Try shoving 12V down the power wire to the gas tank and see if this operates the solenoid. Sometimes the anti-spike diode in the solenoids develop a short and a decent current surge just blows up the diode. The coil part still works fine after that.

Yea tried that mate still nothing, they both click on but seems like there is no gas?

Another possibility is that the plunger inside the solenoid valve at the tank has a failed rubber seat. Turn off the tap firmly, undo the 8mm hex bolt on the coil and remove the coil, undo the 17mm hex brass barrel nut that contains the plunger. The rubber seat may have a hole in it cut by the brass seat it rests on. There will be a tiny rubber slug sitting there blocking the flow if this is the case. Don't refit the plunger to the solenoid and don't damage the o-ring as you assemble the valve barrel. This is a temporary fix to get you going. The plunger is exactly the same as many other gas valves so easy enough to replace so it remains safe. Use some soapy water for leak checking and of course no naked flame anywhere nearby.

Or there is the possibility someone turned off the tap while you weren't looking...

Haha! No one turned the tap off, I'll give that a go today and let you know how it goes.

YOU BEE UTEY!!!!!!!!!! so did what you said but still didn't start buuuuuutttttt as I put it back together I noticed that the solenoid didn't move around like the one in the bonnet so I checked the nut on the top of the one in the bonnet which a earth is attached to and I could undo it with my fingers I tightened the bugger up and vroooooom she sprang to life!!!!! Very happy now thank you so much for your help!! I've also re soldered all connections and put heat wrap on them too and hopefully this weekend I will be replacing the crappy inline fuses with better water proof ones.
