04 mazda 6 2.3 auto no start
when i first crank the car i get injector pulse once, and a weak spark on one of the driver wires from the pcm to coil and a stronger spark on other side. i have a donor car and swapped pcm, tcm, cluster, key and lock cylinder(no security issues), coil, cmp sensor, ckp sensor and have done the short to ground and power tests, and the continuity tests over and over. the donor car runs but not this one. any ideas would be very helpful. someone believes this is a cali motor in a federal car but mazda dealer told me only difference is the cams and they are the same.
