Oh I spoke too soon, the car was great after the new fuel pump and new fuel filter, the feel good factor lasted about 30 miles, than the engine lost power and refused to rev above around 2500RPM, even in neutral. I decided to take it for a blast on the motorway, that was a mistake, at times car struggled to reach 50mph.
So limped it back to garage, back seat out to check in tank pump, it seems to be pumping fuel across the fuel tank.
Back to square one.

Needs to be put on T4 if you was down here in Kent I’d do it for you, have you checked the fuel rail pressure sensor and plug? Does it trigger the MIL light at any point?

Nip across to see big russ, I doubt the in tank pump will cause issue, I ran for over a year with a dead one and never lost any power.

Hi, No warning lights, I will speak to the mechanic about the fuel rail pressure sensor and plug.

Thanks.

If there is more than 1/4 of a tank of fuel, the car will run fine irrespective of the ITP operation.


I would take the advice of visiting Big Russ, I struggled with a few niggles on my own car, until I was introduced to John at MGR Auto services at Blaydon.


He was kind enough to show me what was happening in real time with his T4 diagnostic machine, and better still explain what was causing the problem on my car.


I had tried other scan tools myself, but these were nothing compared to the Rover main dealer kit.


It will save lots of time/money in misdiagnosis by the garage you are using at the moment I'm sure.

Not a good test - far better to remove the cover over the passenger side rear seat, disconnect the outlet pipe, fit another bit of pipe with the other end in a jar, unplug the UBP and then with key to position II check the flow out of the pipe.

You should get a steady flow of fuel with no entrapped air. Next plug the pipe back in, disconnect the inlet to the UBP (ie the other end of the same pipe) and do the same test. You should get the same flow rate - if you don't then you have a partially blocked pipe - the end protector I was going on about earlier could be a possible cause.

If that checks out then connect that pipe, plug the UBP back in, disconnect the outlet pipe where it enters the fuel filter and place in a jar and test again. You should get a far stronger flow of fuel again with no entrapped air.

This is my 3rd Rover 75 in a row, and by far the best one I have owned, top spec, gold, sandstone leather, cruise, electric memory seats, electric sunblind auto mirrors, wipers. Serpent alloys. Wood steering wheel lovingley cared for for 6 years, no rust very clean inside, but I think it's time to say good bye.
If i had a garage I would take it off road and store it.
But I don't .

Ahhh a sad day foe me.

Well you aren't going to get much for it with it running like it is. Why not do the simple tests I suggested, post up the results and we can go from there?

Or as you have been advised, send a message to Big Russ and stop messing about with a garage who knows nothing, and have it fixed by someone who knows what they are doing


Not a sad day at all, just time to make a decision as to whether you want to keep the car I'd say


One of the best things I'd say about this forum is just about every single fault or problem has been experienced by someone or other, and even if you don't have the answer, there will be someone who does.


If you are serious about keeping your car, contact Russ HERE

I am afraid I did not fair well when I bought an under bonnet fuel pump from Rimmer’s. Well Over £100.00. It was kept in my boot for around 8 years as a spare. When I fitted it at one our Nano meets at Four Ashes, because the original one had become noisy, I thought that the clips used on the rubber pipes, top and bottom, were not tight enough because there was diesel on the bottom of the pump. Tried three or four times to stop it leaking. Steve (Artic) tried to get the clips tight, but there was still diesel on the bottom of the pump. He said it seems as though the casing was leaking at the bottom of the pump. I think it was Sewerman who stepped in with a cheap underbonnet pump, and I fitted that. No diesel on the bottom of the pump, and is still in use now. Not quite so quiet as the original, but it works. Could not send the one back as it was well out of warranty.
