Question about 2002 Oldsmobile Alero

5 Answers

2001 Aler wouldn't start

I got an 2001 Alero from my sister with what we thought was a fuel pump problem. So we tested the fuel pump with a battery and some test wires. it turned out that wasn't the problem at all. After that i read about a security system problem on line so i checked that and that isn't the problem. We tested the relay separately from the car the same way as the fuel pump. The relay works fine. after more testing we discovered that all the relays and fuses hooked witch receive power with the key aren't getting enough power to work properly. what could cause all this? The ignition switch is behind the entire dash so it is very hard to remove. Dose any one have any advice for me. As of now we are going to take out the ignition switch and test the power to and from it to determine what the problem is. Please help me some one.

    no, it just keeps turning over. Some times, it appears random to me, it will start and run fine like nothing is wrong. other times it will start and run for like 3 minutes then die and won't restart.

    i finally fixed it. i had bad information, it was the ignition switch all along. The points were arced and black. i cleaned them with a bit of sand paper, put it together and it started immediately. Thanks to every one for their help.

There is a common problem with the Oldsmobile Alero which involves a frustrating and intermittent power failure. A faulty wire leading from the fuel pump relay to the fuel pump was discovered by a very experienced mechanic on one of these cars after a consumer spent hundreds fighting with the car stalling periodically. A bad ground could involve just a broken or exposed insulation from a small wire or just corrosion at one end. You might try to use a replacement wire to jump around the faulty wiring OR hire someone to put the vehicle on a rack and trace the wiring with a tester all the way to the bad spot.

Could be a loose ground but all a relay does is a small wire controls a larger wire with more current flowing so it would be on the larger wire side.

Why won't my 2001 Alero (2.4) start?


The most likely causes on the Alero are either a clogged fuel filter (which should be replaced every 30,000 miles in order to avoid damage to the fuel pump), or a weak or bad fuel pump. I'd start with replacing the fuel pump since it's the cheapest fix, the part costs about $20 at the Auto Parts Store. Here's a link to the fuel filter location and replacement:

http://wiki.answers.com/Q/Where_is_the_fuel_filter_located_and_how_do_you_replace_it_on_a_2001_Oldsmobile_Alero

The fuel pump replacement is more work and more money. The part costs between $100 and $150 to buy nif your a DIY, or about $650 for parts & labor at a repair shop. The fuel pump is located inside the gas tank, so the gas tank will need to be dropped if the pump is to be replaced.

Could be any number of thing's . Testing before replacing parts eliminates waste . If you don't know how to test , your best bet would be to take it to a qualified repair shop that does. Electrical testing , fuel pump pressure an flow testing , hooking up a professional type scan tool to view engine sensor data parameters .

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

I'm thinking its the battery. Heat kills batteries. You said it wont jump start. That's a dead ringer for a bad battery. It may have enough juice to power some things, but wont run the starter, or the fuel pump, or the ignition(spark). Try a new battery and let me know!

Alero


it could possible be your fuel pump. If your fuel filter is going bad that want stop it from starting. I have a 2002 alero. I done have both fuel pump and fuel filter go bad. so i have a little experience with them.

2001 Oldsmobile Alero will not start. The car turns over but just will not start. Plugs are 4 mths old, tank is full of gas battery and alternator are working. Anybody out there know of anything we could...


you can also try pulling the fuel pump relay under the hood and put it back in. works on my 2000 alero. and yes if the security light is on, you need to turn the key on and wait about 10 min. until it stops flashing, then turn off, then start car.

Alero will crank awhile before it finally starts w/ more details


May have small fuel leak or fuel pump sending unit leak down. Or fuel pump psi low.

After 30 minutes try this turn key on. do not try to start wait 10 seconds turn key off then on again 10 seconds then try & start if it starts right away fuel system is losing PSI either back through the fuel pump or a leak in line. If you can find no leaks would suggest replace fuel pump & assembly.
Another possible but rare fuel injectors may be leaking fuel over time & dropping PSI needed for start up.
