There is no cam or crankshaft sensor on that one. The spark should be white in color, not orange. Check the spark from out of the coil wire. Orange color is a weak spark. Check the cap and rotor, make sure the spark plug wires are in decent shape. Did this run after the timing chain was put in? Try a little gas down the throttle body to see if it wants to fire. And if the throttle body has not ben off the intake, check the base gasket, it may be shot.
