Have noticed lately that when the engine is warm it wont switch to lpg, it simply stalls. I like to take the big long hills to my place on petrol.
This issue does not present itself when starting as the impco system I have fitted will start on petrol then automatically switch to LPG once you bump the throttle past 1500rmp.
I have been thinking that it may the gas supply solenoid on the intake before the throttle body. How can I check this is opening??? Multi meter on the pins will only tell me if its getting signal.
Could it also be the tank solenoid? do these solenoids play up??

If I pull over for five minutes and let it cool down the car will switch to either fuel, no probs.
