Wont start when key in ing. and turning on than cutting off if battery dead


factory alarm, when manually unlocking the door the lights flash & horn usually go off & the car will start & shut off within a second or 2. Have 2 96 jeeps that do it the panic button on the keyless entry is the only way to shut it off. If the battery has died & a new one is installed it trips the panic mode as well. If the battery is dead but vehicle starts with a jump but shuts off soon after jumper cables are removed, the alternator is bad & cant keep the computer powered up & will shut down the vehicle. A little more specific with symptoms will make diagnosing much easier.

Clean the battery post's & give it a jump start, check that the alt is putting out 13.5 to 14 volts. If it's putting out less that 13 volts check the condition of the drive belt, good contact is a must for the alt to do it's job.If Belt is good & less than 13 volts alt is weak & cannot keep up with the load.

Battery Drain


It sounds like an Alternator problem.
Remember the Battery only Starts the vehicle and runs nominal operations. The Alternator actually provides the electricity to run the Engine operations. With that being said: Start the vehicle, jump start it if you have to. Remove the Negative Cable from the Battery or remove the jumper cables. If the Engine dies after doing this, the Alternaotr is bad and needs to be replaced. When the Alternator begins to die, it starts draining the Battery. During normal operation it is the Alternator that sends a small trickle charge back to the Battery keeping it charged-up.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

If the battery is bad and not holding a charge, every time you push on the brake's. The break lights come on and puts a load on the electrical system and if the voltage drops below 10.5 volts, the ECM will shut down fuel injector and ignition system. The other thing to is that the fuel pressure may be dropping due to the electric fuel pump not getting enough volts every time you put on the brakes. You cold always try keeping the jumper cables connected to make sure it's the voltage drop that is causing the engine to stall. Keep me posted, be glad to help you get your car running 1005 again soon.

98 chevy astro battery or alternator


Well, just for electrical basics coverage, the alt puts out volts and amps and it is possible for it to put out enough volts but not enough amps.

Best thing to do is to take the alt off and have it checked to see if it's putting out enough volts and amps.

If it is, then maybe the battery is shorted out and is drawing too much off the alt to allow it to run the vehicle.

I hope this helps
