeah took in to mechanics said my lpg computers stuffed, need to find a one on here or a new one is $300, hopefully i can find a decent second hand one on here.

thanks
