1.9 JTDM trouble starting - Please help

Sorry. Let me clarify.

The starter motor was replaced as it was turned over slowly in occasions so this needed doing anyway but was hoping it was causing the other issue.

Spoke to me basic again and I got it wrong. He said the fuel pump should be ok. And suspects first place to check is replacing the cam shaft sensor.

Will test cranking pressure tonight just to double check
 
Ok. Stuck now!

Changed starter motor
Tested battery
Injectors tested and ok
Fuel pressure good on cranking
No fault codes
Runs perfect once started
Intermittent starting problem, Just takes around 10 seconds to start, turns over fine but struggles to pick up

Mechanic said possible a sensor.

I was thinking camshaft sensor or crankshaft sensor?

What's everyone's opinions?
 
They were replaced in 2015 and wouldn't it throw up an error code?

Car continues to have trouble starting even after 30 mins of driving.

Would you still think it's worth changing them?
 
Thanks

It's not that then as I used jump leads yesterday to see if it made any difference and it didn't.
 
Nearly the same. Doblo multijet 1.9 120hp. Very new to me. Starts every time but first try takes a few turn overs. Better if I turn on the power but don't start the car wait for all the lights to go out on the dash. If I just turn the key and let it struggle I get black smoke on startup, after that it's fine and will start again. I also get very brief lumpyness when coming off the gas after smooth driving i.e on a dual carriageway but not always.
 
Diesel engines require the assistance of heaters - Glow Plugs to start correctly and cleanly. Even more so in winter.

You have to wait till the Glow Plug heater coil lamp on the dash goes out before attempting to start.

If you have problems after the light has gone out then this often means that one or more glow plugs have failed. Even the loss of one can really upset starting.
 
Thanks, I'm hoping it's glow plugs/ fuel filter.

But the glow plugs don't look easy to get out
 
If its the multijet and is same as mine (it should be but less hp, i have 150 model)... then they are easy to remove... just buy a laser line bendy deep socket...

Spray them with plusgas or a releasing fluid then be gentle... did mine in less than 20mins.

Dont tighten them too much, just hand tighten them and gently nip them, they only need 8nm torque and no more than 10nm torque.
 
You can test if a glow plug is working or not.

The ideal way is to use a current meter (ideal is a clamp on meter) to measure the current into each of the glow plugs. Typically this will be 10A+ per plug.

The other way is to measure the resistance of the plugs. This will be low at 1 ohm or less.

You may find this Beru publication of value: http://beru.federalmogul.com/sites/default/files/ti_04_gb_2014_fm.pdf

When I changed my glow plugs they were not that bad to get out. As I recall a little wire and tube moving is required for some but nothing that excessive. A CAUTIONARY note would be use a snug/correct fitting socket 'square on' AND DO NOT FORCE!

Stuck hard to remove glow plugs are not that common but using force will certainly result in twisting the head off and then you are in expensive trouble.

If you need to replace one then you might as well do all four.

Lastly, if you do your own servicing then it is always a plan to periodically remove the glow plugs re-lube the theads (with Moly or Copper grease) and put back just a little over finger/wrist tight or look up the correct torque figure.
 
Use this on the new plugs:

And use carburetorspray if the old plugs are stuck because of carbon build-up on the lower tread.
Carburetorspray will disolve any build up dirt fast...
