re- diesel ford focus

Hi, having probs starting my V reg ford focus, i`ve changed glow plugs, i`ve
got power to the glow plugs when its cold, but when its warm i`ve got no
power to the glow plugs. can you help? But if i leave it about 12 hrs it will
start up normal.

 

Ahem, read the title of the newsgroup you're posting to!

This has been a public service announcement for the mentally retarded.

 

Ok so i got it wrong, do you have to be so rude????
And dont call yourself mentally retarded even though i think you are.....

 

Dont matter what car it is i will try and help..Check your relay.i
think your find the glow plugs dont have power after the engine has
started.or if they do it is only for a very short time.

 

Ok thanks, I have swapped the relays around & it still dont seem to do it,
there`s just no power to the glow plugs when engines been running for a few
minutes.
Do you know any other websites that could help us???
thanks again mate.

 

I think that is normal.relay cuts out after engine has started. so
there will be no power at glow plugs.this will help.
The plugs are eletrically-operated before and during start-up when
engine is cold.Electrical feed to the glow plugs is controlled by a
relay/timer unit.the glow plugs provide a "post-heating" function
whereby the glow plugs remain switched on for a period after the engine
has started,Once the starter has been switched off, the glow plugs
begin a 3-minute "post-heating" cycle.the operation of the plugs cannot
be cancelled for the first 15 seconds,

 

Ooh that hurt. Hang on... my brother's bigger than your brother. Is that a
grown up enough response?
