hi right i,v been there.......i undid the solenoid cable (after testing first with a multimeter to see if 12volt was present ) which it was so removed cable (after diss battery) removed solenoid (caution as you lift it as there is a small..small spring and plunger which may fall out) then if the spring plunger is left behind,,carefully lift both out using a small long nose pliers or tweezers.....put on one side with care,,,,,,then put the top of the solenoid back in place (minus spring and plunger) thus creating an open solenoid situation......then turn over engine.....but remember to put a mole grip or clamp on the fuel pipe between the fuel filter and d.i.pump this is your only means to stop the engine....hope this helps....let us know....regards....chris
