Not a definite cure, but what comes to mind is that one or more injectors may be leaking fuel into cylinders after you shut it down. Does it run a bit rough for a second or two or do you get a puff of black smoke after it fires up when you get re-started? Aside from taking the injectors out and cleaning or replacing them you could try using 3oz of acetone to 10 gal of fuel for at least the next four fill-ups. If it's not too bad, this usually clears up fouling.(acetone will not damage the system... I've used it for about three yrs now.

1991 chevy lumina wont start after sitting when you drive it


Just because you replaced the fuel pressure regulator does not mean it is working correctly; which is the most common cause of your problem. Hook up a fuel pressure guage and watch what happens when you are starting it cold - it should go up to about 47 PSI and once started it should read between 40-47 PSI, then when you turn the engine off: Does the pressure drop? There is a check valve built into the fuel pump also; that can be faulty and if the pressure is generally reading low and the check valve is bad- this can also create your problem. We have run into this before also; When the fuel pump is cold the internal pump seals are sealing great, but after a period of running time the pump seals lose sealing power and if you try to start it again it will be hard to start. The biggest thing with this situation is getting the fuel pressure readings at the following points of time:: Start-up, running cold, running at normal operating temp, engine off, engine re-start.

Quits after warm up wont restart


sounds like you have a fuel pump problem, fuel pumps will usually get hot and then shut off allowing it to sit 30 mins lets the pump cool down allowing it to start pumping, the way you can test it is get a can of starting fluid the next time it quits raise your hood and spray some fluid down into the throttle body and if it starts and then dies it is most likely your fuel pump, hope this helps.

2004 pt cruiser won't start sometimes after you


Good chance fuel pump is getting hot and has to cool down before pumping back up to required pressure. I had to test fuel pressure when cool, then when hot to catch drop in pressure. Are you having any problems with how far you can drive before it quits, or starts to get sluggish?
