I know that there’s no way to 100% accurately diagnose a problem over the internet, but I’m hoping to get some sound advise so that I can decrease my chances of being taken advantage of by a mechanic that I’m unfamiliar with.
For the past few weeks, my '99 Saturn SL1 has been having starting issues. This typically only happens in the late afternoon/evening after I’ve already started and driven it 2 or 3 times in the day. It always starts up fine first thing in the morning. However, later in the day, it simply won’t start. The engine turns as long as I’m turning the key, but it won’t fire up. Sometimes the engine finally fires up after about 3 tries, but most times I have to give it about 30 min - 1 hr to wait. I try it again after waiting, and it the engine starts just fine.
Also, this only seems to happen once a day. After finally getting the engine to start, I can turn it off and start it a dozen more times, and there will be no problems.
I’ve already had the electronic temperature sensor replaced, and the problem persists.
No warning lights come on when I drive, and an Autozone employee tested my battery and alternator and said they were fine. This has only happened for the past few weeks, so I haven’t noticed any other major symptoms, although there could be something I’m just not paying attention to.
Thanks for the help! I know I always wind up paying more than I should mechanic shops because I just don’t have enough car knowledge to know any better, so I need all the advice I can get!
