Modal Verbs in the Past
vouloir, pouvoir, and devoir change their flavor of meaning depending on which past tense you put them in — the imparfait describes an ongoing state, while the passé composé often marks a single decisive moment, sometimes with a surprisingly different English translation.

Irregular past participles: voulu, pu, dû
j'ai voulu, j'ai pu, j'ai dû
I wanted, I was able to, I had to
All three modal verbs have irregular past participles that must be memorized: vouloir → voulu, pouvoir → pu, devoir → dû. Note the circumflex on dû (masculine singular only) — it distinguishes the participle from du, the partitive/contracted article, and disappears in the feminine and plural forms (due, dus, dues).
Imparfait = ongoing state, passé composé = a single moment
Je voulais partir. (I wanted to leave — ongoing desire) vs. J'ai voulu partir. (I decided/tried to leave — a specific moment)
I wanted to leave (ongoing desire) vs. I decided/tried to leave (a specific moment)
Because vouloir, pouvoir, and devoir describe mental/internal states, the choice between imparfait and passé composé shifts the meaning more noticeably than with action verbs. The imparfait describes a state that was simply true at the time; the passé composé marks the moment the state resolved into an action — often best translated with a different English verb entirely. English has no matching tense-pair to lean on here, since 'I wanted' covers both readings and only context disambiguates — French forces you to pick a lane.
The negative flips the meaning further
je ne voulais pas (I didn't want to) vs. je n'ai pas voulu (I refused)
I didn't want to vs. I refused
In the negative, the passé composé of vouloir and pouvoir often reads as a stronger, more decisive English verb: je n'ai pas voulu = 'I refused' (not just 'I didn't want to'), and je n'ai pas pu = 'I couldn't / I failed to' (a specific failed attempt, not a general inability).
