Fuel draining into tank? Citroen ZX TD - Shaz {p}
I have a problem with my 94 citroen zx td when starting from cold.

The engine cranks for about 10-15 seconds before catching. After this it starts fine all day.

This problem has started to occurr after I had the head rebuilt and replaced after a cambelt snap. The mechanic did take the engine out to do the job - due to restricted access in the bay.

The car was a first time starter before this.

Apart from this the car drives fine. The glow plugs are new - original Beru ones- so it is not that. Whilst the head was off the mechanic checked the injecters - they were fine also.

If I bleed the fuel system by pumping the bulb about 10-12 times then the car starts fine - straight away.

I think that the fuel is in the line is draining back into the tank. How can I rectify this?

What else could be causing this?

I thought I\'d get more response this way - by covering both forum\'s - and it seems I have.

Strategic errrm.... forum posting.

I am currently tracing the air leak. Fuel filter housing seems ok.

Looking at the primer next.

Just to give feedback:

Finally got round to looking at the problem - would have gt garage to do it- but quicker to do it myself.

It was the return or spill lines on the injectors. - Had very minor splits - only one was leaking - the others were not but were split at the ends. Changed these - and result - started first time instantly, just like it used to.

Thanks for the help. Was getting tired of pumping that primer - had to pump it about twenty-five times just to get it started in the mornings!!

I ended changing all the spill lines - Citroen dealer wanted about £10 - for the pipe!! Got it from local GSF for £2.00 (1 metre)!
