OK my 2000 blazer has been a nightmare after taking ownership of it I chased down a number of problems the largest being replacing the BCM and PCM. After that everything was fine. Now in the last few weeks out of nowhere it wont start it trys but it will not fire. If I let it sit for an hour it will start just fine, then a few days later it wont start again. When it wont start it acts like its flooding. While it is runnig it runs great. Im thinking either a bad coil or the pressure regulator. One other question I have is I dont have the key fobs for it. Is there anyway to disable the alarm so when I unlock it the horn stops blowing?
