in my 95 z28 there was a short in the power drivers seat. so if you have a power seat unplug that. it was a problem in the 93 to 95.
========================================
i got a 94 too. the clock and radio run after you take the key out until you open the door. Even if the clock stays on the whole time, it probably isn't enough to drain your battery. have somebody with a wand check it for shorts, you might also just need a new battery.
Headlights run off the battery not the ignition...
The voltage reg is sticking and will run down the battery.
If the ignition switch is faulty it could leave an electrical component turned on and that could potentially cause a dead battery. That would not necessarily be the case and you might notice if the switch is supposed to be off but something still runs.
The radio time would stay on if you had the keys in the ignition but the ignition was only turned halfway.
either a dead starter or a bad ignition coil would be my guess
It sounds like your ignition timing timing is too far advanced. It will need resetting.
Answer: Most likely battery (you probably surmised this already), however, it could also be a faulty ignition switch or poor connection at the starter or starter module/relay. When the key is turned, do the instrument cluster warning lights come on (& dim slightly)? If so, its not the battery.
It could be a bad battery.
The clock in a car may reset when the ignition is turned off if there is an issue with the clock's power source or a problem with the clock itself. It could be due to a blown fuse, a malfunctioning clock module, or a weak connection to the battery. Checking these components may help resolve the issue.
Could be your battery, starter, ignition, check them... would start with the battery !
A malfunctioning the ignition switch will allow the car to keep running after the key is turned off. You can remove the positive ground cable from the battery to shut the car off.
I had the same problem. I had been using a very poor battery that was almost flat all of the time. All battery connections turned out to be in good order, worried about the engine begining to seize up hbut found it turned freely by hand. the problem turned out to be the starter motor that had broken down due to constant use of a poor battery condition. Please check your battery condition, connections, that engine turns freely and your starter motor. A lot of garages do a start and charge check very cheaply.
