BASIC FUEL SYSTEM DIAGNOSIS

Imprimir

When there is a problem starting or driving a vehicle, two of the most important checks involve the ignition and the fuel systems. The questions most mechanics attempt to answer first, "is there spark-'' and "is there fuel-'' will often lead to solving most basic problems. For ignition system diagnosis and testing, please refer to Engine Electrical of this guide. If the ignition system checks out (there is spark), then you must determine if fuel system is operating properly (is there fuel-).
