ARE YOU SOMEWHAT MECHANICAL?

ARE YOU ABLE TO REMOVE SPARK PLUGS AND PUT 'EM BACK?

HAVE YOU TAKEN THE DISTRIBUTOR OUT. HIDING INFO, MAKES IT HARDER TO ASSIST YOU!

SORTA. WHAT EXACTLY HAVE YOU OR THE "OTHER ONES" DONE TO GET YOU TO THIS POINT?

KNOWING SOME (ALL) OF THIS MIGHT GIVE ME A STARTING POINT

Yeah I took it out but forgot to remember the firing order how would I be able to fix it? Also I might have arranged the spark plug wires wrong and don't know the order it was me first time trying it.

IF YOU TOOK IT OUT......AND DID NOT STICK IT BACK IN 100% EXACTLY HOW IT CAME OUT (EZ TO GET IT WRONG)......YOU WILL NEED TO LISTEN TO THE DIFFERENT WAYS OF REPLACING IT RIGHT

I'M SENDING "DAVID AND CHAD" TO GIVE YOU A HAND

WATCH THESE A FEW TIMES, THEY ARE VERY HELPFUL

I THINK I GRABBED YOU THE CORRECT DIAGRAM AT THE BOTTOM

REMEMBER # ONE's POSITION ON THE DISTRIBUTOR CAP MAY VARY DEPENDING ON HOW YOU INSTALL THE DISTRIBUTOR

WHEREVER #1 WINDS UP---THAT IS THE STARTING POINT FOR THE SEQUENCE

LISTEN TO DAVID AND CHAD SEVERAL TIMES BEFORE YOU ACT!

KEEP ME POSTED

YOU MEAN THE ENTIRE WIRE FROM BEGINNING TO END, GOT SWAPPED FROM #6 TO # 3BUT IS STILL HOOKED UP CORRECTLY IN FIRING ORDER?
