1991 Ford Escort Engine won't turnover

Electrical problem
1991 Ford Escort 4 cyl Two Wheel Drive Manual

Car was experiencing jerky acceleration so I performed compression tests on the cylinders per manual instructions. Only disconnected spark plug wires and ECS plug so engine wouldn't start while checking compression. Compresession checked ok and engine was cranking fine. Came back later to try other test, but engine didn't crank, dash lights on, headlights worked etc. Assumed battery had gone dead during compression checks so attempted to jump start car. No joy. Installed new battery, no joy. Jump started WITH new battery no joy. Haven't attempted to start it by pushing it and engageing clutch for lack of assistance. There is no sound when the key is turned to start, dashboard lights all on, a few relay clicks here and there, but no starter engagement or cranking. Nothing. Rechecked electrical connections multiple times, all connections are in place.
