Ok, so my m52 swap was running perfectly. Started every single time, and the coolant system works perfectly.
I unplugged the ECU because it started giving some funky codes, and when I plugged it back in, the starter wouldn't crank at all. Thought the battery suddenly died, but I tried to jumpstart it and it still didn't do anything. Kerrath and I push started my car, drove around the block a couple times, came back, and it started just fine. No more codes.
It was good for a couple days, but then another strange issue started. The coolant gauge would read high while the engine was running. It would look like I was going to overheat, but when I pulled over and shut off the engine, and turn the key on, it would read dead nuts at thermostat temp (75 degrees). My efan switch is at 80 degrees, and it wasn't on, so I decided to let me car idle into the "red". As soon as it touched the red, the fan turned on. So red was actually ~80 degrees. Turned off the car, turned the key on, and it was half, which is normal. I assumed it was the gauge coolant temp sensor, but being a thermistor, I can't imagine running vs. not running would have any effect on it's signal. Something else must be wrong.
So I've been nervously driving around for a couple days, pulling over a few miles to make sure I'm not actually overheating. Guess what problem came back? The starter won't really work anymore. Sometimes if I held the key on the "start" position, it would click a couple times and finally catch and start up just fine. The starter is pretty much unresponsive now.
So I'm thinking maybe there is a weird ground issue, or maybe the starter is just (going) bad, but that doesn't explain the coolant gauge. I dunno WTF's going on. Any ideas?
