P2291 Injector Control Pessure Too Low - Engine Cranking


Was the fuel filter a proper Ford/Bosch one?

Get a leakoff test done on the injectors, Who reconditioned them? Did they supply new calibration codes?

Knocking noise from where? Engine itself or drivers side or passenger side?

Drivers side, Crank pulley or belt tensioner common,

Passenger side clutch /DMF common.

Engine itself, Misfuelling, Injectors or pressure issues?

Leakoff test is not conclusive but a decent and cheap guide before more expensive measures are needed.

Hi. Thanks for answering back. The fuel filter is a Mehr the same I-m using for the last 2 years. Tensioner done about 2 months ago, new DMF, clutch kit, bearing and starter about 1 month a go. The injectors have been done by some place specialised on recons and new codes for them . Crank pulley ok just the alternator bearing a bit noisey. It sounds like an injector knock and once the engine warms up the knock is gone

New codes as in the old ones printed on them when they were new? Or were they reconditioned then put on a
machine to supply a new calibration code?

I say this as there are so many cheap injector reconditioners out there, Couple on ebay make many claims yet
may work from a flat above a shop?

You could recondition them yourself or let me do them, here is my setup :D

PS.. Yes its a joke but i bet there are real people out there doing them with a similar setup.

I think a leakoff test is your next step or a proper injector diagnostic at a registered delphi dealer.

Thanks again for reply Purple. Yes thei were provided with new codes. A mecanic from Ford told me that this is to do with the pump and that will cot me 3500 € (about 3200 sterling) to fixi it. So easy for them to put u off from having anything to do with a ford car again :(((((

Aldo .change that filter ..its on my hit list of probabl cause ... i had an experince of one . not great atall.. the pipes the fuel line clips go on may not be the proper dia.. hence air . the filter .may have a ballbearing non return valve on the lift side which is not on the genuine filter .. so if you stil have the old filter and it was working ok before the service stik it back on and see what happens . if not get a . motor craft filter . Also . do a leak off test as above ..and if you find the injectors are iffy then have them done . dsl . services .ballygoggan rd. are a good starting place . ballyboggan rd is in sth finglas . not a million miles mls from u and may be worth noting .. also you may have a pump problem as the mech .has said . if so then thats anothe story ..pumps are expensive to do . but that quote is silly ... also did you check the glowplugs .. most mondo diesels are stogy on cold mornings and these mornings have been cold but are especially so when some of the glowplugs are not working . if you can do a resistance test on the glowplugs or if you cant do this take them out carefully with wd foty and a warm engine .. they shuld come out easily enough and test them out by flashing them across a 12v battery ..youll know immediately if they are worling of not as they will glow red . dont burn ur fingers . replace then with neru or bosch..about 12 yo yos each ..consort . or halfords.. s
