Hot starting issues

Has anyone figured out why our cars don't start or start hard when hot. Car will start fine when cold. Tried searching and never found out what the issue really is. Anyone have the answer. Heard to replace the battery, starter, or crank sensor.

explain... the worst I have encountered and isnt often is I shut the car off after a drive and immediattly turned it and the car took longer to fire up. (Starter spun a lot longer). Again doesn't happen that often to me so im just asking what your situation has been like?

After driving the car and go to start it again, the car won't start up always on the first try. It will just crank. The second time I try, it fires right up. I've read it could be the starter is heat soaked. If i let the car cool down a while, it will start fine. There is a bunch of posts about this, but never found the correct fix.

The AC Delco starter gets heat soaked with headers. I've replaced it and even added heat shield, but after a while it has the issue again. Might want to look into other brands if you replace. I definitely will.

If your modded like that... you need a modded starter.

Call Powermaster and talk to their tech dept. They have top notch stuff and will steer you to the right one.

You're also fighting the drop off from the really long battery cables. Makes the need for a really good battery and starter that much more.

I went through all kinds of different starters on my BBC drag car. When I finally went to a Powermaster Ultra... all problems stopped. Doesn't even need a heat shield. There are a few other top quality brands too.

If you have access to your tune also, make sure the cranking timing isn't too advanced.

yep. I get this problem. Struggles to start, then when it does fire up, throws the TC/ST lights, tach doesn't work, and get the 'Service Stabilitrac' warning.

I've looked everywhere, and decided that it's the starter getting too hot. I am considering having my headers ceramic coated, but in order to avoid the down time for that, I'm going to get either a new hood, or some hex vents to [hopefully] reduce engine bay temps.

If that doesn't help (and I'll know sometime this summer, bc it gets pretty warm here) I'll figure out the best starter for a replacement.

My headers are ceramic coated, but your issue is a bit different, because I don't receive the warnings

Mine has shorty headers and is a L99, would the same issue be true for mine? When I'm running and the vehicle gets hot this happens. However, mine also idles rough after warning up especially in warm weather. Is this related?

Just called powermaster and asked which starter for my car. He said the 9509xs. Found them on eBay for $206 and free shipping. Going to order one right now. The guy said the solenoid is encapsuled so there shouldn't be any heat soak issues. Will update after I install it and see if that takes care of the problem. Thanx Russel James.

Might wanna check your cam position sensor too. Mine was hard to start on occasion and found the cam sensor harness rubbing against the block and shorting out my sensor intermittently.

I have the same issue. Besides a weak battery in the summer do to a higher resistance with temp, and so much music in my car. When the car was hot and shut off between a few mins to an hr it would not turn on or i would take a few seconds to fire. Very annoying, and taxing on the starter to say the least. It is a definite temperature related issue. It only happens after the car was hot or running a while. It cold be super cold and the car always fired up. I am definitely going to change my starter into a much better unit. Thank you guys.

I had the exact same thing happen to me over the weekend after driving around all day. My headers are ceramic coated though...

I installed my new starter, but haven't gotten a chance to drive my car again. The weather turned shitty and snowed again. As soon as it's gets nice out, I will update on the results of the new starter.

Any up date with the starter? I have been having the same problem for a while. I installed a new battery and checked all wires and grounds, but no luck.

Manny, I started a thread about this issue last week, OP commented that the starter he replaced it with, so far has fixed the issue! Another guy just replaced his starter with the OEM starter this weekend, so far has fixed his issue as well. I am going to replace mine as well.

I have a similar problem and when I took it in they told me its the fuel pump. He went on to say that many of the 2010 and 2011 camaros have this problem. I was told that GM was supposed to recall the pumps but felt that it wasn't a major issue. Hope this helps.

I have the same issue when I was i. Florida and still have it in texas. I assumed it was the heat causing it but since it doesn't do it all the time hard to replicate for someone knows what to look for
