gents

 

i tried my new boost controller at 15psi today

 

running stock injectors, turbo technics stage 1 turbos and john dixon chip ( same as jwt i believe )

 

everything was fine till i came to start the car again and a missfire in the no6 cyl was traced to a dead injector :mad:

 

checked the spark was ok cleaned the injector connections still the same

 

did the listening trick with the screw driver no clicking on no6 :smash:

 

is there a way to test them in situ? what are the volts to the connector can i test that in some way?

 

am i able to remove the injector without pulling the plennum??

 

did the 15psi cause this??

 

any help greatly appreceated i have some spare injectors that i can replace them with

 

cheers

Check the resistance between the terminals with a multimeter you looking for between 10 and 14 Ohms.

Injectors can be checked electrical with a test meter set on ohms, this will give you the resistive value, compare it to a working one, if it has no resistance and has gone "open circuit " then it is truely dead then.

 

As the ecu has had some work recently make sure the big blue connector is in square as if not a bad or no connection on one of the pins for the injectors is common.

 

1) Check ecu connector

2) So test electrical resistance

3) 15psi will not of killed it.

3) Plenum off if replacement required ..doh!

Either that or the 'dremell method'.Only for the brave though...

Worked for me on no 5 cylinder.I believe you can do any injector.

well it was the drill method for me just finished now changed the injector, broke the old one coming out though bit rough :mac1:

 

the old injector i had im not sure about condition age ect?? :smash:

 

anyway fired her up and it has cured my missfire but i have a slight miss could it be the old injector coming back to life will try the datascan now see whats happening

uh oh still a slight miss fire again i can here the injector working now with my ear on the screwdriver maybe the old injector is just blocked, will run the zed tomorrow a bit then see how i get on
