hey guys im new to the whole import car scene but i am a very good mechanic. my freind has just bought an alpha romeo which doesent run he was told by the guy he bought it from it needed a new computer. we have replaced the computer and the key as well everything works but the engine will not run on its own. ie need gas or either sprayed into intake. has new fuel pump filter and pressure regulator. i have checked and we have fuel all the way up to the rail. i was thinking that there might be some kinda cut off switch or some kinda saftey thing stopping the injectors from working anyone have any ideas?
