1.6td jx won't start

[JJJackson]

Hi 1.6td jx has always started on the button, now won't start. Changed the fuel filter and a small section of pipe connecting filter to fuel inlet pipe as could see air.

Next step to change thermovalve on top of filter, any other ideas? Also what mm is the fuel lines?

Thanks

Check the return/ bleed off piping. It's the black cotton covered tubing that goes from injector to injector.
It perishes and lets air in.

Thanks.. another thing to look at

I used to change it every year.

New fuel filter and pipe between filter and pump changed. Cracked pipe from diesel tank changed. Appears to be no air in system now, but won't start without being towed, literally will start after towing 10ft and runs lovely. Glow plugs next, then after that abit stuck, any other ideas.

Injector pipe work also lucks ok.

Very likely to be glow plugs, are you getting black smoke when cranking? If so the fuel is probably OK.

Also check the glow plug fuse.

[JJJackson]

Would the cold start light come on still if the fuse wasn't working ?

[Titus A Duxass]

Yes.

Found the fault a broken wire to the glow plugs - thanks for the assistance.

[Titus A Duxass]

Good stuff.

The odd thing was the plastic sheathing was intact but the wire broken inside !!!

That's a normal failure mode for wiring, the inner conductor work hardens but the insulation stays flexible.
