First of all I want to thank everybody for helping so much with my repairs. Now that's out of the way.



I need to get back to basics with this secondary injector problem. I need to verify that my injectors are coming online before I go changing settings and maps and all that.



How do I test them safely??? This is the first step I need to take. I've changed most of my upgrades back to the level my car was at before I blew my motor last year. That includes stock injectors, rails, and regulator. I left the fuel pump upgrade alone and didn't re-install the unit that was removed from the back side of the lower intake when I did the secondary rail upgrade. Anyway, what do I need to do?



I want to do again!!!

 

I am not sure how much voltage the get but I assume seeing any voltage would confirm that they are getting a signal. You need to get a DVOM (digital volt and ohms meter) and test the wires through the injector clips. If you can get your hands on the electronic schematic WSM it should point out how much voltage you should see and which wires are hot and which are grounds.



Have fun.
