I've got a '74 2.0 with the original fuel injection. It hasn't been started in 5 years until this week. I drained the fuel and put in a gallon of new gas. Here's the details...
New wires
New plugs
All the cylinders have compression
Each plug has spark

2 and 4 are not firing

Maybe those injectors are clogged? Trigger points? Opinions?

First, look at the grounds under the right side of the intake plenum. Then the trigger points. Get yourself a "noid light" for that purpose.

The Cap'n

Does a noid light allow me to test for signal from the wire that plugs into the injectors?

If my problem was with the trigger points would it be 2 & 4 paired together?

Yes and yes.

Uhm, new wires, maybe check to see that you didn't put the new wires in cap wrong.
Should be 1,4,3,2., clockwise rotation. With #1 pointing toward the driver, 4 pointing at passenger, 3 pointing at right rear wheel, and 2 at left rear wheel.
Don't ask how I know this!

My first thought was that I had plugged the wires into the cap wrong, but I have quadruple checked the wires. I' ll look at the grounds and trigger points today.

Alright! Now I'm getting somewhere. The noid tester indicates the injectors are getting a signal. After confirming that works, I took one of the bad injectors out and found the pintle is stuck so I'll try witchhunter's services for the first time.
