2.0 Hdi Failing To Start. Turns Over Fine

[matpj]

I occassionally put 15 litres of vege oil in my 2.0 HDi

 

has been running fine on it.

Put some in last night just after stopping. Had about a quarter of a tank of diesel still in it.

went to start the car afterwards and it did not fire.

 

not even the slightest splutter.

its either a big coincidence, or the vege oil has caused it.

 

I would have though that the diesel still in the pipes would have at least made the engine fire and then die, but there was nothing.

 

now I need to try and work out what the problem is!

 

is it easy to test/replace the low-pressure fuel pump in the tank?

are there any other things I need to check?

it might be worth cleaning the ends of the injectors and glow plugs they could be greased up with chip fat

are the glow plugs easy to get to?

I dont own a Haynes manual.

 

The oil I used was straight from the shelf so clean and particle free.

 

is it possible to flood a modern diesel engine?

I was cranking the engine for some time (and so was the AA man when he came to my rescue)

Hi, I have an 'X' Reg Xsara 5 Door 2ltr HDI, When I bought this car, i suffered a number of Engine failure-to-start problems that required the car to be bought home on the back of a truck, usually, when I tried the car the next day it would run as normal, usually for a number of weeks before not starting again (usually miles away from civilisation).

 

I eventually discovered that a connection between the large Relay on the Bulkhead under the Bonnet (blue wire) and the Fuse box was breaking down, this was effectively cutting power to the Fuel Pump. I simply ran a wire in parelle to the existing wiring between the relay and the fuse-box, result, no more problems.

 

I discovered on a forum (like this one) that somepeople were wiring their fuel pumps directly to the Battery to get round this problem, or (as I did whilst sorting out this problem) making a lead that could be plugged into the Cigar lighter socket to provide power to the pump. Both these solutions are good for getting out of trouble, but if your car has the same fault as mine, i feel the neater fix is to bypass the problem as I did above.

 

Good Luck

get some one to bang on the bottom of the fuel tank while you crank it over. if it starts the low pressure pump is on its way out.
