Hi there. From the description you have provided, it would appear you have replaced everything related to the vehicle’s engine running. Obviously, replacing components without a diagnoses is not working.

It could be, a faulty ignition switch allowing the engine to start, then dies in the run position. Also, it could be a faulty electrical component that you have already replaced.

Tests need to be performed to confirm the diagnoses, before spending any more money replacing parts. I recommend having your vehicle’s starting issue diagnosed and repaired by a certified technician, such as one from YourMechanic.
