    Cant start car on lpg all of a sudden!!!

    I've parked the car up as I replaced the suspension and now it won't start on gas (petrol pump not working) all of a sudden can someone help me with this please? I have a 1993 discovery with the 3.5 if that helps.

    Cant start car on lpg all of a sudden!!!

    Lars04 ....do you have the switch that has the four (green) lights with the button that you can swap over between LPG and petrol?

    If you turn on the ignition on there's one single light (on the LPG switch) that is flashing amber above the lights (in green) indicating the level of LPG in the tank?

    If you press and hold down the button that normally switches between LPG and petrol until the amber light stops blinking the engine should start on LPG only.

    When its blinking it will start only on pertrol and then switch over to LPG after a few sconds.

    My (electric fuel pump) is working intermittantly and Im running her on LPG only.

    Hope that assists,

    Cheers

    Gday mate, Yea I've got that switch , and yes I do hold the button down my fuel pump isn't working either well the whole take is out of the car now I've been running only gas since I got it. I took the tank out then moved it (gas running fine) parked it to change the springs now nothing! I'm going to install an aftermarket external fuel pump and ditch this gas system one I'm not a fan of gas and also it takes up to much boot space.
    Thanks for your help.
    Cheers
    Lars

    Hi Lars

    Bugger ......Hoping that bee utey picks up your thread.

    He's a full bottle on all things LPG .....I believe that's his trade and if he doesn't maybe send him a private message.

    He's one of the most helpful members and his advice has been invaluable to many on this site.

    Hope you get it sorted shortly .....

    Cheers

    Diagnosis thrives on details. "Gas don't go, haaalp!!!" is summarily lacking in detail, makes it hard to be useful. Pictures, closeups of switches, valves, fuses etc may help. Have you looked at the back of the switch yet? Probed the terminals with a test light and see what comes on when?

    And today I got one just the same, "Gas don't go, haaalp!!!" on an old Hilux, fortunately his petrol system was still working just well enough to get to me. Turned out that the line fuse for the LPG was somewhere under the bonnet, and the holder's lid had fallen off. The fuse had got wet and corroded slightly and there was a tiny bulge in the plastic body of the fuse. So although the fuse was visually intact it wasn't conducting. A new fuse and a bit of pliers love on the holder and the gas sprang back to life. All it took was a methodical approach to the system checking one item at a time.

    So have taken a few pictures, I've got power at everything but the picture you see with my finger pointing to the red wire there is no power which leads to the tank which I don't understand as I have power at the start of that wire in the engine bay?. I ran a wire straight from the battery to that wire and I get a click on the solenoid in the engine bay but not at the tank.
