Sometimes this is caused by a bad crank position sensor.
Have the codes retrieved (at autozone or any national parts stores for free) and see if that points to anything. If no codes are present, it could be the crank sensor-which a mechanic could test before replacing.

SOURCE: 2003 Oldsmobile Alero will not start. Already

I have a 2003 alero that would not start. It was actually a security problem it locks itself up, there is a quick fix for it though you turn the car to the on position wait 10 min. turn it off for 5 sec. and then turn it over and it should start. Sounds to easy right, thats what I thought someone found it out for me online before I had to throw a bunch of money into it, like others have. HOPEFULLY this will work for you too.

2002 Old ALERO drove home find didn't start later turned over fine but didn't fire replaced fule pump about 2 months ago


Pull a plug wire , set the end close to the engine, crank it and watch for spark. No spark could be the cranks sensor, wires, ignition module , fuse, or PCM. Have the codes read. Could be the fuel pump too. I have had them die shortly after installs.

2004 olds alero. new fuel filter and plugs. still wont start.


Did you check for spark at any ot the spark plug wires/ coils? If there is, check for fuel pressure at the fuel rail. Take the port cap off and connect a fuel pressure gauge. If one is not available, with a pocket screw driver deppress valve at port and observe if fuel pours out. If no fuel comes out at all, check your fuel pump circuit. Check for good ground and power at fuel pump connector. If power/ground are ok, replace fuel pump. If spark and good fuel pressure is present, there is the possibility of engine mechanical issues(jumped) timing chain). Also, a plugged catalitic wont let engine start but its very unlikely thats your problem. Start with your basics: spark, fuel, engine mechanical and catalitic.

If you have no fuel pressure and the fuses are good chances are the fuel pump has failed. It is located in the fuel tank. You have to remove the fuel tank to replace it. Replace the fuel filter to.
