Ok what is weird is that when I line the dots up dot to do with the dot on the crank gear pointing up and the dot on the cam gear pointing down the rotor button faces the firewall and points to driver side like towards the steering wheel. It should be facing to the front but pointed towards the drivers side head light. Im beginning to think there isnt even anything wrong with the timing set as I watched a video on you tube were a guy was changing the timing cover gasket and he checked his chain and mine was tighter looking than his was and he said his was good and tight. My truck all of the sudden started stumbling and cutting out while driving down the road and I have changed everything I can think to change. It will barely idle when cold, Warms up it idles decent you can drive it down the road and its fine till you get up to 45 mph at which point it makes a little stumble then cuts out completely and if you hold the gas down will jerk back and fourth and buck. Ive changed ignition module, cap, rotor, wires, ballast resistor ,coil, distributor and carb. It has made no change at all.
