did you varify that the pin timing also shows the correct amount of plunger lift for that pump?

also just want to make sure i got this right. all you done was pulled the pump off so that you could change the tappet cover then you put it all back together correct? didnt do anything else?

Didnt verify just tried to set it back to stockish timing to see if would run. And yes all i did was remove the pump to replace the tappet cover then reinstalled pump

i would think that it has to be the timing then but it sounds like your doing everything right. your not changing directions at any point while your timing it are you? you turn it clockwise till the needle bottoms out then keep turning it until you get to 7mm of lift without ever going backwards?

again it sounds like you got your bases covered on the timing. have you checked the fuel system?
