i just got a 99 4.0 ranger and changed both head gaskets....the heads were pressure checked and were deemed ok. this truck did not run when I got it.
Now it is very hard starting, the idle is terrible and it is backfiring. the left side plugs are very sooty the right ones look better but still dark. The guy had it partialy apart so.... I have a ground strap that hooks to the left cylinder head but don't know where the other end grounds too. I have no CEL at this point. I almost thought of a timing chain the way it starts ????
