I have a 1999 Pontiac Grand Prix GT V6 3.8Liter. Yesterday my gas tank was a little below so I go to put regular unleaded gas into it. I drove it home fine with no problems at all. After about an hour I leave my house and drive it about a mile down the street when the car just randomly turns off. In order for me to start it back, I had to hold down the gas pedal. Now today it won't even start and when it does I have to floor the gas pedal...there is a strong smell of gas and my car sounds like an old car when it does start up. What could possibly be the problem and how much does it cost to get fixed?

You need to check the fuel filter when it checks out. Check the fuel pressure, pressure in specs.

When it won't start disconnect a plug wire and ground it to the engine while cranking it over, Do you have spark-Got spark-next step is to look for fuel-crank engine and listen to the injector/s are they clicking and do you smell fuel in the throttle body. Do this and comeback

Now check the actual pressure with gauge-could be wrong pressure-pressure checks out-We'll do the valve and igntion timing -

Disconnect a spark plugwire and ground it to the engine while cranking engine over-Do you have spark?

If your smelling fuel, it could be that your fuel pressure regulator has gone bad and is dumping to much fuel causing a rich mixture. this would cause the conditions that you explained.
