Guys, I'm hoping to gain a bit of help for a no-start condition I have on a swap I am doing in my 70 CST. Fuel pump is fine. I get plenty of gas to the rails. I have removed and replaced the injectors as the original ones were clogged. Next, I poured a bit of gas into the intake...not even a sputter. Then, I removed a spark plug...no spark. I'm inclined to think that the ECU isn't sending a signal. All wiring from custom harness is connected to the correct sensor/bank. No spark.

Any info is much appreciated!
