GU 4.2 MISSING

mine's done this a couple of times, but only seems to be when its really cold, i.e. when i'm at the snow.

The glow plug timers can give problems but with the patrol you can over ride them.
Once the light goes out and you here the timer click out, turn the key towards the start postition very slowly and you will here the glow plugs click back in. You can hold them in that position as long as you like. An extra 10 seconds in the cold usually makes all the difference.

Run a couple of tanks of Good Quality injector cleaner through, you'll probally find you've got a leaky injector seal and it's letting fuel leak in overnight casuing a miss on startup and heaps of smoke.

I had this problem with my Rocky, my mechanic at the time reaplced the glow plugs and it solved the problem for about 1 week, then he told me to either spend $$$ and replace the injectors or run some cleaner through it. I opted for the injector cleaner, never had the problem again!

hey guppo, nEVER HAD THIS PROBLEM Because I have FITCH fitted ??????
For the dissbelievers as I stated you will all become aware some day. I feel so sorry for the money wasters on fuel yet you all help the fuel companys with their rip offs except the fitch users who have sence. COP this lot BAGGERS,,,,,,,

I'm pretty sure this was covered a while back and the problem was solved by using glow plugs specifically intended for colder climates (NZ) Do a search of the archives and your questions may be answered. In really cold conditions I actually turn the key on twice to help the engine fire.
