Right straight to the point, have a 2011 1.7 diesel corsa with a rake of problems but the main one is that it struggles to start when it's been sitting for over a day. When you turn the ignition on the fuel pump keeps going for over 5 minutes, and if u try to start the car before it fully primes white smokes come out and she splutters and never starts, if u wait the full 5 minutes and then crank her she splutters for a bit but after a few does start. If you leave the car runnng for a little while or even drive it around for 15mins or so, shell start perfect for the rest of the day, but next day starting back to the very same. If you start the car in the morning and only run it for a few seconds, and leave it for a little while it struggles to start again. One of the glow plugs is snapped off in the head but it was like that a good while before this issue began, so I'm a bit stumped. Any ideas are welcome!
