1976 eldorado 500ci fuel injected. I have changed distributor module & spark plugs, checked for fuel presure at rail (40 psi) I have spark, have 12 volts @ coil, but dont know how to check the volts @ injector car runs but only with carb cleaner. I know it is an injector issue but cant seam to know how to check them. please help I am getting fustrated with this dam car.

 

It would be better to continue previous thread, but oh well. Do you have 12v at injectors? There is a tool called a "noid light" (injector test light) it can be plugged in to injector connector. It should blink as engine turns over. Check all 8, respond to this thread.

 

I checked the inj with noid light no BLINK, I took the distributor out to get to the trigger point but don't know how to check the trigger point to know if its working, there is not much there only a square black magneto with three wires.
