Called out the RAC and after 2 hours he had no idea what the problem is,plugged his computer in and everything is working fine even though it just wont start.
Had to have it towed home 300 miles and stuck in cornwall minus a car.
Any help would be most appreaciated.

Did U fin out what the problem was, I have a 75 that also refuses to start!!!!

Hi,

Have just bought a 2000 CDT Rover 75 that had some panel damage ( funnily enough my brother in law who is a panel beater found it..Hmmm ) Anyway, as soon as we got the car it was intermittently hard to start. At first we thought it was low in fuel & parked at an angle. After topping it up with a couple of litres & pushing to a flat surface it still wouldn’t start. We then removed a fuel line from the diesel filter and it started. I thought replacing the fuel filter would be a good idea & did so. At this stage I noticed that the drain holes were blocked, but had no idea of the consequences @##@!!!@@(&^$K!!!!!!!!!!!!! Anyway we moved into the shop and commenced repairs. Of course we used mig welders & spot panel dent removers. When we moved it off the bench, no start.

After enough cranks to drive a considerable distance and flatten several batteries, we decided to tow it a repair shop that specialized in diagnostic & electronic issues. His response after several hundred Euro was that the ECU was caput because he couldn’t access it. At this stage we thought the new spot dent remover must have arced the ECU. At this stage I also started looking on the Web and discovered problems with ECU swimmers……. Anyway we then sent this of to be repaired and it came back testing OK.

After refitting and more continued cranking I returned to the web, this time I noticed some discussions of starting issues with insufficiently charged batteries; ie the lights coming on when first cranking. Excellent thought, problem solved. So this morning I headed off with a fully charged battery and some anticipation of resolution……Hmm no different.

After analysing it seems to that there are intermittent unexplained happenings.

- Some times the under bonnet fuel pump is powered, other times not.
- The pump in the tank appears to go non stop ( I thought this was only for 3-4 seconds when the key was first turned on)
- Some times the engine management light appears, sometimes not.
- When it does appear, there is an exclamation mark in the middle.

At this stage we think we have a power supply issue, but until I get hold of some manuals or some kind soul to donate time and energy into my project it is parked unhappily draining in the rain.

Any suggestions and tips short of using a larger hammer or an unexplained fire would be more than welcome, in the meantime my family are hiding the matches.

Regards Geoff

If its been in a bump, have you tried the fuel cut off switch??

Just being lazy and not looking in Haynes, but where is the fuel cut off switch?

Cheers

Geoff where is the car?
It really needs to go on Testbook for starters

From your description the engine ecu or related electrics do sound suspect

The two diesel pumps one in the tank and one next to the battery are wired in parallel both are powered by the same relay in the passenger compartment fuse box they should come on together every time you turn on the ignition for a minute then will go off until you start the engine where they then run constantly if not then the engine ECU may be faulty
