Problem Starting
After I've been driving for a while (20 minutes or more) and go to shut it down and let it idle for about 30 seconds, I go back within 15 minutes to drive it again, and it acts like it's flooded. It won't start unless I push the gas pedal to the floor. Any ideas or is this normal?

I'm with AzEKnightz; have a shop (or you) hook up a fuel pressure gauge to your return line and key up with engine off. after priming the fuel pump for two seconds, it will shut off. observe the fuel pressure, and it should hold pressure, not bleed down. 1-2 psi of bleed off is okay after about a half hour. this will tell you if you have an injector leaking...then it is up to you to determine which one (and for this i REALLY would not follow the instructions in the service manual...'cause it sounds very dangerous)

so I took it to a shop to get the compression test, and I told them what the problem is, and they said it didn't sound like a compression issue cuz the car starts fine when it's been sitting for a while. I also noticed yesterday while driving it that if it sits for less than five minutes and I go back to start it it starts almost like normal. But anything more than five minutes or less than an hour or so it will crank, but not turn over the first time or two that I turn the key. I also noticed that if I sit there with the car's electrical systems on for like a minute before I start it, it starts up as if it's only been sitting for a minute or two.

ok, I got it compression and fuel pressure tested, here's the results
Front rotor compression: 100 psi
Rear rotor compression: 105 psi
Fuel pressure: within spec but drops 5 psi after 15 minutes and then holds steady
any ideas?

If they did it right, they should have provided you with 6 numbers.

yeah, he only gave me the two numbers, ****, i'll call them tomorrow, it's a place here in town that's called economy and performance auto service, so I'm assuming they didn't do it right, ****, now I want my money back!

ok, really late on the update on this. got the compression numbers, 100 psi all faces front, 105 psi all faces back.
thought I had a coolant leak as it smelled like I had coolant burning when i ran it hard, but when i topped off the coolant level and was checking it constantly, like once a day before driving it, the coolant never dropped.
so i think it's a injector getting stuck open, does this sound right? cuz it's still having really hard warm starts.

i had the same problem as you and my buddy gave me a tip about hot starts. before i would turn off the car hold the gas at 1500 to 2000 rpm for a couple seconds and as i turned the car off push the gas pedal all the way in while shutting down. i never had an issue with hot starts ever again.

that's what I thought, but if it's flooding cuz the injectors are getting stuck open, then maybe this will work.
No, I haven't I'll see what I can do when I get her back from the shop, getting a new clutch, flywheel and pressure plate installed!

If it isnt puffing a huge ploom of black smoke on starut than it likely isnt the injector sticking, sounds more like a compression issue to me. I have seen injectors get stuck and then begin working normal again but it never had anything to do with engine temps or how long the engine ran. The few I have seen get stuck usually start working again if the car is taken up to about 4-5k rpms.

really late update, got a new FPR and solenoid put in, still didn't solve the issue, and compression fine last I checked, but I could always get it checked again. Coolant levels have been fine, haven't had to add a drop in a few months, any other ideas? I can take a video of it too. I've contemplated sea-foaming it and seeing if that helps any.
