My car was feeling sluggish so I turned it of and it wouldn't tart back up it would turn n tried furring but now the firing has stoped I changed coil pack on 1998 vaxhall Astra petrol any advice? It has an imoboliser as well dunno if this helps a friend said it might be that.
We have no info on these cars, but scan for codes and check fuel pressure first. If this has anti theft yo migh ttry resetting it, this may be like a u.S. Gm car and turn key on for up to 10 minutes until theft light goes out then turn key off and try to start car. But it wil probably be covered in your handbook if you have one. If this has a diode type key try another key if you have one.
