2003 Cavalier LS 73,000 won't start

If it,s got a distributor the condensation will have formed under the care move cap and spray with WD40. then spray all the electrical parts to do with the ign.coil etc spark plug,s.and leads.Wipe out cap with rag.

Too much trans fluid would not prevent it from going into gear. Do you have a check engine light on? This is probably going to be expensive. Get it to a transmission shop.

Check for spark and fuel. When you turn the key on you should hear the fuel pump in the tank for a few seconds till the pressure builds up. When you crank the engine there should be spark at the plugs.

sounds like she jumped her timing..might be a mechanic job....sorry

CHECK FUEL PUMP FUSE AND RELAY.IF BOTH GOOD.YOUR FUEL FILTER STOPPED UP OR FUEL PUMP GONE.BUT FIRST HOOK CAR TO SCANNER TO SEE WHAT CODES IS BEFORE SPENDING A LOT OF MONEY.

the most common cause of this is loss of the fuel pump pressure

Ignition control Module out again? Over energized?

there is no fuel pump cut off switch on this car, it is possible the fuel pump module was damaged from this accident, u will have to have the fuel pump circuit tested for faults before replacing the pump, don't guess, this is an expensive repair

replace the crankshaft postion sensor.

check and see if you are getting fuel at the fuel rail. the is a technical service bulletin for no start concerning the fuel strainer. the 03 came with a 100 micron strainer which clogs causing a no start problem due to low fuel pressure. should be 40to50 psi.
you can try tapping the fuel tank with a rubber mallet sometime that will getting the fuel pump working temporalily. also check the ignition module on top of the coil packs this part controls the spark. hope this helps
