if you read my other post my sapphire is a wierd starter. some times it goes first time you turn it over then it can take ages for it to start. so i tried a p8 in it and it starts fine first go every time but boosts wierd so i put another l8 in that we had and it does the same thing as the other l8. runs fine when it runs but takes an age to start sometimes. is it just the l8 ecus that do this or is it a fuel pump prob or something??? help please
