that is pretty rare to blow up the ckp input, it is well protected, but that is good if you found ECU bad. they can be very expensive and testing them 100% is not easy.
it may be someone was wiring in some aftermarket part, to these ckp wires, for say , remote start or alarm and blew it up, (a humpy dumpty was pushed deal)
THANKS FOR THE FEED BACK, IT'S ALWAYS NICE. CHEERS
