The factory alarm system seems to be preventing the ignition from starting, there is a overhead small globe like ball between the driver and passenger seats on the overhead above the shift console seems to controle something that prevents the car from starting and if it does start and drive, when I shut it off it won't restart. Paid $475.00 to have fuel pump replaced by mechanic who swore that was the problem. Now it sits in front of his shop. ??? He has no answers, help

It sounds like there may be an issue with the factory car alarm system on your 1996 Toyota Camry that is preventing the car from starting. If the alarm system is preventing the starter from getting power, it is likely that the alarm system will need to be repaired or replaced in order for the car to start.
If the Toyota dealership does not have the parts or knowledge to repair the old alarm system, it may be difficult to find someone who can fix it. One option you could try is contacting a specialist who works on older car alarms and see if they have any experience with the alarm system in your Toyota Camry. Another option is to try finding a used factory car alarm from a wrecker or online that is compatible with your car and installing it to see if that resolves the issue.
If you are unable to repair or replace the factory car alarm, you may need to consider installing a new aftermarket car alarm system. An aftermarket car alarm can be purchased from an automotive parts store or online, and a mechanic or an experienced car enthusiast should be able to install it for you.

Does it crank and not start or won't crank at all? If it won't crank at all then the starter or solenoid that fires it could be defective. Also if it won't crank could be the neutral safety switch in the transmission keeping it from starting. Is there an alarm on this car? Alarms (especially aftermarket ones) usually have a starter interrupt circuit that prevents the ignition switch from activating the starter when they are set. Factory alarms may prevent the ignition system from firing if they are set or defective. Anyone been doing "non-standard" wiring under the dash recently??? Check that first then check the large gauge wiring connections, starter, ignition switch wiring and alarm(s) in that order and you should find your problem. This issue can be fairly simple but can also quickly turn into an complicated electrical troubleshooting nitemare. You may want to consider having it towed to a reputable shop for professional attention.

The steering lock may be binding the ignition lock cyl preventing the key from turning or the key may be worn out. Try turning the steering wheel back and forth while wiggling and turning the ignition key. To get the alarm to turn off without starting the car try locking and unlocking the vehicle from the passenger side door. There is a micro switch on the drivers side door lock cyl that may be bad and preventing the alarm from dis arming. This is all providing it is a toyota factory alarm sys.

The factory alarm is tied into your ignition switch. Most newer vehicles have an anti start system incorporated into this in case it is broken into. The alarm will shut the system down and will not allow the vehicle to start. Look under the dash under the driver side and see if you can locate a small box. Should have a serial number barcode on it. If so it has a factory alarm.

Starting System
The function of the starting system is to crank the engine at a speed fast enough to allow the engine to start. Heavy cables, connectors and switches are used in the system because of the large currents required.
The starting system consists of a gear reduced starter motor, battery, remote control switch (ignition switch) and relay.
Vehicles equipped with automatic transaxle have a transmission range sensor attached to the circuit which prevents operation of the starter motor unless NEUTRAL or PARK are selected.
Vehicles equipped with a manual transaxle have a start inhibit switch in the starter control circuit, which prevents operation of the starter motor unless the clutch pedal is in the applied position.
------------------------------------------------------------------------------
The anti - theft protection system provides protection from unauthorized entry into the passenger compartment.
The system is controlled by an anti - theft alarm control. When armed, unauthorized entry into the vehicle is detected by lamp switches.
Once triggered, the system flashes the headlamps, the parking lamps, the alarm indicator, and sounds the horn. In addition, the starter circuit is disabled to prevent starting the vehicle until the system is disarmed.
System Arming
The system will be armed by the remote entry transmitter when the following input sequence is followed:

1. Turn the ignition switch off and remove the key.

1. Close all doors (unlocked).

1. Press the LOCK button on a transmitter to lock doors. Alarm warning lamp will turn on.

1. Wait for the anti - theft warning lamp to turn off.

The system will also be armed when the following input sequence is followed:

1. Turn the ignition switch off and remove the key.

1. Open a door. Alarm warning lamp will flash.

1. Lock doors with power door switches. Alarm warning lamp will now glow steadily.

1. Close all doors.

1. Wait for the anti - theft warning lamp to turn off.

Opening any door will activate the alarm after the alarm is armed.
Disarming an Untriggered System
The system can be disarmed by performing one of the following procedures.

• Driver or RH front door is unlocked with a key.
• Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.
• If remaining in the vehicle, turn the ignition switch to ON or ACC position.

System Triggering
The armed alarm system will be triggered if any door is opened without using a key or a remote entry transmitter to unlock the door first.
Disarming a Triggered System
Carry out either of the following steps will disarm the triggered alarm system.

• Driver or RH front door is unlocked with a key.
• Driver door is unlocked by pressing the UNLOCK button of a remote entry transmitter.

Two minutes and 45 seconds after the system has been triggered, the horns and exterior lamps will shut off automatically. The system will then reset to an armed state and will trigger again if another intrusion occurs.

Passive Anti-Theft System (PATS)
The Passive Anti-Theft System (PATS), known as SecuriLock, is fully passive in operation and requires no special procedures by the driver to arm or disarm the system. It is invisible to normal scrutiny and is operated by a transponder within the key body. This communicates with the module through a transceiver mounted around the ignition switch lock barrel.
The PATS functionality is incorporated within the powertrain control module.
PATS keys contain an electronic device inside, and are physically larger than a non-PATS key.
The transponder code reading is carried out when the key is inserted into the ignition lock barrel, and turned from position 0' to position II' or III' to crank the engine. If the PCM receives the correct code signal, the engine will start. Should the code received not be recognized, the engine will not crank as the PATS is still armed and the engine immobilized.
Anti-Theft Indicator
Whenever the ignition is switched on the anti-theft indicator will remain on for three seconds while the system carries out an initial ignition key-read.
The anti-theft indicator will flash rapidly for three seconds to indicate the PATS has immobilized the vehicle.
For additional information on the PATS fault codes, refer to the Diagnosis and Testing section.

Look under the dashboard. Most alarm systems have an over ride button. Look for a small micro switch. Press the button while turning the key on.
Hold it while starting.

disconnect the alarm system from under the dash.battery to starter direct will turn the engine over fine but ignition system still runs through your alarm system.It's also a theft prevent system so your car will not be stolen.The alarm went bad preventing your car from starting.That means putting the ignition wiring back to factory.

First to turn off the alarm you simply put the key into the drivers door and turn it to unlock the door twice, this is the factory setting to turn off activated Volkswagen alarm. As for the power locks they are air activated, in the trunk near the latch there should be a small electric motor that drives a small air pump with air lines running to all your locks. If this electric motor as worn out your locks will not operate, simple fix replace the motor. I'd try a used one first from a scrap yard to make sure but always check to see if there is power to the motor (you will need another person with a test light to perform this job). Let me know if this works. Vdubs 4-ever !

You might have a problem with the antitheft system, I don't know what you've done or tested so far. But usually with the alarm enabled there wont be any start at all. It does sound like there is a problem with the ignition switch, but that's only if it starts and stalls after you let the ignition key go. The anti-theft alarm, is this a VTD, factory system, a factory alarm system, or an aftermarket alarm?

Try removing the alarm system relay, some car alarm has also a fuse on the alarm that you can remove.
Many car alarms unlock by inserting and turning car key while you connect the battery.
