to test glow plugs
remove the electrical connectors
tast resistence between glow plug terminal and glow plug body...approx 0.2ohms

with electrics connected, cold engine, ign on, plugs should power up for approx 8 secs
cold engine, wait for glow light to extinguish, start engine and let idle, plugs should power up for approx 30 secs.

but to be honest, unless you know the history of plugs, may pay to change them anyway
originally you stated all was fine once started...so..

injector coding...if done in right sequence, did you get numbers from injectors themselves, or the sticker...if it was the sticker, you may find injectors have been changed/swapped about in past...would double check those codes on the injector themselves.
would blank that egr off and fit a quality filter and make sure all is bled properly..plus clear any stored codes


once that is all done, then if you still have problems, see what code/s are flagging up

I got the codes from the injectors. Where exactly are the glow plugs?

 

cheers guys

Right..

1) EGR and Inlet manifold cleaned and blanked.

2) Filter changed for a Bosch filter

3) Camshaft sensor change

 

Still won't start and the problems seems worse, like if left for a few hours it won't start, whereas before it would!

 

Are glow plugs used v=even when the engine is warm?

Weird-i changed EGR& cleaned inlet manifold. I have a low signal for camshaft sensor. Away to fit another 1 tomorrow hopefully. Whys every1 change glow-plugs on mondeo's? I mean theyre not used apart from when its really cold? Wouldnt have thought it'd make a lotta difference. Was your camshaft sensor low as well?

technology has changed, granted the plugs are designed to start a cold engine, but in modern cars it pays to think of them as part of complicated self tuning system..if any one of those parts fail, it can lead to other parts trying to compensate for that failure.

 

think that makes sense :)

 

that is why plugs can cause running problems even if engine is warm, can even put engine into limp mode. and yes, glow plugs still power up on a warm engine.

 

those glow plugs need to be at least tested, but tbh, if you dont know the history, just change them
