What causes the green light to flash without switching to gas in a gasoline-to-gas conversion?
2 Answers
If the green light flashes without switching to gas in a gasoline-to-gas conversion, it might be due to a stuck fuel pump or a malfunctioning fuel pump, which can cause sudden fuel supply interruption and engine stalling. Introduction to Gasoline-to-Gas Conversion: It involves installing a natural gas system in a conventional gasoline-powered vehicle, allowing it to switch between gasoline and natural gas, effectively making it a dual-fuel vehicle. When the coolant temperature exceeds 60 degrees Celsius, the system can switch between natural gas and gasoline. When the natural gas is nearly depleted, the system can also be forced to switch back to gasoline mode. Pros and Cons of Gasoline-to-Gas Conversion: The advantages include cleaner and more efficient combustion, reduced carbon buildup, superior anti-knock performance, and no dilution of engine oil, thereby extending the lifespan of internal engine components. The drawbacks include a potential power loss of 10% to 20% in some converted vehicles, increased vehicle weight, and slightly reduced performance compared to running on gasoline.
As an experienced taxi driver with eight years behind the wheel, I know this issue all too well! When the green light flashes but doesn't cycle, it's usually a problem with the gas system. First, check if the pressure reducer feels icy to the touch—it's common for that hunk of metal to freeze in sub-zero winter temperatures. Pouring hot water over the return pipe often does the trick. Just the other day, I encountered a stuck solenoid valve in the gas tank, and a couple of firm taps with a wrench actually fixed it. If none of these are the issue, there's a good chance the gas-powered ECU is acting up. Disconnect the battery cables and wait five minutes to let the computer reboot. Remember to check the gas tank pressure gauge before diagnosing any fault codes—if the needle doesn't reach 1.8 MPa, there won't be any gas supply. In that case, heading to the gas station for a refill is your best bet.
