02 Chrysler not getting fuel

Try to get a 02 town and country running again after putting a universal oxygen sensor in. The van ran good before.

I was on my test drive and was looking at O2 sensor activity and would go down to 0 volts. The van started lacking power, running rough and then quit. The odometer was reading "done"

It will just chug every now and then when I try to start.

I bought a direct fit 02 sensor and there is no change.

It will only start if I dump gas in the intake. I think the PCM is not driving the injectors, what would cause that?

I would like to get to the bottom of this.
