Is it timing or something else

Check ur spark plug wires to make sure u have the right firing order

I did already i even put the old spark plugs and wire to see if that was the problem i double check the gap and they are fine and on the firing order i have the speks of it. I dont know what wlse to do

If the timing is right, sparkplugs and wiring then chec to see if U might've accidentally disconnected a sensor plug or vacuum hose

I did check all that and i have spark on cilynder 1 i made my timing gun work allready but now everytime i step into gas pedal check engine light flashes but truck doest shake no more. All this is on a park mode i havent switch gear on it

I think i found the issue my cousing tied the distributor cab to hard and the screw from the inside was loose. Thanx cousin for adding more bills lol
