645 is a/c clutch relay ckt, 1598 is a/c pressure sensor voltage too high, 1489 is high speed fan relay ckt, 1282 is fuel pump relay control ckt, and 1495 is leak detection pump solenoid ckt.
you should search on here for the factory service manual, download it and try to diagnose some of these codes. i don't want to jump to any conclusions but the common denominator is the ECU. i suppose you could have a bad 5v supply or something like that, maybe its grounded out. poor ground on those circuits? idk, good luck.
then again, it could be the crank sensor. and all these codes are just coincidence.
