Starting issues 3.0l CRD

[Gregsway]

I have installed the new primer bulb and the fuel bleed back problem problem seems to be better but hasn't stopped. I changed the last fuel line leading to the engine with clear tube and no bubbles came through once the initial air had cleared (from changing the line)and leaving it standing for an hour or two no bubbles formed in that section. But the fuel still bled back on the other side of the filter.

My wife needed the car so I had to stop and put it back together.
So tomorrow i will replace the rest of the lines with clear tube and see what happens.

3 Questions if anyone can help?

Is there a return valve anywhere in the fuel line?
How long should it take for the car to start when working normally? At the moment it is taking around 4 seconds fairly consistently. That seems 2 seconds to slow to me.
Could it be the fuel pump relay? Not sure if its on the left or right in my car?

Thanks again!

Am I correct that fuel is sucked into the engine rather than it being pushed out by a pump from the tank? Just reading some threads and getting myself confused a bit and wanted to make sure.

I had the same starting issues after sometime being up at the snow.

My mechanic had a look at it, checked the glow plugs,they were fine, checked the battery (was only 4 weeks old) and it was fine, checked the primer and found that the hose clips which come as standard were crap and replaced all of them and now I have had no issues.

My 2 cents.

Thanks Crazyenough I bought new fuel lines today so will put them in tomorrow! I have allready replaced all the clamps.

Sorry I havent read from the first post. Have you fitted a genuine fuel filter?

Hi Schanmala - yes I bought a genuine filter

Fuel isn't sucked into the engine as such with the CRD, it is injected in under high pressure.

Diesel is pumped around at up to 160 mPa, and excess fuel not used in the injectors is returned to the tank....

Thanks Guys - I thought I should update you on my progress.

I bought a new battery 760 CCA which has improved things, the problem is not as bad as it use to be, the car now starts in 3 seconds, which is slow but not too bad. Its been 7000kms since the problem started. If anything it has gotten better and now stayed the same for 2000km. I plan to put a new fuel filter in this weekend and see if it improves things.

I will then see if it's time to get a mechanic to look at it. i have tried pressurizing the fuel lines and found no leaks.

Will let you know when I solve the issue properly

Make sure to wipe some fresh diesel on the "O" ring or any seals the Cr filter may have

there is a small filter gauze on the fuel pump where the fuel line goes in
undo the connection and is in behind could be partially blocked
