Parked my car one night, the next morning it only clicks, bought new battery, cranks and stops running suddenly, now no start again. Engine cooling fan relay burned and the circuit board melted where it inserts. OBDII finds P0101 and P0763 and that's it. This has a new motor 2 years ago after crankshaft pulley busted it. It doesn't seem that these codes include any circuit issues or similar related to this issue. Would it even be worth fixing? The engine has less than 25,000 miles on it but I wonder about the garage that installed it. I'm not so sure they put in a new one like they charged for.
Would the relay issue be related to the codes and if not how do I find out what caused it?
