Er, starting trouble...

<< < (3/3)

DiscoCWK:
I've heard a lot of disco starting problems are caused by dry joints/burnt out tracks on the 'spider' unit, which has control over the stop solenoid (fuel pump). Is there someone with more knowledge out there who can shed some light on 'spider' symptoms!

beatmasterdave:
howdy!
im no mechanic, had to ask the same question  :oops: because i had same problem, turned out to be glow plugs, i think they might be about £10each give or take.
good luck

Tyke:
Fuel supply, compression or electrical . . . . . a systematic check of all these areas and only make one change at a time and you should eventually single out the problem.

If you're not confident about doing it take it to someone who is, it shouldn't be rocket science to sort it out. Direct injection diesel engines are relatively simple beasts that respond to relatively simple reasoning.


For my money, I'd check the fuel supply and lift pump, then swap out the glow plugs for a set of known good ones . . . . if that don't sort it then a compression check will indicate the condition of the valves, rings, bores, sealing faces etc.

If that turns out to be the problem, it's beyond the scope of the average 'home mechanic'. If it's electrical, it can only really be the supply to the glow plugs, the stop solenoid or the immobiliser . . . . but it will probably need someone with the right tackle to diagnose any problem.


Oh yeah . . . it might sound silly as the motor is cranking over on the key from what you describe . . . . but is the battery really up to scratch? . . . . . Tdi's need a good fast spin over sometimes.


Good Luck  :wink:
