Injectors clicking Options

[JPA914]

My '74 2.0 is running rough and I'm trying to rule out as many causes as I can. The car was running fine, but started idling low and acting like it was running on three cylinders a few minutes after being started. Now it acts this way right at startup. In trying to rule out the fuel system (I'm also looking into the ignition and injection, but that's a different thread), the following has been done:

Confirmed the fuel pressure is good at 29.5 psi
The injectors were just tested and cleaned
All new SS and rubber fuel lines (no kinks, no leaks)
Cleaned fuel tank, brand new sock.

If I stick a stethoscope on each injector while the engine's (barely) idling I can hear them all click at a regular rate. All click at the same volume without any dead spots in the sound. Can I rule out my trigger contacts because of this? I would imagine if the trigger contacts were a problem, I wouldn't hear certain injectors click at all, or perhaps there might be erratic clicking. Anybody know if that's the case?

The car sat for years and I did everything I listed to the fuel system before I attempted to start it. I've also gone through the ignition and FI components as well, but since my question was fuel system related, I wanted to keep the focus there for this thread.

When first started, it would run fine both at idle and higher RPM for a few minutes, then start to run rough throughout the rev range. Now it runs rough right from a cold start and doesn't improve after warmup.

So does anybody know if the repeated, equal volume/tempo clicks I hear from each injector are an indication that the trigger contacts are working properly and I can rule them out as a cause?

The car works as a system.

So you believe you have checked to fuel system.......so is the correct amount of fuel getting to the injectors?

Trigger points are part of the FI system and not fuel delivery. Do one at a time.
