Thanks Shane,I have to rely on others at the moment as my joints are playing up.My son wants to fit grease nipples in various parts of my body to make me more mobile.I have arranged for an auto electrician to come either Wednesday or Thursday and according to the AA man he should be able to sort it out.He played around with the glow plug relays and got it started every time,so after he left,I drove it down to our fuel tank filled it and backed it into the shed again,turned it off and then it wouldn't start.Got it going once more later in the day but will leave it to the expert.
