Diesel pump?

[ukbob]

Hi everyone I have a 99 Terrano that will not start unless I give her a squirt of easy start once started she sometimes ticks over but not others.If it cuts out it will restart if I try straight away but if I leave it a minute it will not restart.I have cleaned the maf have checked the filter in the top of the pump but already removed.When the ignition is on there is a whirring noise from the diesel pump which is constant.I have also fitted a new filter.
Any ideas of what this might be?
Thanks Bob.
It does have fuel at the injectors.
No engine management light is on when it is running!

Have you checked glow plugs and solenoid wires?

Have you checked glow plugs and solenoid wires?

I have taken all the wiring plugs apart and used electrical cleaner and cannot see any breaks in the wiring.
The glow plug light works and the glow plug relay clicks on and off.
I would of thought if it had glow plug problems it would still start when warm but after a minute it will no longer start.

Yeh but is there any electrickery coming out ?
The solenoid beside the battery sometimes fail, as do the cables . Even when warm these engines need a bit of heat and the plugs stay on for a little while after start too.

Simple answer I don't know I will check it tomorrow and get back to you.
My 96 one never gives any trouble.

how many miles has it done, is the performance up to scratch, it sounds more like poor compression to me, Rick

Its only done a 100k when it runs it doesn't smoke although when first started it misses a bit but if you throttle it it clears and picks up fine.It still pulls like a train if you can keep it running.LOL

The missing could be down to one or two glow plugs not working, you can check them without removing them with a resistance meter they should read very low ohms cant remember the figure but around 4 or 5 ohms if not working will read open or high ohms, if you have not got a meter take a wire from the batter + and hold it on each plug in turn it should give a flash then hold it for about 20 seconds it will now be glowing inside and flash it again if it still flashes then it is probably OK do each one in turn, and you will have to remove the links to do this, Rick

Thanks rick I will go through them tomorrow the strange thing is I had it running and starting fine earlier I drove it around it was restarting and ticking over then I revved it turned it off then it wouldn't start again.Fired it up on a squirt of easy start and it decided it would no longer tick over.Plus the throttle response now takes ages to pick up.

As makeitfit says, relay could be playing about, Rick

Where did you squirt the old spray ? As if it's in the air box the MAF may be in need of a clean again maybe :nenau

I had this problem with a Vectra, the RAC could start it with WD 40.

If it was left for an hour it would still start, but any longer and it needed the "fix" again...


What it was, is that fuel was running back to the tank, forming an air lock, the starter motor didn't have the speed to pump the fuel through.

So it could be air getting in.

1 Did you have a new fuel filter recently?
2 the spill pipes on the injectors could be letting air in.
3 It may be possible that the fuel lines are corroded from the tank to the filter. Or even blocked fuel lines.


Not sure what you mean about the fuel pump whirring when the ignition is on, these motors rely on the diesel injection pump to "suck" the fuel from the tank.
As far as I am aware there is no electric fuel pump. :nenau

Hope this helps,
best regards, Rustic

Thanks Rustic it could be fuel lines but there is a whirring noise at the diesel pump as soon as the ignition is turned on.

As Rustic says there is no electric pump in or on the fuel pump (unless one has been added to try and cure a previous fault) so other than that I do not know where your noise is coming from, have a good look at the fuel lines to see if anything has been added, Rick

No fuel pump added Rick i wonder if the advance solenoid is sticking in the pump.

Quick update there is certainly something wrong in the pump and I have had it running again and it revved out on its own then would not start again would this likely be the electronics on the top of the pump as its not showing an engine management light?
I do have plenty of power to the heater plugs by the way.

To help others on this site, do you know the make of the pump, they are often Bosch, but may be something else.:nenau

"No fuel pump added Rick i wonder if the advance solenoid is sticking in the pump."
Do not think thats the problem. According to my fault codes thats what i have, the symptoms being:-
poor cold starting(similar to yours)
once started flat spots and mil light coming on at pretty set rpm`s
a reduced max speed
oh and the mil light clears on taking foot of throttle.

 

[BIGSEAN]

Forgot to mention, in all other respects it does sound like leaky fuel lines, look for a damp patch near drivers side rear wheel chassis rail.

hi, mate sounds like the problem i had with miine it does have a timeing moter inside [not sure if thats the right term for it] all sorts of things can affect the system mine had a habit of not restarting in a particuler asda that had a system that sent a signal to the trollys to lock the wheels it would turn over all day but no fuel at injectors, today got it running after fitting a mech pump fires up soon as i press the button, bit of inj knock but a bit of fine tuning will sort it, the elec pump i took out was a bosch but ive seen zexel elec pumps on ebay, [just thought may be mine just prefared tesco!] anyway you,ll get lots of help from the gang on here . just curios but did your last one have a mech pump.
