Hi! The anti theft might be triggered during the battery removal. Try this, Put the key in the ignition and turn it on forward position just before where you crank the engine. Dont start the engine, just leave it on for atleast 12mins. This should let the fuel pump running. After 12mins turn off the car and remove the key from the ignition. Insert the key again to the ignition and wait for atleast 11seconds and try to turn on the engine. Hope this helps and have a good one!

Clicking under the hood, dashboard lights keep flashing. Wont start!

Try this. It sounds like you need to reset the ECM (engine control module) and the anti-theft system.

Resetting a Vehicle Anti-Theft System
This is how you reset an anti theft system if you have the anti-theft light on, or your car is cranking, but you have no spark.

Doing a full reset of the anti-theft system.

Disconnect both battery leads for at least two hours.
Hold the negative and positive leads together for 5 minutes to fully discharge any power.
Put the key in the ignition, but not turned on. VERY IMPORTANT!
Connect the positive lead.
Connect the negative lead in one swift movement.
Wait 15 minutes for the system to fully reset.

Car wont start after pulling out the spark plug leads and then attempting to start as an anti theft procedure. could be a electronic distributor malfunction?

You pulled the wires to test anti theft. Or pulled them to see if there was spark because of anti theft? Year make and model helps. Older cars did kill the spark. Newer ones on kill the fuel.

Why would my 01 honda turn over but wont start

if your car has anti-theft on it when the battery went dead it signalled the computer that someone was trying to steal the car. you will have to reset the anti-theft system to start your car. if you don`t then recheck what you did changing the battery make sure all the wires are connected properly.

Anti theft wont let me start car

I would treat it as a general no start condition. It could be fuel or ignition. The anti-theft system would prevent it from starting but not kill the engine once it has started.
Check the fuel pressure with a gauge and watch the spark at the plugs.

Car starts but wont stay started

If this is the same car with the tdm question, the anti-theft system will prevent the car from starting AND cranking.
You will need to find out if you are loosing fuel pressure or spark to the plugs to proceed.

2004 ford explorer will not turn over with key but remote starter switch makes it turn over

Its a good possibility that the Anti-theft is interferring with the circuit. If you have an extra ignition key, use that in case the password chip in your regular FOB has detriorated.

There is a brake sensor which is on the upper brake pedal. It interlocks with the starter to prevent starting without having your foot on the brake pedal. Check your brake lights for operation. If the brake lights stay dark with your foot on the pedal, the switch is broke or knocked out of position. A common problem.

Next, there are small wires for the starter solenoid. You can use a test light on one removed wire and ground the test light to the vehicle, the other end in the small wire. Turn the keyswitch to start, with brake pedal pressed and see if it lights up. If it does light up, the starter solenoid may be bad.

Battery level. Ford Anti-theft and some say Battery-saver, can cause both starting and charging problems. A fully charged battery can be at 13.2V- 13.6V. When Ford systems detect low voltage it can activate the Anti-theft, battery-saver, and even disconnect the charging system to allow the battery to completely drain. In some cases the Anti-theft drops starter voltage to around 7V so the starter will not spin. Have the battery tested.

I know of 2004 trucks that were jump started and showed charging, then after 5-10 minutes they lost the charging system. Some people lost the charging system at 70MPH and drove until they stalled. All because of the automatic features built into the trucks. A new battery fixed the problem. Your problem could stem from this.

Changed out original battery. reconnect shows tiny sparking. everything works. no bad fuses. will not turn over. thanks

It's possible the sudden loss of power (removing old battery) has triggered the anti theft system. Try using your key and physically unlocking the driver's door. In most cases, this will disarm the anti theft system.

I have a 1997 dodge ram with a 318 engine. Engine will not start . It will try to fire for a secong but stalls . also sound s like it is not firing on all cylinders. The only time it will fire is if you...

Check if equipped for anti theft system. Usually the anti theft will allow for initial spark and then kill the fuel injectors!
Disconnect the battery and have it recharged and tested, if it fails the test replace it. Use the key and manually lock and unlock the drivers door if the alarm is still set, There is a switch attached to the door lock that disables the anti theft. If the driver's side is defective switch you have to do this from the passenger door.

Hope this helps?

Truch is cranking but not turning over to start. Battery & alternaotr seem fine.

You mean the truck is cranking over but not starting? There are 3 things that prevent your truck from starting. Fuel??? Spark???? Air?? One more thing would be an anti-theft device that you forgot about. Check the 3 things above and find out which one is missing. If you have all 3 and no anti theft device, your problem lies deep in the computer controlled stuff.
