I have the following codes;
P0300, P0325, P0421, P1569, P1250, P0660 and P0715. All related to circuit malfunction including multiple misfire. All started happening after water pump blew and was replaced. Already did full tuneup and replaced coil packs so that's not the issue. Also noticed that the radiator fan isn't turning on. Have not tested the fan motor yet.
I'm thinking wire harness or PCM issue. Anyone else ever seen this and know what's up? Any help is greatly appreciated.
