We just got back from a long trip with the Trailblazer. We drove from Shreveport, LA to Columbia, SC and back a week ago. Since we have been back, we have noticed that the truck had been getting harder and harder to start. When turning the engine over, it would get slower and slower, until eventually one morning, it wouldnt start. We put the jumper on the battery and it started up. Throughout the day it was hard to start, but it did. I put a trickle charge on it overnight and in the morning, cranked right up.
Well, I took a trip to Dallas yesterday (3-4 hours away) and did a bunch of running around there. I noticed that the truck was getting harder and harder to start, so at my last stop I just left the truck running. After driving to that stop, doing what I had to do there, and then driving home, the truck had been running for about 4.5 hours. I pulled up in the driveway when I got home last night and shut the truck off. I immediately tried to turn it back on, and all it did was click really fast and the dash lights blinked right along with the clicking.
I put the trickle charge on it over night, and it cranked right up in the morning. This is when I noticed that I had a fuel leak at the pressure regulator, so while I had the truck down doing that job, I figured I'd tackle the charging issue.
I took both the battery and the alternator to Autozone for them to test. They tested the alternator as good, but their battery tester was down. So I went down the road to Advance Auto and they tested the battery as good, but their alternator tester was down. So, I went to Oreilly, and they tested BOTH as good.
One guy at Oreilly said their may be a fuse that blew that is not allowing the alternator to charge the battery.
I'm about to go outside in the 100+ degree heat and check all the fuses, but wanted to post this beforehand to get some feedback.
Any and all help would be GREATY appreciated. I have to get this fixed. BTW, removing the alternator....PITA! Thanks GM!
