Re: no fuel at fuel rail
Assuming it is fuel injected, is the fuel pump operating? Check to see if you can hear the pump when you turn the key on, usually located in or on the fuel tank, pump should run for 5 seconds or so when you turn the key on and then switch off. If you can't hear it, find the plug for the fuel pump wiring at the pump, unplug it and use a test light across the terminals to see if it is getting any power (remember that the power will only be there for 5 seconds or so after you turn the key on). If it is getting power, then the pump is dead, and if it's not then there is an electrical problem. Also, some euro cars have a fuel pump shut off switch which activates in the event of an accident, isolating the power to the fuel pump. Check to see if your vehicle has one and reset it if necessary. If pump is running, check fuel lines to see if damaged or crushed.

aaa the north star motor is notorious for small leaks in the fuel rail lines ,seeing it's older look over the fuel rail ELDO used a few little rubber hoses in and line and at bends in the fuel line an gas can deposit under intake manifold ? rough idle could be a vacuum leak,again go over your hoses and replace any in question.
Is there a pump in the tank ?. I am not familiar with this car, but I had a similar problem with my Citroen Diesel, /Peugeot simila. and the low pressure pump in the Fuel tank had failed. In the car stated the tank is under the rear seat, and entry can be gained to the tank/pump from here
to clarify, if i understand correctly your old engine has one fuel line and the replacement has a feed and return line on the fuel rail. if this is the case the usual thing to do would be to use the fuel rail and injectors from the old engine"stock engine pulled from your vehicle" Its not unusal in an engine swap to need to re-use the origianal sensors, harness and fuel system due to design changes from year to year. in your case, the engine going in is a year older than the one being pulled so i would definately use all componets off of the 95 placed on the 94 replacement engine make sure to use the factory harness for the 95 as well. please forgive spelling and grammer long day at the office Good luck let me know if you need any further help!
FIRST NEED TO RELIEF FUEL PRESSURE REMOVE GAS CAP RELIEF GAS PRESSURE IN FUEL TANK.THEN REMOVE FUEL PUMP RELAY THEN START ENGINE UNTIL IT DIES LACK OF FUEL,CRANK ENGINE OVER FEW MORE TIMES MAKE SURE FUEL OUT OF FUEL LINES. THEN YOU NEED TO REMOVE AIR CLEANER CROSS OVER TUBE ABOVE FUEL RAILS. DISCONNECT LINES AT THE ENDS OF THE FUELS RAILS ASSEMBLY. MARK AND DISCONNECT THE FUEL INJECTOR WIRE HARNESS CONNECTORS. REMOVE THE FUEL RAIL RETAINING BOLTS, DISCONNECT THE VACUUM LINE FROM THE FUEL PRESSURE REGULATOR. REMOVE THE FUEL RAIL ASSEMBLY FROM THE ENGINE. IF YOU HAVE AUTOMATIC TRANSMISSION REMOVE THE THROTTLE PRESSURE CABLE AND BRACKET TO REMOVE THE FUEL RAIL ASSEMBLY.TO REMOVE FUEL INJECTORS JUST REMOVE CLIPS THAT RETAIN FUEL INJECTORS IN FUEL RAIL. BESURE GO TO DEALERSHIP BUY NEW FUEL INJECTORS O - RINGS.APPLY A SMALL AMOUNT OF ENGINE OIL TO THE O - RINGS TO AID IN INSTALLATION. TORQUE FUEL RAIL BOLTS TO 100 INCH LBS.
you don`t say what motor is in this so here is a basic procedure, find the fuel rail where the fuel lines connect to at the intake manifold.disconnect the fuel lines(be carefull you could get gas in your eyes from fuel spray or start a fire due to hot engine)these lines have high pressure fuel in them.look at the fuel rails to see what all is in the way to remove them and remove interferance items.remove the bolts that hold the rails to the intake manifold,gently lift wiggle the fuel rails and you may have to pry up on the rails in places to get them to come out with the injectors attached the rails.you should make sure any debris is removed from around the injectors so no dirt falls into the injector holes before you remove.then you can remove the injector to rail lock clips and remove the injectors from the rails.clean areas were the injectors will be going apply either gas or silicone on the injector O rings then install injectors to rail install lock clips and reassemble.replace all the O rings as they get dried out brittle and crack or split.re-install removed components start car and check for fuel leaks.

Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
Properly relieve the fuel system pressure and disconnect the negative battery cable.
Remove the air intake duct, as necessary for access.
Tag and disengage the fuel injector electrical connectors.
Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
Loosen and remove the fuel rail retaining bolts.
If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
Carefully lift the fuel rail assembly and fuel injectors from the intake.
Carefully release and separate the fuel injectors from the rail assembly.
Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
Install the injectors to the fuel rail assembly.
Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
If removed, connect the fuel lines to the rail assembly and secure the fittings.
Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
Engage the injector electrical connectors.
Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
Along the reaer or the motor on the top is the fuel rail. It has the four injectors with their respective wiring harnesses. They all look identical. On the driver's side of the fuel rail is a metal cylinder standing vertically and suspended by the fuel rail mounting bracket. the fuel connection come out of the bottom and a vacuum lines is attatched on the top. I believe you need a T-27 torx bit to remove it.
I would trace fuel lines from tank to fuel rail on motor. These are high pressure lines so do not try to quick-fix them. You will have to measure the lines and replace them if they are leaking. Unless the fuel is leaking from lines by fuel rail or by fuel filter.
