jaygee82 Posted May 24, 2011 Share Posted May 24, 2011 hi everyone, my mondeo is making a mysterious sound and i have decided it may be an injector. all the info i have read tells me to disconnect the wires off the culprit injector to try eliminate the noise. however, as far as i can see my injectors dont have wiring ? just a brass pipe coming from the upped fuel pump. im very confused, how do they know when to fire if they dont have a wire ? there must be a electrical connection somewhere but i have stared and scratched my head for hours now. please help ! p.s. 90hp TDDI - belt tensioner done and camshaft pulley investiaged - not the noise, DMF - no noise yet, pretty sure its injector.

mintalkin Posted May 25, 2011 Share Posted May 25, 2011 you will not find any wires on the injector system on a TDDI,it uses a injector pump which injects the fuel and is timed from the timing belt its the TDCI which has the wires because its a common rail system where the fuel rail is at pressure and the ecu decides when to fire the injector.

mintalkin Posted May 26, 2011 Share Posted May 26, 2011 beware of any fuel pressure that may be in the pipe, undo slowly. Quote Link to comment Share on other sites More sharing options...
