It is a known issue. Fuel pumps can work, but not provide enough pressure, so you need to test with a pressure gauge. There is also a Pressure Regulator. Have a read of this.

Try Changing the fuel filter, if this does not work check for spark. Hope this helps you.

It might be the starter or solenoid going bad.

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.

im pretty sure its your timing belt

its either fuel or spark. Check the plugs to see if they are fouled out (dirty). Replace if necessary

start by checking for spark, then check fuel pressure and injector signal, so you need a spark tester and noid light

well if you security light is on, then you have to put your key in the on position for exactly 10 mins and wait until the light blinks and then turns of and then you turn the key off and they you can start it. i have a 2002 alero and it works for my car.
