Shouldn't there be 12v current on the injectors when the ignition is on and the car is not running?

(car has a Power FC if that matters)

 

Quick check to make sure that your injector plugs are functioning would be to use a noid light or spray into the air (dangerous) while turning the key to start. Please see my video here:


I believe that the injector does always have voltage and grounds to fire the injector so yes, I believe you are correct. And at the ecu, I measured 12v to the injector so I assume that would be right.

 

Yeah, I saw about noid (????) lights but they aren't sold anywhere here. I suspect I might just have a grounding problem.

 

Check your nearest auto store, they should loan them out for free (auto zone and O'Reillys have them)

 

........maybe next time I'm in the states....

 

the black/yellow wire should have 12v. i'm not exactly sure how the FD works, but i think it is main fuse -> main relay or EGI relay -> injectors -> ecu -> ground

i think the US diagram would work, as i'm sure its the same

 

Isn't the black/yellow wire the ECU ground?

There should be solid 12v so long as the injectors aren't pulsing, right?

I think the multimeter I bought might just be really crappy because its auto ranging function sucks. I would swear it shows 12 v and then starts dropping off.

 

I take it there's no fuel flowing in this video? Were your primary injectors clogged?

 

I did have 12v to the black/white wires. Car doesn't want to stay running, though. Might just need new plugs, since it would at least run a few days ago before I pulled the extension manifold and changed out the injectors, etc.
