Good chance you crossed those 2 fuel lines at the fuel filter.

Does the pump run?
If you accidentally swap the fuel supply and return lines, it won't run. BTDT.

The lines are right, I pulled them both off and turned it over to make sure and still no fuel. Tank is full. No I can't hear the pump kick on. I'm lost haha

plug in the green diagnostic connectors.

 

this will make the fuel pump cycle on and off.  Or it should.

 

If you can hear the relay clicking, but the pump doesn't run.....start checking fuses, and maybe jumper a wire to teh fuel pump under the seat.

 

Oh and check the intake manifold grounds again.  All ECU function ground through the bolt on the intake.

I connected the test plugs last night and it was clicking, but the pump wasn't coming on.
I checked fuses all looked good.
I'll check the grounds when I get home.
Thanks I appreciate it.

There is a large black wire with a red stripe that I didn't know where it goes so I just hooked it to the bell housing thinking it was a ground but I'm not 100% on it

So don't give up.
 
There is a relay that controls the fuel pump under the driver side dash. you should hear or feel it click under ignition.
The hot wire runs to the pump and then it's chassis grounded.
 
Consider running a hot wire from say a tail light <no sparking allowed here> and see if it will spin.
Prove to yourself that the pump is functional by itself. 
 
2 people / While starting key ignition, Maybe tap it with a hammer to get it to spin. <if this works your pump is in the sunset of it's life anyway> replace it.
 
The pump needs fuel to cool itself so be careful if you remove it from the car and run it on 12v, but it's worth a test.
The thing is a jet turbine engine and is VERY sensitive to debris, dust, goop.
 
There is a fuse under the dash that drives it too.
Since you took the engine out - are you sure for SURE that all your grounds are well 'grounded'?  no rusty connections
12 volt at your battery?  
 
Someone mentioned fuel in the tank already... 
Make sure there are no pinched rubber hoses anywhere

I'm home now tracing wires out. The black and red wire I was talking about goes to the negative batter terminal.
Where is it suppose to go after that?
Thanks!

Oh, you mean a really big wire.  That is the Negative cable to the engine.  It does indeed go to a tab, that is bolted thorugh the upper starter bolt.

check to see if fuel comes out at the filter when you crank the engine.

You will need to change out the o-rings in the system to the green ones compatible with 134. They are available most auto parts stores as a kit with the adapters for the service valves too.

How did the firing order being off solve the fuel issue?

 

Did you not have the distributor plugged in?  That would stop fuel from flowing during cranking, but still should have had an initial priming at key on.  What did you fix?

Agreed: How did we get from no fuel pressure to spark plug wires to R134A?  your problem statement totally changed.

I don't know honestly.. I wasn't getting fuel even when I had both hoses disconnected from the throttle body and ran into a cup to make sure. I changed spark plug wires the the correct firing order and that also fixed my fuel issue. I don't understand how but it did.

I converted my a/c system from r12 to r134a and now the compressor comes on and kicks back off after about 30 seconds does anyone know why it would be doing that?

Do you have a gauge set? Need to know the pressures are in the normal ranges. There are pressure switches that shut it off if out whack.
