P0251 - Injection Pump Fuel Metering Control A Malfunction (Cam/rotor/injection)
Posted 29 February 2012 - 09:21 PM
Driving along, put foot down a bit to join motorway revs going up (2nd/3rd gear i think) bang on 3000rpm got a cluck and the turbo cut and the glow plug light started flashing, turned off and on again and went over 3000rpm and it hasnt happened again.
slight wobble on idle.
notice it smelt funny when i got out for a few seconds not sure of what oil/diesel/buring clutch?
this car is a previous cat C write off, hit in rear on passenger side.
just had idle tensioner, belt and crank pulley replaced yesterday at the costs of £370

The fact that you have a bad idle is a sign of injectors (changing the fuel filter if history is unknown is a good thing to do though, but lease use a bosch or ford one as ones from motor factors have been known to cause issues)
If you change the filter and problem persists, then do a leak off test on the injectors , be warned though it can be costly to fix if it isnt the filter

Gona have a go at changing the fuel filter (it looks really old and my mechanice thinks it could have water in it) also changing air filter aswell ford good measure. we are gona cehck the boost pipes do as i think there is a split somewhere.
Also i noticed that the fuel lines to the filter look brand new?
Also there is no smoke which really confuses me as if its an injector issue is there not usually lots of smoke?

What software are you using to log ? also are you connecting with an obd cable or bluetooth? If it is bluetooth that could explain erratic readings
Throttle being at 100% even when its not could be a faulty throttle switch, I have heard of this once before appearing with the P0251, but with that there was a problem with the injectors and the throttle switch was secondary. The accelerator switches aren't to expensive to replace

If there's no smoke does this mean to lean or to rich.???
No definitive result from leak off test only other option is to remove them for bench testing.

Noted you asked about formidable on another thread, the software is free but the leas is about £20 ish from ebay. The lead is different than normal obd leads, and it will also allow you to recode injectors which some people have allegedly done to help with injector problems (sometimes the ecu loses the injectors codes)

i am coming round to the fact that i may have to get new injectors, if this is the case id rather do it all myself and save !Removed! loads of money but ill do loads of research first i think

Formidable will work with a normal lead for reading codes and I think live data, however a normal lead will not allow you to reprogram the injectors. You can try beforehand anyway by just downloading the software.
