You should check to see if your vehicle has jumped timing. Have a mechanic verify that the camshaft timing did not jump after scanning and looking at the crankshaft sensor data to verify it is giving a signal. If it is giving a signal, then the cam and crank signals are way off and causing the wrong ignition timing. If you need to have a local expert come check this problem for you, a certified technician from YourMechanic can come to your car's location to diagnose the hard starting issue and pinpoint the correct fix.
