My 2.0 runs on 2 cylinders (1 and 3 only), Help a brother out! Options

[Gint]

Dammit! It runs great on 2 cylinders!!! Except for the occasional backfire. 1 and 3 fire, 2 and 4 do not.

I dunno. I pulled all of the injectors and fuel lines in the engine bay. They're all clear. I have 29 pounds of fuel pressure. I tested all of the injectors while cranking the engine over. All squirt fuel in a nice conical pattern and the volume appears to be the same. I have spark on all cylinders. But only 1 and 3 fire. If I pull the injector connector or the plug wire off of cylinders 2 or 4, nothing changes. They are both not doing anything. If I pull either the injector connector or the plug wire from cylinders 1 or 3, the engine dies; apparently it can't run on just one cylinder, go figure.

I'm wide open to suggestions. I need a 914 fix before the weather turns to crap.

Update!
If you read all of this thread, you'll see that bondo spotted my error. I swapped wires on the dizzy for cylinders 2 and 4 and she fired right up on all four cylinders.

I would pull the spark plugs on the non firing cylinders and see if they are wet with fuel. It would also be interesting to swap the injector plugs (1 & 2) and (3 & 4) and see if the dead cylinder follows the injector connection or stays the same.

If spark plugs are wet with fuel and/or the miss doesn't change with the injector plug, I would think ignition and check the dead cylinders w/ a timing light.

I know you're pretty knowledgeable so don't be insulted if this sounds too basic.

Edit: I see you checked spark - was that with the plugs out or by using timing light or similar means to check for spark under compression?
