To find the constants p and q, we can use polynomial long division.

Divide x³ - px + q by x² - 3x + 2:

_______________________
x² - 3x + 2 | x³ + 0x² - px + q
- (x³ - 3x² + 2x)
_______________________
3x² - (p - 3)x + q

The remainder is 3x² - (p - 3)x + q.

We are given that the remainder is 4x - 1. Therefore, we can equate the corresponding coefficients:

3x² - (p - 3)x + q = 4x - 1

Comparing the coefficients of like terms, we get:

3 = 0 (coefficient of x²)
-(p - 3) = 4 (coefficient of x)
q = -1 (constant term)

From the first equation, we see that 3 = 0, which is not possible. Therefore, there are no constants p and q that satisfy the given conditions.
