2003 Chev Cavalier 140K suddenly acted like it wasn't getting gas. I put it in park and was able to rev the engine but when I put it in drive I had the same problem. Went into the store came out and the car would start but would die right away. I tried to hit the gas but it was like it wasn't getting any. No lights came on so where would you start? Fuel filter or pump or neither?

check vaccum lines. inspect throttle cable and spring. if cable is warren can stop it from releasing all the way

Hi Cindy,need to check and see if the belt is turning tightly,they may have not done it,to check,open hood,start engine,leave in park,go to engine,find accelerator cable and rev up gas and see if belts are turning tightly,or have someone rev gas in car and someone watch.Also look around engine to see if they let something out of place,you never know these days,even at dealers.

is the engine light on or any other light on, on the dash board. engine may be in limp mode limits the revs and put engine is standard setting. cam and crank sensor fail one of them will put engine in this mode when they fail.

The neutral safety switch will not let you crank the engine in anything but park and neutral. If something happens to the shift cable the trans may still be in drive.

(Not a mechanic) First thing to check is the transmission fluid level. If excessivly low it may not move. (Usually check trans fluid with transmission dip stick, while engine is idling and warmed up) Consult owners manual to verify procedure. If your fluid levels are normal or close to normal, you should call a transmission shop unless you are or know a good mechanic.

Possible low fuel pressure. Should be 31-35 depending on which engine you have. Check to see what you have.

I encountered a similar problem on a chev 4cyl with a coil pack ignition ( no distributor). It would run for a while and suddenly die out and wouldn't restart until a 10 to 20 min. cooling period. It turned out to be a crankshaft position sensor going bad. On this engine it was located in the engine block under the ignition module on the firewall side.

This problem can be several things. When your engine is cold, your computer is in a "closed loop" and just pretty much keeps the engine running until warmed up. After reaching operation temperature, the computer starts reading all the sensors. If one sensor is not connected or is defective, you will experience performance problems. Most of the time this will turn on the check engine light, but not always. Second is the fuel pump. This too will cause erratic engine problems.

Have you checked to make sure the catylitic convertor isn"t plugged? Disconnect the exhaust and rev the engine is there a difference? Good Luck!

might wanna check ur throtle position sensor
