Stumped on primary injector trouble

i'm having issues with there being no fuel when i crank my engine so i went through and tested somethings.

ohms test

injectors each test with .000 resitance as where manual says 13.8ohm should be found.

Injector plug on harness had 1.386ohm on both.

volatge test

injectors had none but thats no surprise

the plugs on the harness had ~8v when cranking and like 0-1v whenver else.


I had a extra battery so i decide to run current through the injector so see if they would click and they did.

I'm just stump with why my primaries are not firing and was wondering if anyone had an idea.

Thanks

Could be bad wires. Check your grounds too.

that your problem

the odd 1.36 somethign ohms was just from the wires

pull them. Hook them up to a 9v battery and see if they click.

didnt' see that

https://www.rx7club.com/showthread.p...hreadid=274942

Should be 12v from the relay. Maybe they not opening all the way.

the resistance still makes me think it's bad injectors even if they do click.

try jumping 12v on the injector and have the fuel line pressureized. See if it flows then.

I think that when a solution is not mentioned by the owner, we can assume that they did something really stupid and that is why it isn't posted.
We should assume this to force them to post!
