My 94 V6 wont stay started, it ran well last night but today i try to start it and it will fire up but then die. Any idea what the problem is?

 

Does it sputter then die, or just shut off as if you're turning of the key? If your car an automatic or 5-speed?

 

Need more info. kinda hard to answer a question like this. Is there a check engine light on? if so whats the code? hows the battery? whats its voltage at? when was the last tune up?

im going to say that your battery is dead because your alternator most likely wasnt charging it last night. but before you replace your alternator you should check your battery with a volt meter and make sure its at 12v. if its bellow 12v then you need to charge your battery then try starting it and make sure once the engine is running that it reaches 14v. if it doesnt then you have a faut somewhere in the charging system. if it does then theres something wrong in one of the many other systems
