need more info . spark , fuel ???
No, it doesn't have such a switch.
This is usually caused by a bad seat safety switch.
Not only would the safety switch keep the engine from starting up, the starter would make no attempt to crank the engine over.
Ignition switch
There is no safety switch that can be operated manually . The engine does however have a fuel cutoff switch integrated in to the oil pressure switch/sending unit that shuts off the fuel pump to protect the engine in case of loss of oil pressure.
It prevents engine cranking unless the clutch pedal is pressed.
To kill the engine if the operator is thrown out
There is no inertia fuel pump safety switch in a 1997 Infinity qx4 3.3L 6 cylinder engine.
The Renault Clio Grand 2001 model does come equipped with an engine safety cut off switch. This is a feature that is commonly seen in most newer model vehicles.
The safety neutral switch on a 1989 Nissan Pickup with an automatic transmission and a D-24 engine is located on the transaxle. The neutral switch will be found where the linkage attaches to the transaxle unit.
If you have to wiggle the shift lever in park or neutral to get the starter to crank the engine, the neutral safety switch is probably worn or out of adjustment.
I'd start with the kickstand safety switch.
