Intermittent starting problems

Hello everyone. I'm a new Jeep owner and love the thing, btw the jeeps not new - 1993 Grand Cherokee 4 litre in line 6 cylinder!! However, its giving me a few problems and hope someone may be able to help.

The Jeep is lhd, Ive bought it to take to France and have had it LPG'd. Didn't have the problem before the conversion, but have a feeling its not just simply a problem with the gas system, although I wonder if it could be affecting something else.

Since then its had a recurring problem of not starting after a drive. It always starts first thing in the morning, but when I take it for a drive, typically, I may stop the car either for a few minutes or an hour or so, then when I come to start the car it just turns over and wont start if I leave it for an hour or so -it will start????
This doesn't happen every time but quite often.

The guy that fitted the lpg has been a great help -and is pretty sure it's flooding, but we cant work out why. I've fitted a new idle air control valve, seems to help a bit but prob stil there.

Other potential culprits seem to be intake air sensor, map sensor or coolant sensor.

Has anyone hit the same problem? I don't mind buying the bits but don't want to randomnly buy parts without being sure of the cause.

Still love the car - Have a silly question too, can anyone tell me why its called a "Limited" on the reg doc, but got "Laredo" on the car.

Any suggestions welcome
