2.8L LE V6, FWD, 1988 Pontiac Grand Prix LE.

No problems with it ever since I had 2 injectors replaced on it along with the ECM unit and Prom chip (all done last month).  Saturday I started it in the morning, drove around doing errands for about an hour, went home.

In the afternoon, I go to start it and the engine does not even turn over!  Just a 'CLICK'.  So I think 'BATTERY'.  Get the jumper battery pack out of the trunk and try to jump it.  It starts.  I take the pack off and open the door and the engine cuts.

Turn the key again and - 'CLICK'.  So I go get the jumper battery pack out of the other car, try to jump it, engine turns over once and then 'CLICK'!!!!!!!!


I think 'ALTERNATOR' cause it apparently cannot hold a charge.  I replaced the alternator.  I then jump it with jumper battery pack and it starts and is running fine.  I go to take the battery pack o ff and the engine cuts!!!!

I take the battery out of the car and charge it.  Battery charger indicated it was at full charge in about 10 minutes!!!  The battery is apparently fine, the car is just not starting/idling!!!

After full charge of the battery, I put it back into car and the engine goes 'RRRRR' (turns over about 1/2 way) and nothing!

Are you sure this is an electrical problem?  If the charger showed full charge after 10 minutes, then it wasn't very drained.  If the car doesn't have a voltmeter in the dash, then buy a cheap multimeter from Home Depot or something to verify voltage.

No, I am not sure this is an electrical problem.  I am not sure what the heck kind of problem this is!

And yes, I agree on your statement that the battery was not drained- especially after only charging for 10 minutes?!?!

The thing is, when I turn the key to start the car, it goes 'CLICK' and all lights are dim after that.  Then wait a few minutes, the lights are bright again.  Electric dash does the same thing (dims and actually turns off.)

Maybe take the battery to a local auto parts store... they'll usually load-test the battery for free.

Do you think that could be the problem?  The battery does not have enough starting amps?

Battery was just replaced in December.
