So last Monday my car overheated after stopping to get fuel. I had driven the car for about 45 mins prior to stopping. Originally I thought my csr pump went because I couldn't hear it run anymore. after installing a new meziere pump she still runs hot. also I cant hear the new pump running either... which makes me think its shorting out somewhere. its got a new relay. Thermostat still opens. anything im missing here?

Have you looked for actual flow in the radiator?

Did you check for 12 volts and a ground at the electric pump?

Ended up getting lucky. apparently the wiring for my old csr pump also had its own build in fuse, and of course it was hidden behind the radiator so I never noticed it was just a bad fuse haha... but I guess I have a spare pump now if it ever really does go bad. so to anyone still reading. always start with the small things. my 2 cents.

If you had checked for 12V at the pump, you would have found the problem without "getting lucky".
