Re: 1.9 Mulitjet 105 Glow Plugs

Thanks for your reply
How can l test the pressure and what tool will l need?

I searched online and it showed how to test the fuel rail pressure sensor on a 1.3 MJ Doblo, but couldn't find one for the 1.9 MJ

The glow plug warning symbol flashes after starting for around five seconds then goes off if it helps


Cheers

Re: 1.9 Mulitjet 105 Glow Plugs

I bit the bullet and changed the remaining two glow plugs, as l had bought fur anyway

She starts much better now, so it looks like all the plugs needed changing.

I am a bit fingers crossed, wondering if it was underperforming plugs and a n other fault, so i'll get on with getting a Multiecuscan as you suggested.

Thanks for all replies and help

Re: 1.9 Mulitjet 105 Glow Plugs

Update on the above

The car does start better than before the glow plugs were changed, but it still has a problem with the first start of the day

The engine cranking speed is noticeably slower first thing, worse in the cold and troublesome in the warmer mornings. It turns slow then nearly stops, continuing that sequence anti it finally starts, bit like a petrol engine when the ignition timing is off if that helps

It dos have a new battery, but the issue of slow cranking is about the same, so the old battery was serviceable

Once the first start is done, during the day it'll start great, the cranking speed is probably twice as fast and sounds "free" although l can't measure it. It runs good too, no issues there.

Any suggestions what the cause might be or what l can do to chck it. I have an Maxiscan 309 which isn't showing any fault codes

Thanks as usual for your time and assistance

Re: 1.9 Mulitjet 105 Glow Plugs
