Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

It can be done but it is very time consuming.
I use an 87 Astro van intake sensors and computer on my 86 OMC.
After six years I am still playing with it.
Runs good and easy on gas.
Got lots of info from DIY-EFI.
You HAVE to change programing in the computer.
I am running a closed loop system with one oxygen sensor in the starboard manifold.
Your 94 computer is not as good for a boat because it also controls the transmission.
Just to give you an idea what your in for.

Check your coil output, buy a cheep spark tester. Pull of a spark plug wire and plug in the tester(ground the other end), set it to bridge a gap for 30,000 volts.Have someone start it and make sure the spark will jump the gap on the tester.Danger-Very high voltage! It will light you up if your touching the tester while the car is running!You'll be able to see a bright blue spark(and hear it as well) if your coil is good.If it's a yellow thin spark it's probably the coil.
If you have good spark, check the fuel filter and fuel pressure at the fuel rail.
Back firing could be timing,cam position or crank position sensor.Worst case scenario, timing chain or belt.
