2003 Ford F-150 plugs

It would be very hard to misup on the firing order.I was very care full with the work but we all mess up.I did go over 3 time and even pull each cole out and put them back. If I take of the fule line would that cause any thing. It sounds like it just not firing on some of the plugs.I could see if the coles had some were to them but nothing I could see. Isent thier some codes to tell me whats up.I found that if I start the truck what the trip button in I get some code but I dont know what thay mean

The plugs as you know are new. It did run good before
all hose are ok
all connection look ok
i also check if the harness is making contack
the plugs are double platinum
app764 autolite gap at 55
the old ones were gap much more.I was thinking if the plug harness mit slide along the plug.I had to remove the fule lines to get the plugs out. It seems like its not firing on all plugs but I check them please help
