Customer Question

I have a 4.6 v8 range Rover with a multipoint lpg system by Prinz. It's started being reluctant to turn onto the LPG system despite being warm... is there some simple servicing that I can do, as a relatively competent amateur spanner wielder? This system is now 10 years old, the last 3 years in my ownership. I have installed 3 single-point LPG systems myself on Classic Rangies in the past, all successfully done! Any help greatly appreciated, as I'm miles from any help...!

Hello

I'd start by adding a bottle of injector cleaner to the gas tank , as this will help with sticking valves

then its usually a case of checking for any leakage, change the LPG filter and run a computer diagnostics.

there's usually a valve lubrication system too so check that its top up tank is at the correct level, Add around one liter of lubricant for 10,000 kilometers
