im working on a friends car and his secondaries arent coming online.. they are a blue color(720's) and the car is a 88 t2 so my question is some douche before me wired in some kinda of resistor and i was wondering what application would you not run a resistor.. running a high imp. inj. on 88 t2 or low imp. inj. on 88 t2

im just wondering if the resistors are needed since i cant tell what imp. the inj. are??

 

If those are the blue Denso 720's that I have and you have an 88 you will need a resistor. Did you check to make sure the injector clip is in good shape?

 

You just get a meter out and put it on ohms. Then touch one injector pin with one lead and the other injector pin with the other lead. Low impedence is 2-3 ohms. High is somewhere like 12-13 ohms, I forget exactly what high is.

If low resistance injectors are used, then get or use 6ohm resistors. Preferably ones off a early series four car imhumbleopinion.
