Question about 2002 Oldsmobile Alero
I started my car, and it took a few minutes to get it started, it is louder than it was and shakes. The check engine light is flashing. I had my battery tested and it says it is near the end of it's life. We had to tap the alternator to get it running but we took the battery cables off the battery and the car remains running. Please Help!
Flashing check engine means shut off the car immediately, engine or catalytic convertor damage if you keep the car runnning . Never disconnect the battery from a running car it can fry the alternator. Sounds like a spark plug or ignition coil or ignition wire problem.

SOURCE: think alternator is bad
can you get a jump start and drive the car to autozone for a charging system test ? then you are right there if they tell you the alternater is bad .

the flashing check engine light is indicating a misfire. if you can't get it scanned for codes, start with the obvious, check plugs, wires, and coil packs first.

It could be the inertia switch has malfunctioned. Try that first, it is cheaper. The inertia switch is basically a tool to keep your car safe in case of an accident. I am not sure where yours it. In my truck it is below the glove box, in my old car it was in the trunk. Try pressing it once and see if it starts, or hold it down and have someone start it. If that doesn't work, it could be the fuel pump is bad. Take it to a trustworthy mechanic, not the dealership or Pep Boys/Big O. The big companies just want to take all your money, trustworthy mechanics want repeat business, I have found.

Sometimes you have to wait a week for the light to go off, the computer has to go through several start/run/stop cycles.

I have an 98 Olds. Intrigue and had the same exact problem. I replaced the alternator and worked for about two weeks and then one morning did not start, jump start the car and drove it all day, it was like that for another week until I drove it at night. 10 blocks form the house the lights dimmed out and the car died. I towed it back home and worked on it for two days. the problem ended up being the alternator plug. Not all the wires had a tight connection. I pulled the wires from the connector made the necessary adjustments and put the wires back in. Plugged the connector into alternator and my problem was gone.
I had some other cases of Intrigues Buick and Grand Prix with the 3800 engine with different problems. So If the plug is OK, check the following:
CHARGE INDICATOR LIGHT ALWAYS ON
Good Luck!! Keep me posted!
