hi,im looking for help with a 2006 tdci connect.1753 euro 3.180k. the glow plug lights flashes ,then the van cuts out. i reset it by switching the ignition off /on. this can happen quite a lot on a short run. i used a maxiscan ms300 & got dtc code p0251 ( injection pump metering control a) i have since fitted a new fuel filter(,old 1dirty, but no swarf/metal bits). i did find the pipe from the air filter to the turbo badly split. which will be replaced soon.( taped for the moment) what can the problem/s be. the van starts & ticks over fine.little bit of black smoke when revved. any ideas? thank you. steve.

 

I know the fuel pumps on these are common for packing up.

 

hi , you might know the van. it was bought from rydal road darlington, .on sunday. guy said fuel pump might be blocked. it cut out 7 times on the a1 back to hebburn. just need to get it sorted m8. cheers, steve.

 

hi, still no help or advice ? this po251 code seems to be very common on the tdci diesel ford.. have replaced fuel filter,checked for loose/chaffed wiring etc. van is still cutting out with glowplug light flashing . this happens after 1/4 mile starting from cold. & under 30 mph. someone must know exactly what the problem is. maybe imv needs replaced ? awaiting replies. cheers, steve.

 

steve i think these these have the electric accelerator pedal ,which can go duff on them .worth a shot .i think the potentiometer can get dirty on them and you may be able to clean it

 

hi, thank you for the advice re- the pedal ive had focus cars with the same, but never had problems.. will prob try & get 1 at the scrappy.could be that. anyone help with most common fault which causes po251 code. cheers guys. steve.

 

Search on here for p0251 theres hundreds of threads about it.

 

hi, thank you for the advice. i have already looked.. but will change fuel metering solenoid, the 1 with the brown plug, see if that cures it. if not its a trip to a diesel specialist with the proper equipment. cheers m8. steve.

 

hi, just a update. removed imv solenoid, tested on workbench, plunger is moving in & out when power supplied to it. so now refitted. done a leak off test. no 1 injector return is filling its bottle a lot quicker than 2,3,&4. 1 inch of fuel in no 1 . the rest under 1/4 inch ( just as a rough check) didnt measure quantity. which looks like no 1 injector is faulty. also new fuel filter fitted. , switched ignition on. glow plug light was flashing ( never did that previously) went off after 30 seconds. cant start engine at the moment as 2 of the return pipes were brittle/leaking. so will fit full new set.. prob fit new fuel pressure sensor as well. no swarf or dirt in the pipes. just hope it may be no 1 injector causing the engine cut out & the dreaded po251 code. & not the fuel injectiion pump. ! regards, steve.

 

Back in the day fitted more injectors than fuel pumps.

Pleased you've done a leak off test , should be good with a no1 injector, just need it coded in!
