rover 75 diesel won't start

[Paradigm Bill]

I have a Rover 75 2002 diesel (BMW engine) which will not start. About two months ago I was driving home when the car appeared to run out of fuel (at quarter full). Luckily I was 50ys from a fuel stn, so I put 5 litres in, car started and got me home, so I thought it was a faulty fuel guage. Two weeks ago I let the fuel drop below one quarter full, but this time not close to a garage for fuel so I tried to start it by turning it over a few more times than the first time it broke down - no joy! So I towed the car home and put 10 litres of fuel in - still didn't start. I went online 'in tank pump fault' i checked running of both pumps only under bonnet pump worked. Spent £300+ on new pump and fitted successfully - pump was running, both working fine. Before I cranked car to start I charged the battery overnight as it was low - I connected the battery and let it stand for 10 minutes to allow immobiliser to settle in; I disconnected under bonnet pump and bled air out to fuel filter and then to main pump so not to stress out UBP. I tried to start the car but no joy; I undid No.1 injector pipe - fuel came out - so there is fuel to injectors - Please can anyone help, have I incurred a fault by battery running low, engine icon non-start is not on when cranking. Is the key fob immobilisier at fault due to when battery low and trying to start, or is it something I have done... I am 35 years a motor mechanic but have no equipment past basic spanners etc.. also I am not in the UK at present, in Italy where you can't buy easy Start!!!!!! HELP if Possible Please

Is the rev counter needle bouncing at all, when you crank it over?

Hi Harry, Thanks for the reply... I have just cranked the engine and the needle doesnt move.. no bounce at all Bill

Any flammable spray will do to start a diesel engine, as a temp measure try some hair spray. Make sure you comb it first though.. heh heh...

In that case, your cam or crank sensor has failed (can't remember which), but it is a well known syptom. It should start and then run fine with EasyStart (or hairspray). Spray it directly into the EGR, after removing the large pipe.

The rev counter signal comes from the crank sensor, so if you aren't seeing any needle movement at all when cranking could be either the sensor itself or the wiring.

The crank sensor also provides the timing information to the ECU for the fuel injectors.

The cam sensor is only used by the ECU to synchronise the cam position at start up and once that is done it ignores the cam sensor until the next start up.

Without T4,try this:

And test your injector's leakback.

Good luck

This was the advice I was given by FrenchMike. Simple tests with only a simple volt meter.

Sadly they have proved inconclusive with my similiar fault of non starting (all in another thread)

Hi Harry, It started briefly with the spray, but will not run. Bill

No fuel getting through or a large leak back through injector(s), plus a failed crank sensor.
