First: If you replaced the lines at the fuel pump, make sure you didn't accidently swap them around. A quick check would be to remove the line coming off the fuel filter going to the fuel distributor and place it in a bucket then remove the hose going from the fuel distributor to the return of the tank (it's one of the double banjo fittings on the right side of the FD) and place that in the same bucket. You'll want two people for this, have someone jump the RPM relay and note where the fuel comes spraying out, if it's spraying out from the return line, you'll need to swap the hoses up front.

Also, anytime you replace the fuel distributor with a rebuilt or new one, you have to set the base mixture adjustment using the CO adjuster screw. It's simple to do but everyone always overlooks this part and struggles getting their car to start.

IMPORTANT: THERE IS NO STOPPER ON THE co ADJUSTER SCREW WHICH MEANS YOU CAN UNSCREW IT TOO FAR OUT OR IN AND IT CAN FALL INTO THE MIXTURE UNIT, TAKE CARE NOT TO TURNT HE SCREW TOO FAR OUT OR IN.

1. After attaching all lines to the fuel distributor, rap a large rag around the FD to absorb an fuel coming out then remove a hose from the FD that goes to a fuel injector (I usually remove the one going to injector 1 since it's easier to contain the fuel coming out of it. Don't worry, the fuel will not come spraying out of the port unless you press the air meter flap down all the way.

2. Have someone jump the RPM relay to turn on the pump. I highly suggest you have a second person doing this so if there is any fuel related issues they can pull the jumper off quickly.

3a. NOTE: WHILE DOING THIS STEP MAKE SURE YOU ARE NOT PUSHING DOWN ON THE ALLEN KEY AS YOU WILL BE PRESSING DOWN THE AIR METER FLAP THROWING OFF ALL MEASUREMENTS. If there is no fuel dribbling out after turning on the fuel pump, keep going with step 3a, if there is fuel dribbling out, skip down to 4. Use a long 3mm allen key to turn the CO adjustment clockwise (richen the fuel) slowly until it begins to dribble out, take your hand off the allen key to make sure you are not applying any pressure down on the CO screw and dab the port with a rag to wipe away fuel, if the fuel is still dribbling out, then go to the next step.

3b. Once the fuel begins to dribble out, slowly back off (counter clockwise to lean the fuel mixture) until it just about stops. Take your hand off the allen key again, dab the port with a rag to wipe fuel away and monitor it. If the fuel just stopped dribbling out, pull the jumper off the RPM relay, reattach the hose to the FD and clean up any spilled fuel. and you can skip steps 4a below.

4. If fuel is dribbling out as soon as you jump the RPM relay, back off the CO adjustment by turning it counterclockwise to lean the fuel out just until it stops. Once it stops, turn it clockwise until it begins to dribble out again and then back off counterclockwise until it just stops, again. reattach the hose and clean up any fuel spilled.

5. Reattach the RPM relay

That's it, once you make the above adjustments, you should be able to start the car and let it run to warm up to operating temps. Once it does, you can attach a DWELL meter up to the car are precisely set the CO adjustment. If you need instructions on how to set the CO with a DWELL meter, Chris Miles made an excellent video on how to do that here: https://www.youtube.com/watch?v=HKT_i82VtIo

Also, if you feel that you may have flooded the engine during the adjustments, pop the inertia switch under the dash to cut off the fuel pump, crank the engine until you start to hear it about to start, stop cranking and rest the inertia switch. That will clear out all the fuel that flooded the engine.
