Fuel Pump ? (1 Viewer)

Hey Folks, i just replaced my petrol pump, been running on LPG for a while, when i used the fuel pump yesterday the car ran a bit rough but i expected that ,
but on the highway could hear the engine spluttering slightly, and when i went to turn the engine off, it repeatedly starts dying and starting up again even though technically it was off (keys were in my hands not in ignition)

now i have no idea whats causing this, any suggestions ?

Cheers

I havent but mabie another owner did, i have noticed the same thing happening on LPG mabie twice but only for a second or less, revved a little and thats it

that is usually the sign of timing to advanced. if you fire the truck up, run it for 2 or 3 minutes and shut it down does it shut down easily? too advanced timing usually acts up worse on hot engine...
