Oil levels and color was good.

Changed the oil sensor on back of engine, and had to take off the fuel rack, gas lines, coil harnesses, injector harnesses just to get my sausage fingers to the oil sensor

When I went to start the car, it would go into accessory mode, but won’t start. It wouldn’t even attempt to crank, and just made a clicking sound.

Battery reads good, no corrosion around terminals, just replaced the starter, fuses are all good, swapped relays and they all work, all harnesses I had taken off are all connected. Engine isn’t seized

I am stumped. Any ideals anyone can think of????

Any CEL?
