5.0 HO

I have an HO engine which has a different timing order. does this mean that i have to get a special aftermarket cam?

HO runs a 1-3-7-2-6-5-4-8 firing order.

I have a 94 5.0HO and am trying to get the codes off the OBD I first tried the OBD2 by driver panel and it is showing not connected with key on or off . Found on the Forum it may be OBD! and found behinnd passenger side front strut and is also showing not connected. It is a Autozone Autoxray 2500B and tried with key on and off and says to use yellow OBD2 any ideas what it going on

i meant in terms of the firing order being different than a non HO engine. Like can i buy any aftermarket cam like a b303 or whatever hydraulic roller or do i have to buy one specifically for the HO firing order.
