hello, would like the following question: would like to add volvo 740 kombi as a winter car (bj ca. 91, get it given) ! now there is a problem: when starting the engine turns, but it doesn’t start!!!! you don’t hear a petrol pump! I know the fz already some years and the error occurs opener, that is, sometimes he likes, then again not!!! does someone have a concrete idea what it might be about?
