Ok i need some help i tried to search this problem before posting but... i came up with nothing! I have a 93 talon with a 5 speed its bone stock well the problem is after driving it for a few minutes it begins to spit and sputter then i here a clicking sound from under the dash and the car stalls when i try to restart it, it will turn over but wont start back up.... im getting fuel and spark but still wont start......but when i put a fresh battery in the car it will fire right up and run good for a few minutes and then does the same thing again....this problem has me stumped any ideas?

I would check out the alternator. Sound like it is not keeping up with outout needs of the engine. This would explain why the new battery would run the car for a few minutes then die out. Also, while you are looking, check to make sure the battery terminals are tight and all the ground wires around the battery are tight and intact

It would take more then a couple of min to run a battery down.. My buddy drove for a 45 min hwy run on a bad alternator after that he need to recharge it. While its running pull the terminal off the positive side of the battery that will tell you if the alternator is generating any power..

NO! This can spike the system and blow the ECU! http://www.dsmtuners.com/forums/pro...-battery-alternator-question.html#post1763645.
Just measure battery voltage with engine running and headlights on to see if alt is putting out - should be > 13.5V. (14.4V is normal output with evrything else ok).

Learn something new everyday... I did it that way and had no issues... But i have to admit if i know that before hand, i would not have tried it.

I have tested the alternator and its not that its testing 14.4v on the battery...

Pull the ecu and check the caps. They have more than likely leaked and damaged the board.

Ditto captain. Easy cheap fix though, all you need is Ebay, 5 bucks, a soldering iron, and a q tip with some acetone to clean off the old nasty acid that leaked out.

Sure. Most people dont have a spare ecu laying around to throw in the car.
