A hard-to-push brake pedal coupled with a car that won't start often indicates a problem with the brake booster or a significant vacuum leak. Check if the vacuum hose connected to the brake booster is loose or damaged. If the hose is intact, the brake booster might be faulty and require replacement. In both scenarios, addressing the vacuum system should resolve the issue.
