SOS misfire/won’t start/electrical

[adam24r]

Hello, stupid college kid here tryna figure out a Jeep...

so I had a cylinder misfire/fuel injector 1 error code that seemed to start directly after parking in reverse on my slanted driveway

Replaced the injector... worked for about a day then the error and misfiring came back

had the computer checked and it was good

would still start but misfire until today and now it won’t start... I’ve had the battery and alternator checked recently

I see THIS loose wire pictured belies that I think might be the problem but I also can’t figure out where it goes

thank u in advanced for your wisdom Jeep dudes

That's probably for the under hood light

Plugs were done when and brand?

Coil condition?

Fuel pressure is?

Yeah plugs/wires/coil and fuses are a good start. What are you getting when you attempt crank? Have you tried allowing the Jeep to prime before crank? I assume you're still getting dash power and it's trying to turn over.
