1990 S2 Hot Start Issues

[MartinBrown2409]

Hi, there are various mentions of hot start issues when I search mainly it seems with Chimaera’s. Recently bouught a S2, it hasn’t been used much in the past 5 years so I’m giving it some tlc during the winter months. It starts absolutely fine when cold, I’ve noticed a bit of lag when revving from the EFI but this disappears after a few minutes as car gets warmer. But then it just will not start for at least 30 minutes until it’s cooled down.
Has anyone any new advice on how to fix this ? Car does have a thatcham immobiliser fitted but you can hear the fuel pump whirring.
Thanks
Martin

Hi Rob, it turns over fine just won’t fire. After a few minutes of trying then battery goes fiat and then just clicks. After it’s cooled down then it’s fine and although battery hasn’t got a lot of charge it will start straight away when cold

Thank you, that gives me something to certainly start with. Will let you know how I get on. Many thanks.

Quick update. Replaced the oil filled coil with new Lucas DLB 125. This seems to have done the trick with hot start and the lag from EFI has gone as well. Thanks for the advice
