my rs turbo efi is fireing on two cylinders its the two at the crank pully end, i have power going to the other two injectors closes the flywheel end and i have a spark on the two plugs on the cylinders that are not fireing other than the injectors not working can this be a fuel pressure issue or something ells??

Providing it's a good spark, and plugs etc are not cracked check injectors 3 and 4 earth's are switched as the injectors run constant live not earth.

Thats fine then, have you checked the condition of the injectors I.E, there not blocked?

not yet that is the next step, can i blow them out with an airline??

NO, but a better way would be to swap the 2 known working ones with the 2 suspect ones and see if the running cylinders move with that.

ok iv had the two injectors cleaned and activated them manualy and blow air threw them so as far as i can see its not the injectors.

Do you know if there is fuel coming from the rail to these two injectors?, I wonder if the phasing is out to the injectors otherwise.

phasing?? well when i pulled the two injectors out of the rail they smelt of fuel and it was dripping from the rail.
