I have a 2004 Ford Focus Ghia estate 1.8 diesel. Under hard accelerations the exhaust emission is a black cloud. My garage has reported a diagnostic code P2291, injection pressure low - engine cranking - pump faulty. They are suggesting I have the injectors tested and suggest this could be expensive as it takes time/is difficult to remove the injectors and testing costs £40/injector and takes 5/7days. What does "engine cranking mean?Should I give the injector test a miss and go for a new pump?Advice pleaseRegards XXXXX XXXXX

My local garage carried out a diagnostic test. Test returned trouble code P2291
Hello and Welcome to justanswer...The phrase -engine cranking..is related to the code in that it means its a pressure issue when the engine is cranking / turning..No its certainly not advisable to just go for a new pump... apart from the sheer expense, there are other things that this can be - and even if it is the pump... its always the best thing to have the pump professionally tested / repaired...and it will last as long as new one then...( within obvious reason )...Im assuming you have the TDci engine / system. The injectors on these are notorious for trouble - and at around 80,000 miles , generally need their engine management coding checked and reset .. This needs special diagnostic equipment - not just a base fault code reader machine to do.. So bear that in mind if your mileage is at all close that as above..There are as I mentioned, other things that can cause what you have - fuel pressure sensor as well - and others...The code relates to injection control pressure - so you can have a pressure solenoid fault that can cause this - nothing to do with the pump or injectors..I get the feeling you are dealing with a general type garage - Honestly ...my best advice here is to locate and take your car to a local Diesel Specialist.. They have the know - how.. and the tools - and the test equipment..to quickly get to the bottom if this for you.. and they can generally run component tests - pump etc etc in house....without all the extra costs. Use yell.com to look for a diesel specialist - or this site HERE may help you further - but do look for diesel specialists...for the reasons above...This is going to be your best - quickest and most cost effective way forward on this one for sure... I Sincerely XXXXX XXXXX have helped you - but do ask me if you need anything more..
Kind Rgds, MIKE
Feedback and any Bonuses are always appreciated too. Thank you.
Thank you for your response.
I have had the car from new and the current mileage is 34283 so perhaps the problem is not the injectors(Ref your 80000 miles)
Will I do any harm if I run the vehicle as it is?
Hello again Dave - thank you for your reply...I agree - that is low for injector troubles - thats around an average of 3.5 years in age - but .. age can cause problems as well... so there is the slight possibility...Actually though too - with such an injector problem on these - you will usually get a light on the dash...flashing or other...and you havn't mentioned that - so I suspect other as mentioned above yes...You wont do any harm no... If anything it may get too smokey to use or lose power necessitating the need to get it in and sorted as above - but you can use it meantime for sure...I hope that helps you further some..Best Rgds - MIKE..
