Cranks ok. No start. Tach sort of floats up to 1k then back down to stall. Has happened 5 times in the last 2 weeks. Run into a store for a few minutes, hop back in, crank, no start. Every time the outside temp was pretty hot 90+. Let the car sit for an hour or so, then it starts up & runs fine (usually by the time AAA shows up). First I thought maybe vapor lock. Let the gas cap vent for a bit. No luck. Happened 3 times last weekend, then I had it towed into the dealer. No Trouble Found. Drove the car (mostly highway) all week. Ran a can of gas treatment/cleaner through + 2 tanks of high test. Car ran fine. No hesitation. Mostly highway, 2 hr+ duration. Got to this past Sunday, ran to the store for ten minutes. Same thing. Had it towed back into the dealer.
Dealer seems clueless. No computer codes showing any faults. They've just had it sitting there, running it, trying to get it to not start. They had the thing for 2 days last week. This week it's been there since Monday. Can't duplicate it. Car starts fine. Dealership has put me in a loaner for now, but I have a feeling I'm going to get the old "NTF" tomorrow.
First trouble since it rolled off the lot 3 years ago.
