2016 3.5 ecoboost ignition coil / cylinder map? Error codes

[Ranger519v]

I've searched the web and this forum but can't seem to find a cylinder map. I got error codes P0304 and P0305 so I need to replace 1 or both ignition coils for cylinders 4 and 5. Can anyone point me to a map?

After further research, when standing in front of the car and facing the engine, I believe it is 1 - 2 - 3 left-to-right across the back and 4 - 5 - 6 left-to-right across the front. If I have it wrong, someone will correct me.

Please help diagnose these error codes​

Was happily driving down the freeway when I suddenly lost about 25% power and the engine light came on. Horrible idle and struggles to get off the line. Limped into Autozone to use their diagnostic reader which showed the following:

P0304 Cylinder 4 Misfire Detected
P0087 Fuel Rail/System Pressure - Too Low
P0300 Random Misfire Detected
P0305 Cylinder 5 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P0087 Fuel Rail/System Pressure - Too Low
P0300 Random Misfire Detected
P0305 Cylinder 5 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P0087 Fuel Rail/System Pressure - Too Low
P0300 Random Misfire Detected
P0305 Cylinder 5 Misfire Detected

I purchased 2 ignition coils and 6 spark plugs. I changed the coils and plugs in cylinders 4 and 5 and though I've not returned to AutoZone to read any updated codes, it is still running horribly, engine light on, and drinking gas! I was told there is no fuel filter to change? I'm worried about P0087. Anyone out there have any experience on what I can try before having to spend $$$'s at the service center?

Thanks in advance,

Bob

Sounds like bad injectors to me. If that doesn’t solve it I would bet it’s the high pressure fuel pump.
