Purchased in June 2019 (private sale). Previous owner had it for 10 years. Carfax and vehicle itself was clean. I am the 3rd owner. Typical middle-aged owners prior to my purchase. Vehicle currently has only 122k miles, of which I put on 16k. I have had zero issues up until this morning. The most recent activity where the hood was lifted included jumping a relative's 2000-ish Nissan Maxima on March 13 and topping off the engine oil (which is a bi-weekly chore) on March 17. Normal driving conditions/roads over the last month or so. No sudden movements/swerving or hard braking in that time as well. When I turn the vehicle ON, the initialization is normal as only the Battery and Check Engine lights remain illuminated prior to turning over. I let the vehicle sit for about an hour between each attempt to start. It "glugs" for only a second or less to try to get running but dies out. Any help is appreciated. Thank you.
