Refer to the following list for possible causes: – F8 fuse – Battery or connections (refer to CHARGING SYSTEM) – D2 diode – Start button – Engine stop switch – Starter solenoid – Clutch engagement switch (SM6 model) – Gear position sensor (SM6 model) – D.E.S.S. – Brake light switch (SE6 model) if transmission in gear) – Electrical cables/connections – ECM. If fuse F8 continuously blows, isolate the following components to determine the source of the short circuit: – Pre-starting relay – Starter solenoid – Heated oxygen sensors – EVAP purge valve – Fuel pump – D2 diode – Clutch solenoid valve (SM6 model) – Camshaft position sensor – Reverse actuator relay (R1). On SM6 model: – If starter cranks only with the clutch lever depressed, verify the GBPS (gearbox position sensor) and its circuits. Refer to GEARBOXsubsection. – If starter cranks only in neutral, carry out the CLUTCH SWITCH CONTINUITY TEST
