Hello,
The motor starts and runs for about 10–15 minutes, then stops and won’t restart. Sometimes it shuts off while idling. Other times, it won’t restart after being turned off. When it fails to restart, it typically won’t start for several hours; then after about 3–4 hours it will restart and run again for another 10–15 minutes.
When it won’t start, the error code displayed is “Emergency Kill Switch.” We’ve checked the switch and even tried jumpering it out, but we have not replaced the switch yet. Is the switch supposed to show a resistance value of approximately 2.0 kΩ when it is not closed? We’re only seeing either an open circuit or a closed circuit (0 Ω). We’ve also seen some switches that read around 2.2 kΩ when not engaged.
When it won’t crank, all voltage measurements read 12.3 VDC at the battery, the engine, inside the engine fuse box, etc. However, the display unit always shows 0.0 volts when it won’t start, as if a 12 VDC circuit is open somewhere.
Hot wire kit tests. When we install the hot wire kit, the Fuel Pump and Ignition relays engage, but the Starter Relay does not. If we jumper out the Starter Relay contacts, the engine will crank.
So, does the hot wire kit bypass the Emergency Kill Switch? Also, what actually triggers the Starter Relay? Does the ECM command the starter relay, or is it activated through a chain of switches/components (e.g., keypad, circuit breakers, interlocks, etc.)?
