Iwas driving my 1999 alero n it studdered for a second. I gave it some gas nand managed to drive one block before it died. I tried to start it but it won't start it turned over but that is all it did

Check your fuel pressure it should be 60-66 psi with key on engine off.If its not within these specs then replace the fuel pump and filter.Sounds like the pump might be weak.

try the spare key and see what happens ,if no spare then call out a auto locksmith and have one made and the keys reprogrammed but it scould be you lost the chip out of the key or its been wiped by a mobile phone or a TV screen even a body scanner or any electrical field

You have an injector leaking,or most likely a pressure regulator leaking.

check your fuel filter it could be restricted that won't show up on test. A faulty fuel pump wont show up either...next time it stalls check to see if you can hear the pump running when you turn the key on. (filter may be part of the regulator on top of the pump unit on top but outside the tank)

Defective fuel pump or cloged fuel filter,

You will have to go to the old way of finding out where to start locating the problemm. Gas supply or ignition ( spark) problem. What was missing when it quit.? Gas or spark or water.

• see if you can hear the fuel pump click over when you turn it to start position! this may be a fuel pump?

check air flow duct where the throttle valve is . check the pvc valve . make sure it isnt stuck open. check the egr valve . it will stick open stall out motor .use a scanner it will tell you if you got egr valve problems. check fuel pressure. it could be stop up fuel filter bad fuel pump fuel pump relay.your car problem sound like a major vacuum leak . change spark plug and wires if they have not been change in a while. it could idle air control. hook a scanner .it could give you a code.

Hello!
I've only got a small portion of your problem up to started back up with a???
I am guessing Catalytic Converter failure? if this collapses or blocks up it restricts the exhaust gasses causing far too much back pressure sometimes resulting in backfiring and really poor performance.
Hope this FixYaZ problem!
Good Luck,

need to have the alternator tested sounds like a bad voltage regulator.
