From what you say, probably. Change injectors and start it and see what code you get

Tested injectors with ohm meter 13.8 which is correct from what I can find. So what's next?
Will pull coil rail and ohm test those

Check the pigtail connections, do a compression test, get a noid light and verify the injector is getting signal, swap injectors from one cyl to another, check spark plugs. All those will be helpful in some way.

So you know the connector is shot?

well the tabs will not fold down it leaks and it took prying against the fuel rail and pulling with all I had to get it to come off

First, it takes a special tool to make those release. Hard even with those. You could replace the whole thing with ferule connectors from the plumbing section.

Those rails aren't that expensive to replace.

Recently replaced my supply line to the fuel rail due to a bad connector. Found what I needed at autozone. Wasnt fun to replace, but it doesn't leak and stays connected now.
