It's hard to tell from the pic the distance from the timing tape & reader, If it's about the thickness of a dime should be ok . Anything larger that an 1/8" and you'll have the same type of problem.
Did you put the battery back in? and is it good? Changing features and having them stick requires a good battery.
Also try a Feature rest Menu/advanced /reset engine/ Feature reset.
Re-seat the plug that the center rail. chassis ground and tack reader plug into the main board
Clean Tack reader if possible (Q Tip or something thinner)
I can't see anything out of the ordinary on the pics. No strays strands of motor lead wire touching the motor casing ??
