hay man i need all the info i can get--but the thing is my truck has ran fine untill a week ago--like i said when i first had this problem i pulled the cap and saw that the cap was chipped/burned ware the carbon brush goes though the bottom so i replaced it-- that was the only phyisical problem i could find--i test drove it--it ran pretty good for a total of about 1 hour off and on (running around town) then it started doing the same thing as before...

i have been running this same engine set up sence 2004 (besides basic maitnece,

i really think my timimg is shot to H3LL because my dizzy is not even parallel like it has been sence i had shop put it in (the 3 wire plug is at almost a 45D angle facing the cab

and my plug wires are custom cut to fit when its sitting parallel
the truck wont think about starting when i set it parallel
