I have a 2007 swift bolero fiat ducato 2.3 td 130 multijet Motorhome. I ave been having a terrible time starting it and have put new glow plugs in, new glow plug relay and yet the problem persists. I started this evening (eventually !!!) after about 5 minutes of continual cranking of the engine. In total I probably cranked the engine 5+ times and then it fired up. I always depress the clutch and do not pump the accelerator, it then for now apparent reason starts. I have noticed, as before, the glow plug light only stays on for 1 to 2 seconds and is the same before I changed the glow plugs and relay. Once the engine started I noticed a sign (a car with a padlock thru it) on the instrument panel remained on thru out the 30 minutes I kept the engine running. HELP , WHY IS MY MOTORHOME SO DIFFICULT TO START, I am so fed up with it that I nearly always flatten the battery. HELP, anyone.
