Car won't start

[Larks]

I have a vauxhall corsa d 08, the car just stoped workin the lights etc come on but it doesn't start, I had it checked and the tech 2 wouldn't read the ecu, I was told I need a new ecu, so I brought a full kit ecu and the car still doesn't work, and the tech 2 still doesn't read the ecu, can any one help please

What lights comes on on dash?
What ecus you changed? list them all as it can help narrowing down faults.

have you checked good earth and good supply to ecu? also check can lines to ecu as well?

Hello, the lights on the dash come on apart from the coil light but a car with a spanned though it comes on, but my first ecu wouldn't read tech 2 so I was told I need a new ecu so I brought the full kit bcm clocks etc, and still doesn't work!? What earth wires? And can lines? Thank u

The ecu I changed was the one under the windscreen

Have you reset and programed it to the car.

So you changed only one ecu under windscreen I believe it was engine ecu
If you ordered ecu kit you should have engine ecu, bcm, cim, ipc, uec
Your problem can be in one of these ecus especially in cim
Try swapping all remaining ecus and try again
If you just changed one without programming you wont be able to start car due to immo mismatch
