Mercedes Vito 110cdi - Starting problems with Vito 110cdi van - John Britcher

After filling up with fuel at Sainsburys my van took longer to start after stopped

The problem continued to get worse and was a problem starting the next 3 times and then wil not start at all

My friend came round and took a look and removed the air manifold from the air filter and sprayed some starter aid in fro,m a tin then the van started soon as key was turned but when switched off after about 15 mins of running it again would not start and the only way to start this is to do the same as he done

I wonder if the problem is electrical or maybe just due to dirty fuel

When I was replacing the air filter as a way of eliminating possible problems I caught the back of the fuel pressure sensor and the nipple on the back seemed to just easily snap off making me wonder if the problem may have been this part being cracked before as it seemed to break of at the smallest of touches hav enow ordered a new replacement part anyway

I also bought a new fuel filter which I intend having fitted soon as possible

The thing I wish to know is why it only starts with the can of starting spray

Any help would be thankfully received

John

these suffer really badly with injectors casuing loss of fuel pressure and failure to start. I would suggest you find a diesel specialist who can carry out a leak back test.

Bewarned these injectors are wallet bending !

may be worth trying some "Comma " Diesel " Injector magic" from Halfords in a red tall bottle ,through first, in case you have a sticking nozzel. Occassionally works very well.

I trust you did fill with diesel and not petrol ? that make sthem a b***** to start !

For this particular problem i would be inclined to start by checking fuel rail pressure sensor theres a small green o ring that goes on these (common fault) when they go faulty you lose rail pressure. As far as i can remember you can get these at the dealers.Hth Regards Mickeybo
