Good evening, PSN. I just replaced the water pump on my 2001 Ford F-250. During the install, I also replaced the coolant temperature sensor with an aftermarket from Advanced Auto Parts. Regardless, after putting humpty dumpty back together again, I cranked her up to make sure I had no leaks and she fired right up and everything looked good. However, after several minutes of warming up my temperature gauge wasn't moving and immediately, I knew I made a mistake with the aftermarket sensor. I shut her off to tighten down the battery connectors and take her for a spin to see if the temperature gauge would move at all. However, when I went to restart, it didn't even try to turn over. Everything looked and sounded the same when I turned the key over and waited for the light to go off, and when I turned it completely over, I heard an audible pop that seemed to come from the solenoid relay. Not sure, though. Any ideas what it could be and how best to troubleshoot? Thanks in advance!
