I also have some thoughts on my hot-start issue. I am now suspecting that I may have a leaky injector, which would cause the system to lose pressure when shut down. This would also, if I understand it correctly, flood the intake port of the leaking injector(s), causing it to be difficult to start. It always starts hot with the gas pedal to the floor - ie, throttle wide open - adding extra air to the system, right?

So, I need to check fuel pressure. Is there an off-the-shelf kit I can buy, or do I need some specialized tools to perform this test?

Thank you!
