Have you work on minis before

Yes I have, here is a wiring diagram for your fuel pump, it will be the white that sends voltage. there is also a fuse that gives power to the relay

Customer reply replied 10 months ago
Now Michael is the relay part of the fuse box can not be replaced I need a new fuse box

If there is no power at the White/Blue wire, check fuses 20 and 34.

The fuel pump relay is in the fuse panel at the driver's side kick panel. The lower most relay should be the fuel pump relay.

At terminal 30 there should be battery voltage all the time from fuse 20. Terminal 87 should be connected to the White/Blue fuel pump wire. Sending power out on terminal 87 should cause the pump to run.

Terminals 85 and 86 are the control side of the relay. One of them should have battery voltage from fuse 34 with key on. The other terminal should have a ground signal while cranking.

Customer reply replied 10 months ago
Michael here's a wired thing the pump has no voltage doesn't come on no prime or cranking but my spark plugs smell of fuel there soak I don't get it

ok here is the r56 wiring diagram pretty similar, give me more time to research more of the relay, and your not getting voltage but smell fuel on spark plugs? injectors must of injected what little fuel it had left but that is interesting.

Yea you know on this European cars with the fuel pump in the back seat you can feel them prime up wen keys switch on and this one nothing won't prime and yet wen I crank it my spark plugs are soak in fuel I don't get it

No none at all that's what's killing this has a high pressure fuel pump at the cylinder head How does that work look like it turns with the camshaft

here is the k96 fuel pump relay for you, verify all the circuit and let me know what is missing

Ask Your Own BMW Question

yea it does, heres a general idea of it & a procedure for removal, just be cautious.

This vehicle uses a high pressure fuel system that requires readings from the fuel pressure sensor with a scan tool.

2. Look at the data for the pressure sensor; there should be about 725 PSI at idle up to a maximum of 1750 PSI at full load.

3. Verify proper supply to the high pressure pump. The in-tank fuel pump should run at a constant 72 PSI.

it is also equipped with a 10 year warranty tsb here that part has been updated

Michael the relay was bad I replace it just now and connected the negative battery post I could hear the pump prime up strong now im hoping it starts up tomorrow i have to assemble the pump back in tank do u think with the pump not working it kill my spark as well

Thats very good news! as for your question, it depends. Was there no spark as well as no fuel? Was there spark for a short time then no spark? is there spark?

Ask Your Own BMW Question

Also helpful tip that I'm sure you already know about these, take good care of that engine, it gets costly for the VANOS to mess up, they share similarities to BMW. Engine will run strong as long as you maintain it & take great care of the fluids.

This what I'm thinking the fuel pump in the tank was not working so I'm guessing what every pressure the high pressure fuel pump had in it was soaking the plugs and possibly killing the spark im guessing
Customer reply replied 10 months ago
Yea I know I work on bmw a lot most cars I work on is Europeans but this little mini n14 engine it's a wired one for sure

That is a very good educated guess, a possibility.

Ask Your Own BMW Question

Or maybe the relay confused the spark internal short maybe?

I just try to start it and the pump doesn't prime wired could the pump be bad it's self
Customer reply replied 10 months ago
It prime it's self wen I was connecting the battery then didn't do it any more it should prime every time we cycle the key right

Possibility, maybe that's what caused the relay to go out.

Ask Your Own BMW Question
Customer reply replied 10 months ago
It I u plug the battery and plug it back in with the ignition of it will prime it self them if I turn ignition on nothing I can wait go back try nothing on the fuse box diagram you sent me it shows the wiring terminal for the fuse box I pull my off and it look badly oxides I bed this cars been flooded before the fuse box could be at fault to im change it in the morning if that's not it well I'm doing the pump

Yea very possible, there has been major floods in our country, so I'm sure those cars will be popping up. I wish I new what the pump amperage specs is suppose to be at, I'm thinking between 5-10 amps

Ask Your Own BMW Question
Customer reply replied 10 months ago
Well on both wire the white and the brown one I think I should have 12volts
Customer reply replied 10 months ago
Im thinking if I plug in the battery post and I can hear the pump energized but wen I turn the key on nothing and cycle the key nothing it's either the fuse box cutting out inside or the fuel pump has a short i have a fuse box here so I can't start there if that's not it then has to be the fuel pump what eles can it be

Yea that would be checked first. In the moment the pump wanted to work, I wonder what the amps were showing then, to see if the DME Unit shut it down due to excessive amps Or if its the DME acting up.

Ask Your Own BMW Question

Good luck! hope its either the fuse box or the pump.

Customer reply replied 10 months ago
See wired thing is the ignition is off and batter negative battery post off I install battery post back on with ignition off and the pump Will energize but wen I turn the ignition on nothing won't energize has to be that fuse box

I got the fuel pump to work if I crank it stop and then turn ignition on it energize up so pump is working but still no start is there some thing on this car that would shoot down spark doesn't fell like we're getting spark at all dose this engine come with a eccentric cam sensor like the BMW do

Before I answer that question, I think we would have to open a new question to prevent this one from being flagged, is it ok I contact customer service to see if it is ok?
