What's it take to replace injectors and cold start valve?

Rumir has it it's available in a few local groceries although it's tradiutionally a southern thing, right?

Seems to be, but I found it in a small northern CA supermarket chain called Nugget. But they specialize in gourmet and hard to find things.

Connect the grey plug that's on the regulator to the blue plug on the cold start injector. That supplies a constant 12V to the injector once the key is on. Crank the engine. If the injector sprays (aim it into a jar!) it works. If it doesn't, it's bad.

Don't leave the grey plug there, it will flood the engine terribly if you try and run it this way.

If it's bad, you recommend a new CSV?
Mine's getting power, but doesn't spray. When I swap plugs I can "feel" it trying, but nothing is coming out.

Disconnect the injector from the fuel line and see if it "pisses".
If it does, it's the injector (clogged or stuck closed), if it doesn't it's the fuel distributor not performing as it should.

The latter can be caused for different reasons:
- No supply to the FD (check the feed line, CPR line to the FD)
- Stuck or clogged valve inside FD
- Bad PPR (primary pressure regulator)

Thanks for your help, Welmoed! Noted for sure. Thank goodness the problem wasn't a stuck/clogged valve inside the FD (or issue with the PPR for that matter).

I'm not saying this DID happen, but it's possible that last night I found the inertia switch was inadvertently triggered.
