I had the same problem. It may start to or already is stalling as you slow down or stop. I changed my fuel pressure switch located right on the fuel rail on top of the motor. It's about $80.

Without seeing it it is a hard thing to diagnose. You could have an injector leaking, possibly a fuel line. Do you smell gas? Sometimes with fords around the fuel filter leaks because of a broken clamp. The o rings around the fuel injectors could be leaking, or one of the rubber fuel lines. If you go off road alot, you could have a pin hole in one of the rubber or metal lines. Check and get back with me and I will do the best I can to help. Hope tis helps.

Gas would leak out of a cold, hard, rubber fuel line. When the car warms up, the rubber line swells and seals itself up until it gets cold and leaks`again. Find that leaky fuel line asap or you're risking an engine compartment fire every time your car is started, when it's cold out.

When i start my car and let it warm up for 5 minutes it smells like gas every morning only? What could it be?

someone who is qualified and trained needs to look at the fuel injection system. you are either building fuel up as it sits idle all night or the cold fuel enrichment needs an adjustment. both would cause the smell of unburned gas after an overnight sit.

Sounds like you have either a bad fuel pump or a leak in the line somewhere. With a leak in the line it will take a long time for the gas to get up toward the engine. When it sits over night the gas line empties back into the tank and the process starts all over again

I have a 96 Jimmy 4.3 vortec engine. When it's cold it sometimes doesn't want to start and seems to be flooding, when you let it sit for an hour or so it will start right up. Once you get it started it...

Sounds like one of two problems, The first would be a sticking throttle plate, you can fix this if you did the things you mentioned above to do so all you need to do is get to the throttle plate and with carburetor cleaner or top engine cleaner you can buy from any GM dealer Use a tooth brush to clean the throttle plate inside and outside and the ring the plate after you get it clean put it t gether and start it and get it warm next pull a hose feeding into the intake and put it in the can of Top engine cleaner and allow the cleaner to be sucked into the engine until it is all in the engine and shut off and let sit for 20 minutes. The start it up and run it till it's running smoothly now run it for the day and let it sit over night, try starting it, if it does you found the problem and fixed it if it does not start then do this push the throttle plate down to the floor and hold and crank over if it starts your set if it still has the gas smell in the morning check the cold start valve and see if gas is running out of it if it is then the cold start valve may have to be replaced. you also need to check the engine one more time and see if the EGR valve is sticking open after it turns off and cools down. Hope this helps thanks for using fix-ya and write back if you need more help.

It may be due to a failed/faulty fuel pressure regulator. I had this problem: easy start when cold, hard starting when warm/hot, and rotten egg smell from exhaust when warm/hot. My mechanic diagnosed a failed/faulty fuel pressure regulator, replaced it, and now the problems (warm hard start, smell) are gone. I have a '92 GT with L4 engine.
