started my car for the first time today after putting in the engine, it starts ok and will rev ok but it just wont idle it dies, now i know that my ht leads are ok and in correc6t order and im getting a spark so im thinking it might be a fuel problem, the fuel pump near the tank is making a horrible whineing noise is this a problem? it`s a new pump tho, there is petrol getting to the correct places as the car runs when i rev it !!! any ideas ?
