Check out your lower timing wheel (sprocket) at the end ot your crankshaft. If the wheel has some moove to left and right on the crankshaft, you should change the timing wheel. But, first of all, check the gap between the pulley and the crankshaft position sensor. (it should be ~0,4mm)

I can't tell what 2 pins you put the jumper wire into. can you just reply comment and explain where on the port you put the jumper wire in please. ty

code 12 is the beggining/end of the reading. Code 12 is not a fault code!

I've got an opel astra 2000, what pins should I jump? Where can i find the fault code?

what is the engine code? For example C14NZ (means 1400ccm and central injection)

How can you read the trouble codes from your Opel Corsa B C14SE? 1)get a piece of wire 2) Ensure ignition switched off 3) short terminals in the DLC 4) turn ignition on 5) After a short flash, you will read probably trouble code 12. This is the beginning/end of the reading. All of error codes repeated 3 times.

or right my mates corsa 1.2 n reg ...it wont start and the engine light keeps flashing and its only code 12 thats there?

This system can't recognise if no petrol pressure, or no ignition. Check the general parts.

i no coment 11month old, but flashing when trying to start is the immob
