You may have contaminated and clogged the fuel injectors. You can try and clean the injectors if you can get it started, or you may need to replace the injectors if you cannot get it to start. Make sure the fuel pressure is checked to make sure you are getting good fuel pressures. If you want to have this looked at, a technician from YourMechanic can come to your car’s location to diagnose the starting issue, pinpoint the faulty component, and make the correct repairs.
