No they don't intersect.
The reason is that, an electric field line shows the direction in which a positive charge would move if it were placed at a particular point in the line. (This direction is given by the tangent to the line.)
So, if field lines could intersect, it would mean that when a positive charge is arrives at "the point of intersection", "it would not know which way to go" or it would come to rest.
This is not the case.
On the other hand, field lines can combine
For example field lines radiate outwardly form a positive charge into a negative charge.
