sounds expensive part 2, rover 75 cdt 02

Timbo.P6 · 3rd May 2009, 18:28

Right just wanted to let people know all the things we,ve tried so far on the car to try to resolve the situation on our rover 75 cdt 2002.with no joy

1) Injectors have been cleaned profesionally, one was down but working now
2) in-tank fuel pump changed, but 2nd hand one was replacement
3)crank sensor changed
4) cam sensor changed
5)we.ve swapped battery over with Russ one, no joy
6) swapped fuel filter
7)disconnected all sensors we could reach, sprayed them with contact cleaner,then put them back together
8) took ecu out no obvious problems there, no corrosion or anything,
9) the emergency cut off fuel switch under the glove box was fine

It cant be the key or immobiliser as the starter motor works,
The car ran for about 5 secs at each turn of the key , but then just stops

So any more suggestions would be greatly appreciated, thanks, Tim

As you've pulled the fuel side to bits with no joy, try the air side of things. look for collapsed pipes, beathers or blocakages.

So is it now starting but just not running then ?

we get between 2-5 seconds each time we start her up, then its like someone has just hit the fuel cut off switch, no idiot lights coming on, its very frustrating

Didn't notice you'd started another thread just posted on other one

So have removed it and re posted here for continuity.

Jim suggested having another thread with everything we,ve done so far on it, it might help,
thanks a lot for today, hope you didnt get into too much bother

on older mems equiped rovers that run for a few seconds usualy indicates an immobiliser problem this is most prevailant on turbo conversions in which the immobiliser has not been removed or de-activated within the donor ecu.. as im new to 75's i have no idea wether you can re-code the key to the alarm circuit but you can re sync older rovers where the immob and key have become un sync'd

Stupid question maybe but you have tried the fuel cut off switch I assume (think we have one

don't we ! ?)
By fuel filter assume you refer to the tank module in L/H side of tank (sorry didn't notice your model)

Sorry, jumped the gun. Went back and had another look at your first post

Tatts came round today, with his fault finder but it didnt show up anything

He told us about the good garage scheme, you put your postcode in, and it brings up garages that specialise in your car, in your area,
going to phone the one thats 10 miles away from us, see if they have T4 , then try to get the car there,if they do have that diagnostic machine, it says they deal mainly with landrover so not holding out much hope,

Tims just tried the car,and today we are back to square one, she doesnt want to start at all,
now I want to cry,

Anyone wanting a non running rover 75 connoiseur se cdt, just name your price,!!!! I,m sure Tim wont be TOO upset if I sell it

I don't know the 'ins and outs' of the diesels, but sometimes on car injection systems there is a check that the engine is running that the ECU has to detect in order to keep the engine running, and this is bypassed during the starting routine, which can be detected by power being supplied to the starter motor. When no power is supplied the check on whether the engine is running or not is applied. If the sensor or whatever is giving an indication that the engine is not running the fuel supply is cut off. So your engine starts but as soon as it starts and the starter motor is shut down, the engine stops within seconds.

This was the case on an old Jaguar XJ6 I once had which had an early fuel injection system, (Bosch L-Jetronic) and analogue system. The mass airflow box which had a flat valve that moved as the air entered the inlet manifold and had a pair of contacts in it that were closed by the flap once the air started passing and this kept the fuel pump running. It was bypassed during starting with, (I think), a relay. There was some safety issue that had resulted in this arrangement.

Might be worth a look to see what checks there are in the ECU to determine whether the engine is running or not.
