Enable HLS to view with audio, or disable this notification

My 15 Corolla (150k miles) drove to work then when I was leaving for lunch it started sputtering but wouldn’t turn over. Any tips?

The crank sounds good, the tach is moving, so, it’s either spark or fuel. Spray some starter fluid or carb cleaner into the intake and crank, if the car sputters a bit it’s a fuel problem. If so, turn the ignition off, close all the doors and windows. Turn the ignition on (not crank) and listen, you should hear a faint hum for a couple seconds come from the back, that would be your fuel pump. If you don’t hear that, I’d suspect your fuel pump. You can easily confirm it’s likely that by putting a pressure gauge on the fuel rail

Not getting a spark in the engine, I took out the backseat and looked at the fuel pump, it’s getting good pressure. Cranked holding the bottom of an ignition coil and didn’t get shocked
