There can be a sensor or electronic control unit (ecu) issue. If for example, the crankshaft sensor is faulty, the ecu may not see engine revolution when you’re cranking. If either due to a faulty crank sensor, or ecu, the crank sensor signal is not being read, the ignition and fuel pump systems will not power up. Also, a faulty ignition module can create the same issue. Check for signals from the crank sensor and other sensors. If you still have the issue, then have a certified technician look into the no start condition to find the exact cause.
