This is my first post.
My brother has a 2005 Chevy Trailblazer LS with the 4.2 L6 engine. Over the past several months, he has told me of times when the car would not start. He said he would try every couple of minutes until it did start. It never took more than 3 or 4 tries. I cannot remember if the car would crank or not. I know at the time I was thinking it was the starter going bad. Just this past Thursday, 2/15/2024, I finally replaced the starter after he was stranded for nearly 30 minutes before the car would start.
The trailblazer started, allowing me to pull it into my garage. When I finished installing the new starter, the car would not start. I even put in the old starter to see if I had ordered a faulty starter, but all the car did was crank over. Occasionally, it would sound as if it was starting but putter out when I let go of the key. It seemed to me that it was not getting enough gas. However, I tried starter fluid a couple times to no avail. I know it's not the fuel pump relay because I swapped it with the horn relay which are identical. I tried jumping it but got nowhere with that. I even bought a new battery. This was all Thursday.
I left the battery completely disconnected overnight and, in the morning, I connected the battery and tried to start the trailblazer. It started up on the first, albeit it ran a little rough at first but settled out. I did not move it. I kept it in park. I let it run for a few minutes before shutting it off and trying to start it again. Nothing. It refused to start back up and would only crank. It sounded like it wanted to turn over but just would not. I tried starter fluid again but got nothing.
I left the battery disconnected again overnight and Saturday morning I tried starting it again and it started. The same thing happened where it ran a little rough but settled out. I let it go a couple minutes before shutting it off and trying to start it and it refused to turn over. I tried leaving the battery disconnected for a period of half an hour and then for an hour and it would only crank after each time period.
I bought a spark plug spark tester and a gauge to test the fuel pressure but just have not been able to test either yet. Any suggestions as to what it could be would be greatly appreciated.
