This classic rolled up to me crank no start. Replaced distributor starts can wiggle pickup coil stalls. Get new distributor again. Ended up jb welding the pickup coil to distributor now it doesn’t stall when wiggling connector at distributor. But now it’s intermittent crank no start no spark. Using old snap on red brick no rpm signal when cranking.scoping pickup coil sensors I get 1 to -1 peak to peak volts. Is this pointing towards a pcm not recognizing the signal?
