Rover 75 fuel pump 130 bhp
 

Hi iam new to this group after taking charge of Father in laws 2005 cdti
He is now in care home with dementia but kept on reminsing on his beloved rover so I had it moted failed. Welding on 3 jack points on cills and broken coil springs.
Iam handy with welder as I restore old Sunbeam Alpines.. So all work done
I have been using care for 4 months now and l just love. Love love it.
Now to my query
It let me down a few times. Think it's intermittent fuel pump gremlins... Single pump system.
So now I've removed pump from tank then motor from pump( very good instructions on this forum.. Only extra tip would be soak motor carrier in red hot water it Seperates easily then)
Now to point it seems like all motors are for 115hp engine? Are these same motors as 130 hp engine? If not where can I get correct motor..? Iam a tight NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- so cheap as chips
Cheers

Same pump and same engine, its only the map that's different. Would be worth considering getting the '160' map although other maps are available!

I am not convinced a CDTI needs a remap unless it is towing a heavy weight such as a caravan, I am of course assuming my CDTI has not been remapped.

Cheers I'll order one thanks for quick response

Very unusual for the single pump to fail, what are the symptoms?

It's certainly a capable engine without a remap but mine was a 116 so the map made a significant difference and for me it wasn't a question of if it needed it but more that it makes it a much more pleasant car to drive with it :)

The CDT is a dog, I have one. Without doubt the CDT does need a remap but my CDTI and the one I test drove when I got my CDT are noticeably livelier. I would say anyone with a CDTI, should drive around with it for some time, before deciding to remap to 160, however, if they are going to tow a 4/5 birth caravan get it remapped. 2 birth or 3, try is standard and then decide.

It's starts fine them after short journey no joy in starting
Unplugged inlet at filter.. No fuel... Power to motor but not whirring
Connected to electrics outside tank nothing..
Turned ignition key few times motor eventually started
So suspect intermittent fault

Nip over the water and see the mg rover breakers on English St they will have one in stock, must be from the single pump system as the in tank pump from the twin pump system won’t be any good for you.

It won't be the pump, when it doesn't start or cuts out have a look at the oil pressure warning lamp on the dash, and if it is lit ;)

Take a look in the plenum chamber to make sure the ECM isn't wet, characterised by a tide mark on the pollen filter.

I can count the number of single pump variants of 75 where I have had to replace the pump on a single finger, and that was after the chap I bought the car from had fitted a pump from a twin pump car :duh:

I had a "Dog" which was remapped to 130,(160 not available at the time) It made a difference from the std 115 but always thought it could be "Better".

Along came the 160 re-map which I had done and the difference is chalk and cheese. Fully recommend the upgrade weather you are towing or not. It is now the car performance wise it should have been from Day 1

Don't know where that is

OP now has 2 opinions on remapping a CDTI, one recommends and one is not convinced but that is providing mine is standard.
There is also driving style to consider and this must play a major part, I am not aware of a difference between when I drive my remapped cdt and my cdti. I have never wished solo, loaded or with just a 6x4 trailer that my cdti tourer had a remap. Only time is when towing the caravan and so my driving style it would seem, does not make use of the extra power a remap gives under normal driving.

Will check thanks. Tried to put pump back in today but ir all cam out with a load of plastic and pipes . Cannot figure how ot all fits hayhum

I will check this but in the meantime I have to reinstall pump in tank but loads of plastic and pipes are in the way and I cannot figure where they go.. Any ideas pictures would be of great help

Update on pump
New pump fitted and working for 3 days
Result. No
Will not start today
No power to pump
I checked plenum as surgested
Small amount of water unblocked pipe
It must be ecu water fault????!!
What to do now
Any advise cheers

Get in touch with Big Russ, he can sort the problem for you.

Yeah, well I did think the pump would be ok, so to ask the question again, when there is no power to the pump is the oil pressure warning lamp lit with the key turned to position 2?

It's a fairly standard test for late cars fitted with an EOBD compliant ECM, as if the oil pressure lamp doesn't light, then the CANBUS controller in the ECM has bought the farm ;)

Not the end of the world though as it can be sorted out at a reasonable price as mentioned by Trikey :cool:
