My 2000 Oldsmobile Alero does not start. It cranks fine, has a new battery, new spark plugs, and I can hear the fuel pump working. I was thinking of checking the fuel filter next. Much help needed

Do you have spark at plugs when it will not crank and run ?

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.

pull one sparkplug and crank the engine to see if you are getting spark. then check to see if there is fuel getting to the injectors, without fuel and spark at the right time an engine won't run

my sister in-laws did the exact same thing. we replaced fuel filter pump and injectors. All the time it was old spark plugs. It kept cranking but wouldn't start. spent less than $20 on new spark plugs and it fired right up and is still running strong

These cars are notorious for failing antitheft systems. Your symptoms sounds very similar. Read thru this link and compare your problem to described one.

fuel pump relay or fuse to the relay

make sure your cap and rotor timing is correct double check spark plug routes (mistakes happen). maybe your timing is off in general.

if car wont start.make sure your battery volts are 12.5.if not charge battery.or replace it if dont hold a charge.if battery is good engine wont turn over.make sure battery cables is clean and tight if all good no start .have starter and starter solenoid check.if battery and starter is good.check for fuel .has some one turn ignition to the on position.go to rear of car listen for fuel pump noise.if your hear fuel pump check ignition system for spark.go to auto parts place buy a spark tester.if you get no spark .check .ignition fuses and ignition module.if you hear no fuel pump.replace relay or fuse.if if fuse and relay good replace fuel pump.if every thing good .your car could have crank sensor problem. or your car is in theft deterrant mode.if so have your car towed in and scanned.

Do you hear the fuel pump make a whirrring sound when you turn the key to the on position ? You should be able to hear it. If not , the fuel **** is not working. Check the shutoff valve and see if the reset button is up. If it is up, press it down and try to hear the pump again when you turn the key to "on\'. If the shutoff is OK, but you don\'t hear the fuel pump. Replace the fuel pump.

check the housing onder the manifold and the converter they might be clugged up and keeping it from starting right away.
