yep points to the pump or the connections to it, have a very good check of the plug onto the top of the tank first, if not remove cover , then unbolt tank cover / pump assembly in boot / through seats, again have a good look at the connections, on mine someone had fitted an uprated pump and the plug wasn`t quite right, you could also try the pump on a seperate battery,
be carefull with any form of spark when you have the "roof" off the tank, do not reconect the pump with it all open with the ignition switched on, and I would suggest a "mate " with a co2 / powder fire extinguisher about just in case,
