My car has an automatic transmission.

Hi there. Proper diagnoses needs to be performed for the no start condition. Circuit tests should be done, to determine whether there is a loss of spark, loss of fuel, or a loss of both. Assuming the engine turns over normally, it could be, a faulty ASD (automatic shutdown) relay, a faulty fuel pump relay, a faulty fuel pump, a poor connection or electrical fault in the power distribution center. I recommend having your vehicle’s cranks but won’t start diagnosed and repaired by a certified technician, such as one from YourMechanic.
