Hi, I have just bought a 668 Diamante which has been in storage since 2007. It has 8750 km on the clock and looks like that is honest enough. Having charged up the battery and put it onto a power pack to help get  it turned over. I attempted to start it today with some fresh fuel in the tank. It turns over fine but will not fire, I tried som injector/carb cleaner in the air box and it will fire briefly then die.. Suspecting the fuel pump I pulled the throttle bodies off and seem to have fuel pressure to the gallery in the feed line.. The injectors look to be clean and there are no signs of dirty/stale fuel in the lines or in the throttle bodies... any suggestions?

Thanks
Steve
 
Hi Steve,
When you first turn the ignition on you should quite clearly hear the fuel pump start and run ,this should last 2/3 seconds. If you hear nothing then  start your investigation on the basis of fuel pump not working.

Ah, always picked up a couple of fossils for the kids there going through doing the National Rally of Scotland.

Once you sort your bike you'll haver to come along to one of the North of Scotland Laverda Massiv's meetings in Tomintoul if you're still in the area :D
 
its a prick of a job to pull out but the fuel pump will be full of rust varnish and whatever else fuel mutates into after 8 years of sitting, it probably may well be rooted, replacement from a 93 toyota camry is the best option
