So, I was taking my dog to the dog park and the car has been driving great. I shut the car off and when I return in 45 minutes or so, it wont start.
The car turns over, but nothing happens. This has happened before about a month ago. The car was running great, then when we came back out, it wouldn't start. I left it there for a few hours and came back and it started right up and has driven perfect since.
I have added a ranger header, removed the intake silencer, and installed 17lb injectors since that time, but the car runs like a top.
I have no idea what it can be. It is getting spark. I can hear the fuel pump priming, and the timing belt seems to be ok. No check engine light.
I will go back tonight and see if she starts (try to re-do what happened last time).
Please help with any ideas?

So, I went back last night and it started right up and I drove it home with no problems. Any body have any ideas?

You say it has spark.? Does it have spark when it wont start? If it does then you have a fuel delivery problem. All it takes is 3 things to have an engine run. 1 spark strong and at the right time 2 fuel at the right time and proper amount. 3 compression at or above 130 psi cranking . When the engine wont start it is clearly a heat issue.When the car cools down it starts. This tells me you are probably loosing spark? Check it when it wont start and repost. TOM

i've had a lot of ignition coil issues like that. a lot of time the coil is dying and won't give spark when hot. check the spark when car won't start and motor is hot. no spak, probably the coil.
