tdi90 Posted March 3, 2008 Report Posted March 3, 2008 I am having cold starting problems with my 99 TDi 90bhp Galaxy (now called Frank :angry2: ) If left over night, its a bugger to start. No excess smoke comes outta the back, and if you pre heat it 4 -5 times it does start. Runs A1 when started, and starts fine for the rest of the day. Its just had a recon engine fitted (2nd one in 6 months) Had a new fuel pump fitted 4 months ago New injector tips 3 months ago Glow plugs have been tested, & are fine No fault codes stored new battery fitted 2 months ago Fuel pump timing has been triple checked and is fine (had that problem when they fitted the new f/pump) I'm at a bit of a loss as to what it could be. Anyone have any ideas please? Quote
NikpV Posted March 3, 2008 Report Posted March 3, 2008 possible air getting into the diesel lines - this may be alleviated by cycling the ignition as the air may be pumped through ?? just a thought Quote
tdi90 Posted March 3, 2008 Author Report Posted March 3, 2008 Cheers for the reply. Complete fuel line system has been replaced, as well as the fuel tank lifter pump. My original main fuel pump was replaced because the return valve was letting the fuel return to the tank, so the car had to bleed itself each time it was started. The starting problems are no where near as bad as they were then, so I'm assuming its not the pump again (although its under warranty so maybe worth a check) Quote
tdi90 Posted March 7, 2008 Author Report Posted March 7, 2008 Problem still not sorted :) . Leave the car for more than 2 hours and it just cranks over and over chucking out thick white ish smoke that stinks of diesel. Starts eventully then sounds as though its not firing on all 4 then catches and holds. Garage I took it too yesterday, reckons its a fault with the pump or injectors, so its off to the garage that fitted the new fuel pump and injectors at thye end of last year. When cranking the engine over for more than a few secs theres a chime that sounds from behind the dash board. Anyone know what it is? Quote
Beyond Help? Posted March 7, 2008 Report Posted March 7, 2008 (edited) That is either the crank sensor of the fuel injector sensor on the No3 injector flagging a fault. If the crank is spinning and that injector is not being opened correctly by the fuel pressure or opening at the right timing interval then it will ping. White smoke says your timing is probably out.
