need more information,what engine,,,there are 6. Have you checked fuses? F2=80a F30=15a F21=20a K4=starter relay.

You don’t disconnect ABS unit.
So CAN Line will be interrupted.
Car don’t start absolutely!

you have some immo unit (ECM,CIM,IPC) don’t active.

Global diagnosis please.

[Ionutzllz]

i have global diagnosis and opcom say no fault codes. i remove cim and i resolder all pins. i enter in measuring block and say key status ok...programmed, crank allowed but when i rotate key no crank. and car with key is blinking. odd

the car...opel astra h 2009 1.7cdti z17dtj 81kw. i remeove the headlight and positive cable from battery. after that car start 3 second then stop and car with key blinking

[Ionutzllz]

if you want i can put some pictures with status of car. i don`t know how to do immo off maybe will start

[Ionutzllz]

error from steering angle is beacause i have not put weel back in cim

Headlight has nothing to do with the ignition/cranking circuit.

Check and replace the antenna (coil) in the key fob:

Can you diagnose all modules? Are they with "no errors"?

[Ionutzllz]

Can you diagnose all modules? Are they with "no errors"?

all have no errors. thats is strange. it is possible to be CIM?

[maucontacto]

all have no errors. thats is strange

Replace transponder

[Kic]

Transponder could be faulty as maucontacto mentioned but also CIM, pickup coil or wiring.
Start with the basic: connectors, fuses and do a continuity check with multimeter.
