Recently my mk1 vrs se wouldn't start. No code errors, battery and alternator OK.

I changed the fuel lift pump, problem still there ! After a squirt of "easy start" car started and runs fine.

Any ideas what could cause the starting issue.

Thanks in advance.

Glowplug problem. Check them with a multimeter.

Shouldn’t be a problem with glowplugs in the weather we are having at the moment.They are only needed when the ambient is around 5 deg.C.or colder.

Thanks,

The problem is intermittent, full diagnostic shows no errors at all.

Glowplugs is a cheap job so I'll try that, they are the original  ones.

Fuel pump was an expensive attempt at a fix !

Some diagnostic tools don’t some or all errors, even if they are present. 

Update.

Fuel pump and glow plugs done.

Started and ran well yesterday.

This morning problem starting again, it turns over but wont fire.

Several attempts then ok !

Any ideas.

Thanks 

Sounds a lot like fuel running back overnight.Try a non-return valve on the line from tank to filter ?

Thanks, Would you know what size valve tm use.

No sorry I have no idea.

Any thoughts on the tandem pump causing this problem

Update.

Injector seals were the problem.
