Fuel Pump: Testing and Inspection

SYMPTOMS
An inoperative fuel pump will cause a "no start" condition. A fuel pump which does not provide enough pressure can result in poor performance.
An inoperative fuel pump relay can result in long cranking times, particularly if the engine is cold. The oil pressure switch will turn "ON" the fuel pump, as soon as oil pressure reaches about 28 kPa (4 psi).

Refer to Computers and Controls / System Diagnosis / Chart A-3 for diagnosis of the fuel pump. Testing and Inspection
