OK.. so this will be like the 10th time explaining this, but I will not skip over anything.
Bought the car May12th.. drove it for 3 days.. the weekend came and I decided to do some repairs.
The motor mounts were bad, I changed those, as well as the spark plugs, wires, oil, oil filter, and tightened up a few loose / missing bolts here and there.
Everything was fine.. the engine started up and ran.
I noticed I forgot to reinstall this bracket the holds the Crankshaft position sensor connector (where it plugs into the wiring harness)
I turned the car off, disconnected the crankshaft position sensor connector (to have clearance to install the bracket)
I did NOT plug the crankshaft position sensor back in, and obviously the car refused to start.
I double checked everything and found that the CKS was unplugged.. the guys on the Mazda forum said if I plug it back in, everything should be fine.
I plugged it back and and no start.. I disconnected the negative terminal on the battery, pumped the brakes a few times, and left it unhooked for 24 hours to make sure the computer reset.
24 hrs later, no start.
I hooked up to jumper cables to be sure I had enough power.. no start
I replaced the crankshaft position sensor, and went through the reset proceedure again.. no start
I pulled all the plugs and double checked gaps and it looked like inside the combustion chamber was damp (getting fuel) and on top of that I felt like I could smell it a little bit too.
Now I took the car to the shop.. they said the OBD2 scanner is reading the computer so the ECU isn't dead.. they said they "think" its a bad crankshaft position sensor. (I already purchased and VERY carefully installed a new CKS that I got from a reputable online seller)
The shop wasn't sounding super enthusiastic about working on this car (they had it for 3 days) and barely touched it..
SO I towed it home today.. I have now noticed a sporadic power situation where the dash lights / power seems like its running on a dead battery and other times, the power seems good.
I will take the battery to get checked.. but anything ringing a bell for anyone?
