Basic Fuel System Diagnosis - Ford Ranger Maintaince And Repair Manual

BASIC FUEL SYSTEM DIAGNOSIS

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
the information on engine electrical components and ignition systems found earlier in this manual. If the
ignition system checks out (there is spark), then you must determine if the fuel system is operating properly
(is there fuel?).
