I’m needing some help to trace down why my injectors are not getting power I have power at the relay I see leaving the relay I’ve probed the wire underneath the ECM the black red, but I cannot find the black red continuing to the injectors to see where it’s broke, anybody have any insight of where the black red wire goes it leaves the area under the ECM

Or if you can share more inside of why I’m not getting power to the injectors, I’m all ears. Would like to get her back on the road

 

Forgot to add car info. 98 xk8

 

So you can see B+ on the Black/Red wire on the connector underneath the injector relay (relay fitted and ignition on (ii) )?

From there, it goes via the big multiplug that sits on top of the trans bellhousing, on to the engine loom, then via an 8-way splice to each injector.

Coupe or convertible?

 

Thanks, Michael. I thought it went through that large plug but I can’t find any wire on either side that’s black red. It comes through that plug. I’ll keep looking I guess.

 

If you have +12v at the BR wire at the relay, but you don't have +12v at the BR at each injector connector (ideally tested with a bulb connected to ground), then a really simple way to check this is to run a separate +12v wire to the harness at one of the injectors and see if the problem is solved. A Posi Tap type connector is a good way to do this.

Personally I would rather do this than try and fault find the engine harness.
