preh-see-ZAH. That middle s is a buzzing z, because it sits between two vowels.
This word illustrates the intervocalic-s rule better than it illustrates stress: the c-s at position two stays unvoiced because the c supplies the sound, while the lone s at position three is bracketed by vowels and must buzz. The weight, as it happens, lands on that buzzing syllable.

"Preciso de ajuda" shows the required preposition: "precisar de" is the pattern, and the "de" is a quick "djee." "Ajuda" has a soft "zh" j and an intervocalic d that stays hard, so the phrase runs "preh-SEE-zoo-djee-ah-ZHOO-dah" with three different palatal-ish sounds in a row.
Pronouncing the third syllable with a hiss — "preh-see-SAH" — is the standard error and comes from reading rather than hearing. Intervocalic s is z. The preposition is the other pitfall: "preciso ajuda" without "de" is wrong when the object is a noun, though "preciso ir" with a bare infinitive is correct, which makes the rule feel inconsistent until you notice it's about nouns versus verbs.
