Power at injectors... no power for injectors at ecu???...

[josh930]

I'm working with Dr. tweak on this....

I'm getting 12v to the wires going to the injectors with the key on, but I'm getting 0volts at the injector pin wires. I think the pins are 11, 12, and 25. When I crank I get .05v at the injector pin wires.


Everything else is fine. I just wanted to hear some of your ideas on why this may be and what should I check for having this problem.

Thanks for your help....

Are you sure you have the right wires?

Disregard the 4-5-6.. You should have 12v 1-2-3.

Yea, I have the right ones......11, 12 and 25

Could it have to do with grounds?

Yes make sure your harness grounds are good. I had 12V at my injectors but they wouldn't open due to bad grounds. I sanded them down and made sure they were tight and they worked.

I thought the injectors get 12v from the fuse box and the ECU only controls the ground side of them. So that's why you do not see 12v at the ecu pins. Correct me if i'm wrong.

No, they do get 12v.

I did find the problem. I put in new sard injectors and the prongs on the injectors werent touching the contact points in the clips. So all I really had to do was bend the prongs so they would make contact. I'm just thankful it wasnt expensive. Thanks for all your help.
