Car won't start and arms alarm when I turn the ignition

Car got pretty soaked during Sandy. Three days later, battery is fully charged. First time, the car sounds like it's about to turn over. Second time, it gets weaker. Third time, no noise from the engine, and the alarm arms. Anyone know what this could be?

    I disconnected the battery and reconnected. I have to use a key to unlock the door, no keyless entry on my car (it's old!). Same thing happened. :(

Dead battery armed the security system. Remove the battery cable let the system reset. Charge the battery. Use the key to unlock the door instead of the keyless entry. This resets the alarm once the battery is charged.

SOURCE: trying to start the car

the battery may be fully charged but that doesn't mean that it doesn't have a weak cell, next time you go to start the engine remove all of the battery filler caps (if it has any) & get someone to look into the holes to see if they can see if any of the cells are bubbling,if any are the battery is faulty & needs to be replaced......hope this helps......cheers.
PS. don't get your eyes to close when looking into the holes of the battery,it might be safer to use a mirror.

turn the igntion on, don't start, let it set for ten minutes Turn it off for 5 seconds then try to start it. If it lost memory for some reason and doesn't start . then do this three times , after the third time start it. that is the relearn procedure. Have a charger on it for the 30 minute relearn. Relearn is on for ten m off five s on ten off five on ten off five then start

SOURCE: My battery is fully charged

Usually----- if you get absolutely nothing- you have a bad connection where the ground is connected to the frame or where the main (+) side is connected to the starter or the main fuse block.

I replaced the spark plug and ignition coil and now it won't start?


if the car won`t turn over then it could be a starter problem if the battery is as you say fully charged. check voltages at the starter. it could be a bad connection or starter relay.

2000 Jetta GLS 5 speed. I bought a new car, I went for a ride in it, drove and idled great. Went to start it later and alarm went off, it turned off after a minute but now the car wont start, battery...


This is a wild guess, but disconnect the positive terminal from your battery. Touch the cable (that went to the positive) to the negative, to drain out any capacitor in the system that is holding charge. I think you have to short it that way for about 10 seconds. Reconnect cable to positive and start car.

That will reset your computer and should reset the alarm as well.

92 Toyota 4runner truck was running perfectly fine Later in the day went to start and the alarm just started going off and wouldn't turn off. Truck won't start even with keys turned in igniti


The alarm system somehow got activated , this is usually because the battery becomes discharged or disconnected try doing this:
Remove the key from the ignition
disconnect the negative battery terminal
put the key back in and turn to ON
exit the truck and leave door open
reconnect the battery terminal
get in and leave door open, if the alarm horn stays off it should start.

1997 Lincoln Continentalhorn won't stop honking


First, Have your Battery tested. The Alarm systems in Ford made Products are very sensitive to Voltage. There are 3 systems in the car which interrupt power, the Alarm system (horn honking) and the Battery saver and finally the starter interlock system.

The Alarm system will do several things to disable the car from starting. It will reduce the voltage to the starter to prevent the engine from turning over. Some will even kill the ignition system so that if the starter is jumped, the car still won't start.

The Battery saver will disconnect any system to prevent discharge below a minimum threshold. Unfortunately, when the Alternator is working extra hard to charge a really bad battery: it will disconnect the charging circuit because it reads the Draw going to the Alternator to produce the power as a parasitic drain. Even at 70mph I have seen the charging disconnected and the vehicle coast to a stop when the electric runs out.

The last system worth mentioning is the Starter interlock. Under the dash and at the top of the Brake pedal lever is a switch. When you press the brake pedal, the switch allows the starter to crank provided the shifter is not in D or R. Drivers feet routinely hit this switch and either move it or break it. When it breaks it can short and drain the battery.

As you mentioned a Random problem, the Brake switch can shake to create a random problem if it is loose or broken. Your rear brake lights can be affected.

With the horn honking, at least part of your problem is the Alarm system. You can have a bad ignition switch too, which reads the keychip to disable the alarm. Your keychip may be bad and setting off the Alarm.

I had a new Lincoln myself which set off the Alarm randomly. I actually slept inside the car one night so I could turn off the alarm in the Apartment complex parking lot. Did'nt know if it would start again if the battery was disconnected and then reconnected. The Battery was shorted with less than 1000 miles on the car. It was a factory defective battery less than 3 months old.

But your car has many years and miles on it so it was worth mentioning the wear items. I hope my solution is helpful.

Key turns fine. Car won't turn on. Won't even crank. Sometimes pushing key further into the ignition switch with a bit of pressure helps. Battery is one year old.


What you are saying is the key switch is worn out, and there is a separate problem with the engine performance.
Either an import shop or the dealer are your options here.

1999 Dodge Durango LTS I had the battery charged when I installed it the battery gauge is not going all the way to 14. Car turns over but won't start.


First if the engine turns over but will not start then i woould check for spark at any of the sparkplugs and if you have spark then check your fuel pressure.If you don't have spark then you have an ignition problem.

I just buought a 98 Volvo S70 T5, the car sat for abit, to the point were It had to jump it. to start. ran great for the next 2 hours off and on mybe 7 diffrent starts but it never running for more then...


It could be a number of things:
  • Bad connection or corrosion on battery cables
  • Dead cell in the battery would prevent it from charging fully
  • Bad or worn drive belt would slip, preventing the alternator from fully charging the battery
  • Bad alternator
If the car will run at idle with all accessories turned on, the alternator is good and you should concentrate on the battery and battery cables. If the car won't idle, then the drive belt and/or alternator could be the issue. If the car starts everytime when it's cold and only gives you a problem starting when the engine is hot, the starter could be the issue. A bad starter will often work when it's cold (after sitting a few hours or overnight). When a bad starter gets hot, it takes more and more power to get it to turn over.
Overall, I'd have the electrical system checked out. Most chain auto parts stores (Autozone, Advance Auto) will do a complimentary electrical test for you.
