I recently swaped out my 5sfe for a 3sgte engine, with harnesses and ecu and trans axels hubs, calibnurs and fuelpump, along with the radiator. Now when i crank the engine it does turn over but i have no spark nor pulse. I changed everything i could think of. The distributor, ignitor, ecu, coil, and i double checked the wiring harnesses. Anyone know what is wrong with my car.

did you splice the wiring harness on? or clip a 3sgte engine harness to a N/A body harness?

i'd just say check your connections, and your grounds first.

new cap, rotor, plug wires?
