Hot starts

After my car is at normal operating temp, sometimes when you shut the car off and try to start it within say 5 or 10 minutes it turns over at least twice as long before it starts. Should I be concerned? It's a 02 GT with a SCT 93 octane tune if that makes a difference.

We had a number of cars come in to the shop for this back when... The car never not started, nor did it run any differently..

I think the only car we were actually able to diagnose had a leaking PPRV (positive pressure relief valve) which let the fuel pressure leak down when the car was shut off, rather than hold it in the fuel rail

Personally I wouldn't worry about it

Re: Hot starts

That makes sense. We had to replace the fuel pump in the Edge due to that. The Edge did it all the time though not once and a while.
