Big trouble!

I sputtered into a parking lot after I started running rough with cel flashing. Pulled low fuel pressure bank one code and misfire cylinder 1 and 2.
Currently waiting on tow truck. Any rough ideas?

Sounds like a stuck open injector to me. Same symptoms I had. Sounded like a boxer motor.

Thanks for the response Jordan.
That was my fear but the multiple cylinder misfires and low pressure code gave me hope it wasn’t. Then, I remembered fuel pump relay. Bingo! Swapped it out, hard start and ran rough for a couple seconds then smoothed out. Drove home normal, no codes and registered no misfires. I think I’m good.

Tow guy came with a regular truck and I was like I’m AWD bro. Oh, I’ll get the other guy. I said never mind. Got a ride to advance with fingers crossed the relay was the fix.

It was very boxer/cam’y sounding. I kinda liked it. Ha!

Nice! Glad you have it worked out for now, I hope that’s all it needed. I once called a tow truck before and by the time he came I didn’t need him....he tried to get payment for showing up....I laughed. He drove off empty handed.

Yeah once I calmed down after picturing ripping the heads off my motor I was able to think clearly. Off the top of my head I imagined my brother-in-law‘s 3.5 f150 ecoboost that had similar symptoms. We thought injector. Changed it only to realize after that didn’t fix it he only had about half of his Bank 1 exhaust valve left. Not great for compression.

Good stuff!
