My 78 242 ran like absolute crap and I did a lot of troubleshooting for 3 months, never found the problem. Comprehensively ruled out fuel and spark problems. When I was pulling out all the unnecessary wires from the loom for my LS swap, I found the culprit. One wire was broken right where the main harness goes though the firewall, solid blue wire I think went to the Lambda system (hard to remember now). All the other wires looked perfect. So 1 broken wire could be your issue.
Before that, I had a lot of problems with the fuel pump relay burning up. I wired a modern 30A relay next to it to run the fuel pumps, just used the original relay to turn the new one on.
