Stopped running on highway, no smoke, no high temperature reading showed on gauge. All just went out. Radiator leak, towed. How to check what sensor to start again?

Good evening.

Some possibilities.

1. Battery low voltage. You need 12.6 volts at the battery for all accessories to turn on. Charging rate when running should be 14 to 14.5 volts.

2. Fuel delivery issue. Low or no fuel pressure could be the reason. Can you hear the fuel pump run?

3. No spark from possible bad crank sensor. When you crank the engine does the tachometer move up a little? That will tell us if the sensor is sending a signal.

4. Compression. The engine needs compression in order to run.
