Where to begin here, did you check that when you switch the ignition on that you are getting power to the glow plugs if not this may lead to a more sinister fault. What is strange is if the stop light stays on I would have thought that a code would be there. I agree with you regards if the glow plugs were faulty as long as you have reasonable compression it will still fire as its not that cold yet.
You may have a long road here best of luck

 

Yes checked for power to the glow plugs when turned the ignition, sufficient power is getting to each one, seems very on and off as once i get it fired the first time in the day, it will run all day, then fail the following morning. After i replaced the glow plugs it ran consistently for 3 weeks, because its failed again it tells me it may not be that, thank you for your help.

 

When I had starting issues with mine it turned out to be a cam sensor and yes they can be intermittent as they are fairly cheap its worth trying bit of a pain to change though.

 

this may be worth a try..... before you start the engine just give the priming bulb a few squeezes until its hard and the pump is fully primed. I had a dci clio that did the same and it turned out to be a leak off pipe that was allowing air into the system and allowing the fuel to drain back into the tank overnight. no leaks were apparent and it was a bit of a mystery for a while.... good luck

 

I’d suggest that you check the cam position sensor, they have a history of failing on that engine.
Our Scenic has the same engine and its fine first thing, but often takes 3-4 tries when its warmed up.

Also check the leak off pipes on the injectors aren’t leaking / letting air in. Look at the clear low pressure pipes into the fuel pump when trying to start it, are there any bubbles going through it?
It could be glow plugs, you can take them out and put 12v across them to see if they work, but read up on what you’re supposed to do first!

Please be wary of putting 12v direct on to glow plugs. Depending on their rating, some are rated at only 6 volts and putting 12v on them direct can burn them out in seconds. If memory serves I think the plugs on that vintage Kangoo is 11v so they should be ok for a couple of seconds but I would still play it safe and connect them to engine wiring too check them. that way you will test them at the correct voltage and no harm will come to them.

 

And good luck getting 11 volt glow plugs
IF you have to settle on 12 volt glow plugs, you will need a 12 volt glow plug relay ( Tbay only sell 12 volt glow plug relay )
DONT go to the main agents for 1 They will sell you a 11 volt glow plug relay
