After driving on LPG, engine cannot run again for a while
I have mazda 626 lx 1998 lpg/gasoline. Initial ignition is always on gasoline and after start I can switch to LPG. Problem started recently when I drive on LPG and off the engine. After that I am not able to run it again for a while. This is usually happened during summer time. Seems to me that need to wait some relay to be opened and gasoline come to the engine. Anyone can help me with advise
