Duel Fuel Only Runs On One Fuel?

i have a 95 f250 4x4 7.5 running on propane or gas. due to gas prices i have been running it on propane, but now that gas has gone down i what to run it on gas but it wont switch over. i flip the switch and the thing just dies. so when the truck isnt running i turn the key on and off to "charge" the fuel system but nothing seems to work... the fuel rails are getting pressure, i check. i also check the fuel reset switch but that was fine. so i got out the test light and started to hunt down wires but i cant find the problem. i dont know if the gas went bad, i dont think so cause i added additives last time i filled up.

can someone help???

Possibly by not using Gas (petrol) something has dried out and is not operating. This used to happen to me in my carby 351 dual feul. I went through a feul pump and a carby kit because they dry out without feul going through them, Im now rebuilding it to run straight gas. What good does the gas (petrol) do anyway?

Check your fuel pressure and filter also check to see if your injectors are working
I am assuming your gasoline line does not have a fuelock (solenoid) that was installed when it was converted

Could it be possible that something went wrong and the injectors have been running dry for awhile and died?
