Hi, can you be a little more specific?
5.0 is direct injected, so it misting fuel right in to combustion chamber, not in to the ports before intake valves. Also, what do mean "side exhaust"? Only exhaust pipe outles are at the back of the vehicle. Please describe the situation a little better.

You have to look in one bank.
Complete bank is misfiring.
Not fuel pump, not mafs, not coils not sparks.....
I dont know your engine but i would check injectors and connections and also i know you have a second fuel pump mechanical maybe it is dying.
Check your fuel pressure and look at fuel trims.
If you have +20 long term fuel trim, you have fuel based problem not ignition

Hi. I think it is best if you try to read the codes, if there is any.
These injectors sometimes develope a leak and drip fuel in to combustion chamber.
From friendly LR Tech I heard that ECU will/can shut off a cylinder if it detects misfire or certain issues there.
It is very unlikely that all 4 injectors develope an issue, probably only 1, if you remove spark plugs - the one in problematic cylider will be wet.
What is really really strange - that this all was provoked by replacement of snout. Are you sure you did not damage any wiring etc while at it?
It is hard to make up a relation between these two things.
