Hi,

Are you changing the parts for second hand ones,    have you had any electrical tests done on the Battery and alternator ?

No new Battery then I had a new alternator which I then swapped for a new Lucas one trying to get to a auto electrician in the morning only started after I had new coils fitted whatever thanks oldcodger.

Just to add the exterior lights , radio etc work fine and once the car has been left it will start first time so it can t be the alternator or Battery thanks oldcodger.

Hmmm, perhaps try all earths for good contacts, then all fuses for good contacts too

It my help to state your exact car details- so what year, engine, gearbox ......

Have you checked the IAC valve? That can get clogged, its attached to the bottom of the throttle body.
