Ya know.... in 20 years of T3 driving Ive never had a problem with a hot start... I think he has a problem, if it were vapor lock or something characteristic of our FI Id think I would have had an issue with it at some time. I agree with Jim that the fuel lines need to be good, if there over 10 years old the need to be replaced anyway, but if 30PSI doenst push fuel through a hole I doubt 15PSI of air would get through. Id stick a pressure gauge on it... see whats really happening, then maybe you have an intermittant in the motor, do you hear it try to run when the car doesnt start? If properly working, the FI should be "issue less" Keith > > I took a drive this weekend about 40 miles, all > > highway. When I stopped for about ten minutes, > > the car wouldn't start again.
