Re: 2001 silverado

Could be a wiring or a transducer issue, does the service light on the FMS panel stay lit or does it blink? If the light stays lit, then it may have had a repeat problem and may have locked you out of the ability to get any response from pushing the fuel select button "green", however if you do not have and fuel level showing on the panel, you will have to look at the wiring, fuel pressure or the pressure transducer. If you look at the transducer plug, it should have 3 wires on it, a green, a black and an orange. Verify that the ground is good "black wire" check resistance to ground. The green should be a 5 volts and the orange would be 0- up to 5 volts, depending on the pressure in the system, verify that the shutoff valves are open and that there is pressure showing the gauge, located by the brake master cylinder and let me know, Kevin

Re: 2001 silverado

Kevin the the tech and I am not but I have the same Eco kits on all three of my vehicles. The transducer failure is quite common but would not stop you from running on CNG. More than like it will be your servo or regulator that has also failed. If your local Kevin can take care of all of that for you.

Kevin, Glad to have you here...

Re: 2001 silverado

Sounds like the pressure transducer went bad on you. Try this first before replacing. Make sure you have enough pressure in the system, over 500 psi, unplug the pressure transducer and wait for the green lights to turn on, when they turn on, try switching over. The vehicle will probably need to be running when the lights are green, press the fuel select button and let me know what happens!! Kevin

Re: 2001 silverado

I have the pressure transducer's in stock, I had tried to call, but couldn't leave a message. Give me a call if you need this sensor, Kevin
