Replaced HPFP, won't start.

Hey guys.

I've been reading through every forum and page I can find about this issue, and I can't seem to find any answers, so I figured I'd ask here.

I have a 2011 Countryman S All4, approx 103000 KM (60K Miles)

Recently, after sitting for a week in the cold weather, it refused to start. Had it towed into an indie shop that specializes in BMW. They replaced the spark plugs as they were fouled, and got the vehicle to start, but it was running rough and they said the HPFP was not giving the proper pressure and it needed to be replaced. They said the LPFP was functioning correctly. They quoted $3000 CAD, so I told them I would do it myself.

I ordered an aftermarket pump from eBay (Item # 332348290033) and went to install it today. Install was pretty straightforward, but since the vehicle was driven just the day before, I assumed the fuel lines would be pressurized, so I decided I would pull the fuse for the fuel pump and start the car so the lines should depressurize. Before I did this, I started the vehicle again for a few seconds just to verify it still starts fine. So I removed the fuse, tried to start the car, turned for a while and that was that.

I followed the instructions from several DIY's, replaced the pump, and reassembled everything.

I went to try to start the vehicle, and nothing. Just turns and turns and turns and won't start. Yes I reinstalled the fuel pump fuse that I had previously removed.

After searching around for any other causes, I figured my new pump might be a lemon, so I reinstalled the original HPFP to see if the vehicle would at least start and run like it was before. Nothing, just cranks and cranks but won't start.

So I reinstalled the new HPFP again just to be certain, and nothing.

Do you guys have any suggestions for what I could try next? Is it possible that the LPFP was also a problem but my Indy shop couldn't diagnose it before replacing the HPFP? Is there a simple way to verify that the LPFP is working correctly?

Thanks a lot for any help you can offer.

Alex

I forgot to mention, before attempting the HPFP replacement, I was getting a CEL and the code was P0172. Since replacing, I am still getting that code, but additionally am now getting Mini code P15DF. Hopefully that might help pinpoint the problem.

The main part is included with other parts (not just the HPFP itself). KT or Kits are noted. The main part is the just the part number. One from MINI and one from a MINI supplier, and one from Peugeot (PSA) direct (MINI shared engine).

See link below:

N14 engines

https://www.ecstuning.com/Mini-2007-Cooper-R56-S-Coupe-L4_1.6L_N14B16A/Engine/Fuel/

Over the last year or so the price has gone up from MINI and the suppliers. My bet is when it was first posted it was at a warranty replacement price as the comparable BMW engine HPFPs were way more than the PSA/MINI one, at that time.

FYI. The price of hpfp's have dropped recently. You can pick them up from a dealership for around $500. The one for a 2011 s is now $506 as opposed to over $850 from some online vendors.

First of all thanks so much Sandwlkr for the write up. Super rad of you to take the time to help out.

Just finished up 1st HPFP install and it was pretty uneventful. Took a little time with some stuck plugs and also I had a 3/8 inch torx set that made it a little more cumbersome.

For the weekend youtube mechanic.... make sure you swing by harbor freight to get the crows feet wrenches in metric and 1/4 inch torx set will make your life alot easier. Because of the tight space there's an increase chance to cross thread when putting it all back together.
Magnet to catch the bolts is a must also.

Sandwlkr mentioned this in his post as well.

Oh yeah and don't forget to plug the cam sensor back in until you hear a click LOL!

Can anyone clarify the differences between the N14 and the early N18 fuel pumps?

There are multiple differences between the 2 versions and they are not interchangeable.

Replaced pump after it tested bad still not getting pressure

I took it to a shop they tested the fuel pump said the hpfp was bad. I replaced it and the car still is doing the same thing as before. Starts and shirts right off again. They are able to run the car off starter fluid. The intank fuel pump is supplying 10 bars but the hpfp is only putting out 10bars. Also the wires running to the hpfp do they just monitor pressure? Wondering if maybe they are apart of the kssis.

Did you check to see if the pump is covered under MINI extended program? I'm thinking the S model was but maybe not what you have.

All sorts of good info here https://www.newtis.info/tisv2/a/en/r...ch?q=fuel+pump for the pump, etc.
