There are a variety of reasons why a Volvo 740 will not start properly, ranging from electrical to sensors, starter, battery charge, air intake, fuel delivery and ignition sparks. Knowing how to diagnose some of the common causes leading to starting problems can help resolve them more quickly.

Common Problems

Starting problems with a Volvo 740 can be divided into mechanical, electrical and fuel issues. Mechanical problems may include a grinding starter motor or a broken timing belt. Electrical problems may include a voltage drop coming from an old battery or corroded battery terminals. Fuel injection issues may include a myriad of complicated problems or one as simple as replacing the number one fuse, which protects the fuel pump.

Technical Service Bulletins

Websites, such as TSBData, publish technical service bulletins (TSBs) and recall information for several different production years of the Volvo 740. Some TSBs for the 1989 Volvo 740 include adding a protective tube to the battery cable and cold starting problems. Other TSBs include fuel system, rpm sensor, oxygen sensors, the charging voltage of the battery and the fuel injection control unit. Stay up to date on your TSBs to keep your 740 running smoothly.


Many claims for Volvo 740's include difficulty with cold starts. The 740 is equipped with a cold start sensor placed near the thermostat housing that may need cleaning or replacement. Other cold-start or no-start sensors to check can include the manifold absolute pressure, air intake temperature-control sensor or the coolant temperature sensor.
