absz Posted March 10, 2009 Share Posted March 10, 2009 (edited) Right had my fuel injectors cleaned and flow tested all fine and within 1% off each other, i have now fitted the injectors back onto the car and one of them remains stuck open just filling the piston chamber with fuel is there something i can do with this injector or shall a just buy a new set. ps injectors are 780cc delphi Edited March 10, 2009 by absz (see edit history) Link to comment Share on other sites More sharing options...
dandan Posted March 10, 2009 Share Posted March 10, 2009 Sounds weird.... Is it still stuck open when the electrical connector is not clipped onto it....ie...with no signal at all from the ecu? Link to comment Share on other sites More sharing options...
absz Posted March 10, 2009 Author Share Posted March 10, 2009 I have the injector out in my hand and can blow through it:blink: Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 10, 2009 Share Posted March 10, 2009 Sounds like a seal leaking/not seating to me, had this before in my old S14. Link to comment Share on other sites More sharing options...
Ryan.G Posted March 10, 2009 Share Posted March 10, 2009 Connect the injector to a good power source like straight to a battery and see if it causes the injectors to come unjammed. Sounds like the pinacle is stuck open. A quick tap might help... It does with Sard injectors Link to comment Share on other sites More sharing options...
absz Posted March 10, 2009 Author Share Posted March 10, 2009 had it clicking with a feed and threw it across the garage a few times:d still can blow past it but with bit more force. thinking of buying a new set as this will always play in my mind even if fixed.

Ryan.G Posted March 10, 2009 Share Posted March 10, 2009 I would send it back to the person who cleaned them and see is there ultrasonic cleaner helps. Link to comment Share on other sites More sharing options...
