Hot Start Issue, please help, need to smog soon and need to know what to fix
Hey all this is my first post on this form, so hopefully you can help!
So I have a 2002 S2000, with about 90K miles on it.
I have a hot start issue as the title says. When I drive my car around for a bit, and I turn off the engine, it fails to start up a lot of the time (been happening more and more often), specifically when it's hot out. Now if I wait about 10-15 mins, I can get it to start, put I do have to put down the gas.
My mechanic things it's the fuel pump, which it could be (as of the past couple of days I've been hearing a little gargling).
I've also read that it could be the main relay on some other sites (reddit).
Have any of you had this problem as I'm describing, and if so, what was the problem, and how much did it cost you to fix?
I have to get the car snogged by December 1st, so any help would be appreciated!
Thanks in advance guys!

Could also be a failing Fuel Pressure Regulator. A dummy test you can do to see if the diaphragm is leaking is to pull the vent line off the pressure regulator and crank the engine over. If liquid gas comes out that vent line you know the FPR is bad.
I've never had this issue on an S2000, but same thing happened on my Cavalier years ago and this is what it ended up being.

Locate FPR on your fuel rail. There will be a small diameter vent line coming off the top of it going into your intake manifold. Pull the line off the FPR and try and start the engine. If liquid gas comes out that line/port, your FPR is bad. (The diaphragm is torn) If no gas comes out then it's good (it's supposed to only allow fuel vapors into the intake manifold, but when they go bad, liquid gas will go past the diaphragm)
