86 Pontiac Trans AM mileage 140000, Hi, my car was running fine after swapping the engine then one day it stalled at a light and since then will not start, I checked timing, fuel pressure, and trouble codes nothing seemed wrong, I have spark at all eight cylinders, but when it does start it seems like only 2 or three are actually firing. I did an entire tune up but nothing has helped. What should I do?

You need a "noid" light to test for injector pulse at the injectors
