Battery went flat, I charged battery, and now it won't start, fire.

Here are trouble shooting tips.
Most common answers you will hear, are it's the battery old or you may just need to check and clean the terminals for a good connection. Can take battery to local car parts place and have them check it.
Alternator - but if you have headlights working and they are not real dim its probably not.
Starter - but if the engine is cranking, prob. not.

Audi A6 2000 wont start

you have lost the immobilizer code. have you tried ignition to number 2 with lights on and press fob to lock then unlock doors. then try to start the engine. a flat battery for to long can wipe the code of the fob and ecu link if the battery has been off or flat for a to long period. only way to repair lost codes is a tec2 and your pass code for your vehicle. and if you dont have the pass code it can cost a fair bit to get the code from a dealer as they keep them on file for years then they get put back to back up after then and can take a bit of finding. if you battery in the future if you have a battery fail its best to put a good battery on again as soon as posible to stop this happening again.

1990 corolla cranks fine but won't start. What is the troubleshooting process?

check to see if the timing belt is still moving the cams. you should be able to remove a couple of bolts on the top of the timing cover and pull the cover back far enough to see the belt.

You can also look in the oil fill cap, you may be able to see the cam.

you can also remove the distributor cap to see if the rotor is turning.

If the belt is fine than check for spark and fuel pressure.

My bet is the timing belt. Especially if the engine sounds like it is turning over faster than normal.

2000 volkswagen beetle has trouble starting. Warning Light came on showing a key. battery is fine and alternater is good. could the key need to be programed again for the computer system?

You have an electronic immobilizer key recognition problem. Your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel. Do you have this warning symbol lightning on the dashboard?


This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

Use another ignition key that you have, and start the engine.

You will need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

Ran over immobilizer gadget for a 2000 toyota corolla. Now the car won't start what can i do?

2000 its aftermarket two ways remove the alarm and do away with it or find the switch to turn it off its either a small red button you press as you crank to start the engine or its a small micro switch. Better yet remove it. go under the dash you will have to remove the panel to access the relay find where the aftermarket alarm installer spliced into the ignition switch follow the wire colors thhere cut it and restore it back the way it was two colors from ignition will now match there use a but connection or solder the wire back together and wrap electrical tape to protect it from shorting out.or you can just drive it to a shop that know how to repair and remove the alarm you need two person . some one in the car and someone direct the starter by jumping the solenoid to battery with thhe ignition in the on position and someone in the vehicle so it doesnt take off and run you over

2000 Buick Lesabre. I parked the car about 6 months ago because I bought a newer car. When I tried to start again the starter gets no power. There is an odd electrical problem because things like the vent...

The immobilizer has come on you need to diss arm it or bypass it.This some times happens when the battery is left flat for long periods of time.

Car starts with remote starter. The start procedure with key?

Well, it sounds like your ignition switch is bad or the remote starter you have also has an alarm with a starter immobilizer. Do you have the owners manual to your remote starter? If not you can always remove the immobilizer part of the alarm by hooking the start wire back together from the ignition switch that is cut when you hook it up.

2000 Toyota Corolla wont start Changed 02 sensor disconnected bat

that red LED is the Alarm, if its solid red, its fine; blinking is about to trigger I think and off means the Alarm is active and opening a door will set it off.

as to why it wont start...not a clue,
check gas, make sure its in park,
you said its turning over but not firing, perhaps its a bad sparkplug or just flooded...

1999 Volvo V70 wont start

I had the same problem with the 2000 v70 XC I bought in Dec. 08. I replaced the battery, then the antenna ring (around ignition; part of the immobilizer system), and bought new keys as sometimes the chips in them do go bad. Also, if you have a key for another car with an immobilizer system on the same keyring, take it off. The multiple signals can confuse the immobilizer system. I think the antenna ring may have been one issue as, consistent with what repairpal stated, I got a crank and the engined turned over for about a second or 2 one time and then it died. The antenna ring (and the new keys) were relatively inexpensive. That worked for about a month and then I got no crank at all.  I had the starter replaced, but in hindsight I think that may have not been the problem.  I think the problem was the starter not getting juice. The starter was a very expensive solution. About 2 weeks after having the starter replaced, it wouldn't crank again.  I took it to a Volvo dealership and gave them the history. They found a corroded wire near the starter and, at least until now, that seems to have done the trick. Labor on the wire was about $100 at the dealer. Searching Volvo forums for those who have had a similar problem, I have found that others have had the "bad wire" problem.  If you are told to replace the starter by your mechanic, my advice to anyone having this problem is to have check to make sure the starter is getting juice before replacing the starter as replacing the starter (parts and labor) cost me about $650-$700.  If they find that the starter is not getting juice, they can check for wire corrision starting at the starter and working their way back.
