As title 2002 V8 M62 with PLG, sometimes struggles to start from cold, as if it has fuel leak back, anyone had a similar issue and cured it ?
New spark plugs
Air filter
I run it on Shell V power when not on LPG

Any assistance appreciated
 
Can you see any live data, I. E engine coolant temp or air temp before initial startup?
 
No live data is meaningful, It's as if I get fuel leak back, but there is no petrol leaking anywhere when running ??
 
Could one or more lpg injectors be leaking? I've had a failure where one injector would stick open and fill the manifold with lpg
 
Lpg is not actually switched on at the main solenoid until warm (5-6 minutes)
No, but there will be pressure in the system until it's switched off. If an injector is leaking slightly, then over a few hours it could dump plenty of lpg into the manifold, it would just sit there with nowhere to go into you try and start up again
 
Coolant sensor misreading a cold engine, air intake sensor can do the same.. But if the live data is not meaningful then working blind deffo isnt.... o_O
