    Yes it will crank when hot and sometimes will start but will not stay running unless the RPM's are at 2 to 3 k

    Don't know where that is located. The motor will crank when hot and will sometimes start but won't stay running.

Hard Start When Cold 01 Bucik Regal

Did you check the fuel pump relay ?
You would need to use a fuel pressure gauge and check pressure before you crank the engine.
When you turn the key switch on, the pump relay is supposed to provide power for 3 seconds to boost fuel pressure.
If fuel pressure is ok, the coolant temp sensor could be telling the computer the engine is warmer than it really is.

When car is cold starts right up, after driving for short distances, few miles, won't start, have to wait an hour and then it will start. It turns over, but not getting gas, is it a fuel system problem? It...

I have the same problem. Started in 2001. I got lucky and pulled the fuel pump relay, then stuck it back in and it started. I replaced that relay and it worked fine for 7-8 years. Now I am experiencing the same problem. Another forum I read suggested during a cold start, the fuel pump works from the circuit breaker, but after the car is heated up, it works frm the oil pressure? (I didn't understand it) but it went on to say that as the car heats up, the oil thins down and the car won't start. It didn't mention a fix for this. Just try the relay. It's about $30. Maybe they just get weak?

4 cyl Engine starts and idles ok...give it throttle and it dies

I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?
