I need the firing order of a 2004 Ford F150 5.4, 3 valve. I have to remove coil pack e.

USA car> RTM its in the manual
PCM dictates firing order this is a fact and any cam chains.
no job told at all, why? doing this.,
pulled the coil pack and not do HV wire 1by1.? oops. thart?
V8 , has 8 COPS THEN, and harness wires and CPM dictate order
so you doing ACTS with the CAM?not told the job or act.
#1 is ,the bank that is most forward bank of al V engines.
so we all know just at a glance where is #1
now banks
order
1 - 3 - 7 - 2 - 6 - 5 - 4 - 8
right front is #1 (drivers seat perspective)
even odd banks.R 1234, L=5678
2nd google finds this.

Firing order is 1342 --- Order on the Coil Pack is 4,1,2,3 -- Line the plug wires up in that order starting at one end of the coil pack, if that doesn't work, start at the other end of the coil pack with the same 4,1,2,3 order. Cyl. #1 on the engine is closest to the crankshaft pulley (and all other pulleys) -- Disregard the firing order at this point, it will only add to the confusion. Stick to the 4,1,2,3 order for lining up the plug wires

STANDING FRONT OF VECHICLE CYLINDERS FACING YOU ARE 4 5 6 AND BACK CYLINDERS IS 1 2 3 NOW ON PIECE PAPER LOOKING AT IGNITION COIL PACK FACING YOU WRITE BACK NUMBERS 123 AND UNDER THAT NUMBER 1 2 3 WRITE FRONT NUMBERS 5 6 4 THATS YOUR COIL PACK PLUG WIRES LOCATION. LIKE I SAY 5 6 4 IS PLUGS WIRES LOCATION FACING YOU AND BACK NUMBERS 1 2 3 PLUG WIRES LOCATION ON COIL PACK. FIRING ORDER IS 1 4 2 5 3 6

1 is right front, but coil pack should be marked with cylinder numbers as below. Firing order is 1-4-2-5-3-6. OK?

No order, just do one at a time. on the engine there will be a valve cover on each side of the engine, below is a valve cover, the arrows are pointing to is the ignition coil packs, coil packs might have a plastic cover over them, if so remove cover, disconnect harness from coil, remove small bolt holding coil pack, pull up on coil, remove spark plug, do the same on other side of engine, don't forget to check spark plug gap, the spark plug gap is .050", hope this was very helpful.
