    Hi you didn't say you had already had this done .Well check the fuel pressure could be a weak fuel pump or dirt clogging up the fuel pump screen. Hope this helps and good luck.

Cant find the crank position sensor in 2000 alero

Check that the cam shaft is turning as it may have broken a timing belt. Run fault codes to check for cam/crank position sensor problems.

I have a chevy s10 2.2 2003 truck and one day it ran about five miles. then stalled. it started back up idled fine but put it in gear. stalled again. had to get towed home replaced the fuel filter,truck...

When you press on the gas when the truck is running, does it rev up?

Did it die while driving down the road (foot on the accelerator) or when idle? - If so, try cranking it and get your RPMs up to 1500-2000 RPMs and put it in drive (with your other foot on the brake). See if it will continue running if you never take your foot off the gas.

Dies when going down the road. Pull over and it restarts again. Usually when going uphill. If I don't let the fuel drop below 3/4 full it doesn't die. Could it be the fuel cap?

Remove the fuel cap and drive the same route as you did when it stalls. If it don't stall the fuel cap vent is plugged. Get a new gas cap.

If it does stall, I would suspect the fuel pump hose to the top of the unit has a hole in it. Allow the fuel level to get below the point where it stall and check the fuel pressure. Should be 55 to 62 at key up and hold. If it drops the possibility of a hoe is there.

1999 olds alero stalls when put in gear

Runs fine when not put in gear? Sounds like transmission is stuck in "lock-up". Need to go to transmission or full automotive shop for repair. This is not something you want to attempt on your own unless you are experienced with removing valve bodies and solenoids from the inside of transmissions.

Loses power on steep grade

Sounds like you need a clutch replacement.

Try this. Go somplace where there are no cars, and no possibility of running into anything. Stop the car. Set the park brake. With the engine running, put the vehicle in 1st gear. Hold the foot brake pedal, and give it gas, and let out the clutch slowly.
If the engine does not stall real quick, the clutch disc is bad.
