Hi everyone. i have an issue with fuel shutting off after injector cleaning and a seafoam treatment. was doing just fine then fuel cut off for some odd reason. feed pump in tank runs when direct wired but nothing when key is on and starter is pushed.is there a reset switch somewhere or a workaround to tell the darn thing to gimme some gas? any help would be appreciated. been working on this thing for a month..bought it for wifes xmas present..2011 clubman s. replaced coils/injectors/cam sensors/knock sensor/crank sensor/all vacuum lines/plugs. seafoamed through intake..massive carbon showing when i hit it with endoscope. misfire on 3 this whole time but after first treatment it started firing with huge knock in 3. then poof..fuel shutoff.compression test on all 4 cylinders topping at 210psi. removed valve cover. chain tensor perfect..chain nice and tight. very clean. new turbo. im running out of options and have gone through threads everywhere for fixes. recleaned injectors after fuel shutoff and soaked plugs..only tips.. and removed carbon. saw on a thread that maybe a reset under/near/on airbag unit so stripped interior and found NADA! fuses good. before all this i hit fuel pump with pressure gauge and had 72.5 so it was within spec. going to detail interior hard since the seats are sitting on floor in garage right now after stripping carpet to see if the reset was where thread says..lol. im running out of thoughts on this. THANK GOD im an older guy with a ton of patience. any help would be AWESOME and ty in advance for any thoughts/suggestions or even any your an idiot Dave comments. MERRY CHRISTMAS EVERYONE!!!

 

does the engine spin/rotate either when pushed to start or by hand?

did you try quick start spray to at least see if the car runs and it was indeed a fuel issue?

did you connect the fuel pressure sensor on the rail?

where are you located?

 

yes it cranks. tried starting fluid..all connectors connected. getting nada. no fuel pump action when key turned on.car just said im not gonna run..sigh. i was almost there..:( im in houston texas

 

Do you get OBD reading? did you check the plugs into the ECU? prior to this, did the car run fine?

 

no codes. had cleared them..have a scanner. prior to this it ran on 3 cylinders..no fire to #3. plugs into ecu checked. all ignition wiring traced and checked. all injector wiring traced and checked. when seafoamed #3 tried firing with a big knock then fuel cut off.after initial treatment the car started running much better then after a short drive #3 started firing but as i said a huge knock started..preignition..and fuel said adios.im starting to lean to the hpfp issues known with vehicle and taking it to mini in morning for a warranty check on it. they are gonna bend me over guaranteed but i need to get this going. starting fluid through map port on intake fired the cylinders just fine with some knock in 3..never caught on from fuel starvation..sigh.only codes from before were p303..just that.i also replaced fuel relay.

 

so, to back track a little, we know in order for the engine to operate, we need 4 things: 1- air/compression 2- spark 3- fuel and 4- timing.

you checked 1 and 2. 3 is also checked and under investigation for now. can you check 4. is the timing set correctly?

how did you know that 3 was knocking? did you check the knock sensor? did you check the crankshaft sensor?

 

Also, verify that the cylinders are actually dry. not flooded with fuel or cleaner.

 

got fuel going..was a short. but still a miss in 3 all others running better than ever. still half power though..:(.

 

where was the short?

 

wiring coming from tank . good fuel now..still miss on 3.

 

i guess you need to go back and check spark, compression, and fuel on that cyl. Could also be a dead circuit in the ecu!

 

thanks man. im praying its not the ecu but starting to look that way..sigh.

 

well it happened to be the dme and now it runs perfect. ty for replies and help minitobe. have fun everyone.
