Scirocco Register

I have a mark 1 scirocco storm it won’t start got fuel and spark changed fuel pump and filter changed the ignition coil control unit been running for 5 days now won’t start just like before I changed the coil control unit is this just gone or is there something else stopping it starting can anyone help please

It’s really hard to say what could be wrong but start with the simple stuff, how’s the car battery? Try a full charge if you’ve been cranking the engine over lots. Check for a good spark. What do the spark plugs look like after cranking, are the smelling of fuel?
How are the dissy cap, rotor arm, HT leads and spark plugs, are they new?
