i bought these injectors 65# per hour low impedence injectors for my 87 t2 now with them plugged in and the key on they make a horrible buzzing noise,,what the hell is the deal,,is there anything i can do besides putting the old rusty shito injectors back?

 

TTT

 

If the injectors are used, sounds like they need to be cleaned. Remember that high/low cutoff for injectors was 87.5, so you may have the wrong injectors for your car. Check the Mazdatrix site under the fuel section for the exact VIN numbers where the injectors changed.

 

well i deceded to test this out,,so i take out my new expensive injectors,,and just plug in my old ones and they buzz too,,,then i get out my DVOM and test the wiring,,,i have 12v on one side and .25-.5v on the other,,so the injectors are getting power on both sides

which brings up a question,,i saw a thread about grounding you injectors,,could i just do that and not worry about it. by the way the secondaries are the only ones doing this

 

Your secondaries should not be receiving power until the engine is under load and spinning faster than 3500 RPM. Sounds like a wiring problem.

 

that is very strange
