Okay so recently swapped my high milage motor out that ran with a low mileage b20b. The car cranks but wont start. Fuel pump is not priming when key is turned over and I'm not getting any spark. I have a jumper harness for an 8pin to a 10pin harness on my dizzy and I did the ckf bypass for the no crankshaft sensor. The grounds are all good and the ground on the thermostat housing is good and tight. The ecu and fuel pump fuses are also good. I'm stumped any help would be great as the car had fuel and spark before motor swap.
