Pursuing works of the law in contrast to faith means
the Jews thought they could become perfect by maintaining the law of Moses; or
the Jews emphasized circumcision and dietary laws instead of faith.
Paul is saying that Israel pursued their relationship with God as though it were based on upholding each aspect of the Mosaic law. The problem is that the purpose of the law was to reveal sin, not lead to righteousness, so Israel could never establish their relationship with God through works of the law. Rather, the only way to a right relationship with God is by faith.
We can detect this is Paul’s meaning because his main message in Romans 9:1–33 is that righteousness is not based on national identity or human exertion, but on God who has mercy. Further, we know from Romans 3:9–20 that all are under sin, and no one will be justified by works of the law, for through the law comes knowledge of sin. In other words, because of sin, no one can make themselves right with God through human effort. Rather, one is right with God by his own mercy through faith.
Some contend that when Paul refers to works of the law, he has in mind specifically Jewish identity markers such as circumcision, dietary restrictions, and Sabbath laws. The idea is that Israel considered these to be the works of the law, but they ignored the fact that the Gentiles are included through faith.
The problem with this view is that Paul uses the term works
to refer to the works of the law. The term covers not only Jewish identity markers such as circumcision, dietary restrictions, and Sabbath laws, but also all aspects of the Mosaic law. Further, we know from Romans 10:5 that according to Moses, the one who is righteous by the law must do the commands, implying all of the commands. So the problem is not with promoting distinctively Jewish aspects of the law such as circumcision and Sabbath laws, but thinking one can uphold the whole Mosaic law.
Thus, when Paul contrasts the works of the law with faith, he has in mind pursuing the Mosaic law in order to be righteous.
Interpretation 1:
The Jews thought they could become perfect by maintaining the law of Moses.
Summary:
The Jews believed that with enough effort, they could keep the precepts of the Mosaic law. And by keeping the precepts of the Mosaic law, they would be righteous before God. Unfortunately, because of sin the Jews could not keep the Mosaic law, which was meant to lead them to faith.
Sin prevents us from becoming righteous. That is, we cannot be in a right relationship with God through our own effort. The only way for us to become right with God is by God’s offer for grace in Jesus Christ, which we accept by faith.

Minor differences:
Our authors agree that the contrast between works of the law and faith is a contrast between keeping the Mosaic law perfectly in order to be righteous and simply having faith in Christ. Since one is sinful, one cannot keep the Mosaic law perfectly, which is what the Mosaic law itself was meant to teach.
Frank Thielman works out this view in detail. He argues that Paul’s point here is that the Israelites mistakenly believed that they could keep the precepts of the Mosaic law, and by doing so they would be righteous. Unfortunately, human sin prevents one from keeping the law perfectly, and the Israelites should have recognized this. Thielman contends that Jews misunderstood the purpose of the law. The law was never meant to produce righteousness, but to provoke faith, which would lead to life.
Thomas Schreiner seems to generally agree with Thielman, but he is less specific. He suggests that Paul’s point is that Israel viewed the law from a legalistic perspective. Thus, those Jews who reject the gospel did so because they believed they could secure their own righteousness by the law, rather than by faith in Christ.1
