    I have the same problem. I have limited funds with lay-offs and it is my only car. Where can I read up on the processes of elimination so I can learn how to do the things that you suggest myself. Do I need special tools...Thanks, Tim...

    I also have an 03 Alero and was driving it home the other day when I lost all power and it died... the engine also will turn over, but it won't start. I am thinking that it is the timing belt, but I am not sure... also on a budget since I just lost my job. Need to get it fixed asap so I can go to interview

    2003 alero 2.2L wont crank sometimes, never a problem in the morning, but after i drive it and cut the car off, then it starts acting like it is flooded or not enough fuel. it started doing this when i drove the car very hard (120+mph) and also lost control, fish tailed and the driver rear end bumped a pretty high embankment. When i finaly get it to crank if i let off the gas pedal it will cut off, but if i apply brake + gas pedal and shift into gear it wont cut off. if i rev the rpms pretty high (4000 - 5000) in park it sputters ? Please help i dont have the money to throw away!

Check to make sure the Security light in dash on right hand corner is not on. If it is on , your passlock is enabled. to dissable it turn your key on but not start it and wait for apx 10-15 minutes. this should re-set it.

If the engine turns over, but just doesn't start, you need to do some checking, check for spark from the coil, or coil packs, if that checks out ok, have the crank and cam shaft position sensors checked, timing belt, computor. I know it's a pain, but I have worked on cars for 40 years, something like this you have to use process of elimination, without testing, you could replace things you don't need. ( expensive) good luck).

My car was running fine and out of nowhere it just shut off and it wont start back


The same thing happened to my 03 olds Alero, i pluged my scan tool in and found out that my fuel pump was bad, I changed the fuel pump, fuel filter, and also checked the fuel injectors and blew out the fuel lines, now it's running great.

I bet it's the gas. After some time the gas will no longer be volatile enough to start the car. Try draining all the fuel and putting in some fresh gas. Remember, when you try to start it again you'll need to get the new gas through the pump and lines before it will start. Also, check the condition of the injectors. Old gas can start to break down and build up a film that could be on your injectors (or clog your fuel filter- better check that too). Hope this helps.

2002 alero turns over wont stay started sudden problem


It sounds like it may be the fuel pump. Have someone turn the ignition key to the 'On' position (don't start car) and listen to hear if you have a whining coming from your fuel tank. If not, your pump is bad. If that's not the culprit, then check your gas. You may have had a bad fill up. Try adding some octane boost to your gas and changing your fuel filter.

Truck stopped running as I was driving and won't attemp to cranck.


wont turn over or wont start, if it wont turn over your alternator probably came unpluged or went out then drained your battery, if it turns over but wont start you lost the timing chain

I have a 2003 stratus and it wont start... Crank sensor???


In a HOT day,old battery and fuel pump will be the prime troublemaker.

You need to charge up the battery and check for 12.4-13.6V range.

How old is the battery?

Most are warrenty for 24,48 or 96 months.

====
Fuel pump motor portion will ran forever. But the plastic diaphragm will give out in a hot day.

Do a fuel injector pressure test. Below 40 pis is trouble.

Fuel filter should be change if the fuel pump is at fault.


ALL more gas until it's over 1/2 tank and re-test.

A weak fuel pump will take more effort to pull fuel from a near empty tank.

Good luck,
