MY CAR READS A ENGINE IMMOBILIZER FAULT AND WONT START

if the alternator is not charging , there will be a red battery light on the dash
reasons for engine stopping are
broken timing belt/chain, cam/crank position sensor failure
immobilizer activation
ignition control module failure
run the fault codes as some engine lights only light up for urgent problems that require you to stop the engine

run the fault codes
reasons for not starting are
broken timing belt /chain
cam/crank position sensors wot working
immobilizer inoperative
problem ignition control module
failed coil/s ECM fault
no fuel pressure ---faulty pressure regulator
faulty pump
gear not in neutral or park

That fault will cause a no start, it senses an unauthorized person is trying to start eh car. You need a shop to scan the system control module and see what is causing the fault.

Economy mode means you should charge your battery firs as it might be almost flat.

It could be an Immobilizer fault, if the spanner /car light comes on.
If you have a spare key, try it
A Flashing spanner light normally means immobiliser fault hence the non-start. The spanner light left might just be an indication that it has stored the "wrong transponder" code.
Opel will have to clear this but you might need a CIM as well that is the bit that reads the key to allow it to start.
Try the spare key if you have one

On 1.7 DTi models, a defective solenoid in the pump can cause failure of the ECU due to excessive current draw causing components to burn out. but this *should* cause other fault codes to appear.





.

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

You have an electronic immobilizer key recognition problem. Now your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel.

Everytime when you had a new key you must programm all available ignition car keys before trying to start the engine with this new key !!!



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.

Dear Madam or Sir,

this is a well known problem with the immobilizer system.

See the following official tech bulletin :

Affected vehicles:
All models with Bosch RB8 instrument panel up to 2002 MY.


Problem:

Engine starts and cuts out immediately.

Trouble code stored: 17978 (P1570) - engine control module (ECM), immobilizer active.

Trouble code stored: 18058 (P1650) - CAN data bus, instrumentation - no signal.


Cause
Immobilizer fault.
System arms when ignition switched ON.

Remedy:
Access fault memory. If trouble codes present fit modified instrument panel (incorporating immobilizer control module).

Note: Immobilizer can only be programmed using diagnostic equipment.

If you have wellow lamp with key appears on a dashboard that means your immobilizer is ON and there is problem to start the engine.But only way to reprogram the immobilizer is with diagnostic equipment.Did you change the dashboard? The same problem happening

Try 2nd key.

If it does not fire up then it's the immobilizer / alarm circuit at work or at fault.
