Question one, the four bolts holding the IP drive gear cover down is the wrong way to remove the IP.
When you swap the IP, the drive gear is now not in the same location as it was when it was removed, so the IP is out of time with the rest of the engine.
Correct way is remove the three nuts holding the IP to the drive gear cover and the three 5/16" bolts that hold the drive gear to the IP shaft leaving the IP drive gear meshed with the cam drive gear so everything stays in time.
When you turn the key on with a cold engine, you should have power at all three electrical connectors on the IP.
The front connector on the drivers side is for the fuel shut off solenoid.
It should have power when the key is on at all times.
The timing advance solenoid (rear drivers side) and the fast idle solenoid (passenger side) will not have power when the engine temp goes over 112 degrees.
Have you already swapped the IP, the wrong way?
If so don't feel bad, I know a couple of the manuals tell you to do it that way.

Yes, You should have left the IP gear cover on, Removing the IP with that cover affects fuel timing.
It's extremely hard to re-time it now because all the marks are inside the front cover.
Dave Sponaugle is the one to respond to this, he will shortly.

How could you ever not move that gear though? One tooth out and your timing is off. Getting them lined up again is tricky.
Not sure why you would have fuel before and not now, unless the fuel shutoff solenoid isn't getting it's signal to be on? Even if the timing is off you should be getting fuel, just not at the right time.

May be its good thing you're not getting fuel. If you timing is off, bad things can happen! It won't take long either.
No matter where the timing is, you should be getting fuel. I'd double check my timing before I went any further.
