99 300m Dies at just under half a tank.

It sounds like the float setting changed when you hit the pothole. You could open it up and set the float but the best method may just be a new carb.

Is the check engine light on, and have you checked the computer for trouble codes ?

Give use any codes you may have

I have a 2004 LS I will check my diagnostic
manuals for you

V6 or V8 ?

Check under hood for a vacuum hose off,broken, cracked or loose at a connector.

when theengine dies the oil light will come on did you run out of gas

Well first it should only restart in park or nuetral, any check engine light on? May be fuel pump if not. Listen for pump running in fuel tank. Should run at key on for a few seconds. If check engine light on, it should be scanned for codes, possible crank sensor

The EGR valve will not opon when the engine warms up so that is why it dies out

run engine until problem occurs. turn engine off or let it die. leave key on but don't start engine. put a paper clip in diagnostic plug under steering column. look at area on dash where service engine soon flashes. count flashes. (ex. 1flash-1,1 flashes=1,2. if you see 1flash of service engine soon, then 5 flashes in a row the diagnostic check = 1,5. It will flash this several times in a row. this is your code. look it up or ask and find out what it is. this is usually your problem area. let the car tell you.

i bought a 2005 sebring and they gave me 2 keys. one grey and thick. the other black and less heavy. the black one will start the car but as soon as i take it out of park it dies. the grey key has a chip in it that sends a signal to the engine. The black one doesn't. it is more like a back up key so that if you lock your other key in the car and it also unlocks doors and trunk.

If you turn the ignition on and off 3 times the ce light will flash trouble codes.
