I had a same type of problem on my 80' zx.
it turned out to be a combination of deposites on the distributor lugs and a defective high tension wire. I could actully see the sparks jumping from
the distributor to the negative input terminal on the distributor. If you have an DMM(ohm meter)
measure the high tension wire, it shoul be around 5000 ohms, not any higher. Also either replace the cap or if not to pitte or simply remove the deposits with a knife.

Stuart, you said that your fuel pressure was good
(3/4 full). You need to check it with a pressure guage, and i would do a volume test at the same time, to make sure it has the proper amount of fuel available at the injectors. Also, I would buy a noid light, about $10.00 at snap on, or Mac tools, to test the injector pulse.
Please feel free to call, if you have any questions. Thanks, Joe

I just got my 78 280 running this past weekend.
Here's what I did. After checking the plugs(all of them), I pulled the no.6 injector and it was working too. I just assumed that all of them were working. After being dumbfounded I put a test light to the plug going to the injectors(to check for a pulse) I couldn't get a pulse at the other 5. Someone told me it was the computer. So I changed that. Then I was told that the AFM always goes out. So I changed that. After talking to all of the world's foremost authority type of people, I proceded to pull the entire fuel rail that feeds the injectors. When I did that I found that only 2 of the injectors were working (and barely at that). Instead of going out and buying six injectors(at $40 a pop, screw that)I pulled each injector and figured out that 2 didn't have good connections and 2 were clogged. I cleaned up all of the connections and gave each one an enima. Take an air compressor and blow air through the injector (reverse flow). Have a buddy hold the air on the injector and, using a 12v source, open each one until you see the air come out the input side. Low and behold the **** thing ran. Remember the mechanical part of the engine only needs three things to start: air, gas, and timed spark.

Hope this helps out it worked for me(sorry so long)
