As at the previous race in Brazil, the Brabhams were easily the fastest cars in the Friday morning session. Stefano Modena was quickest on this occasion, with Martin Brundle in second. Alex Caffi pre-qualified his Dallara in third, with Nicola Larini's Osella in fourth. Only four cars went through from this session now that the injured Streiff had been replaced at AGS by Tarquini, who had left the abortive FIRST team.

Onyx improved on their showing in Brazil, with Bertrand Gachot just missing out on pre-qualification in fifth place. The EuroBrun of Gregor Foitek was sixth, ahead of the second Osella of Piercarlo Ghinzani. The other Onyx of Stefan Johansson was eighth, followed by the second AGS of Joachim Winkelhock. Tenth was the Coloni of Pierre-Henri Raphanel, just ahead of the two Zakspeeds of Aguri Suzuki and Bernd Schneider, the Japanese driver outpacing his more experienced team-mate. Nearly four seconds adrift at the bottom of the time sheets was the Rial of Volker Weidler, despite the German trying all three of the team's cars.^[2]

The only change to the entry list for the San Marino Grand Prix was the arrival of Gabriele Tarquini in the second car of the small AGS team, which had only run one car in Brazil after Philippe Streiff had suffered career ending injuries in pre-season testing. A record 39 cars were entered for the Grand Prix,^{[citation needed]} although only 26 were allowed to start the race.

After their defeat in Brazil, McLaren spent eight days testing at Imola prior to the San Marino Grand Prix. According to Ayrton Senna, they tested everything on the McLaren MP4/5, including aerodynamics, suspension, brakes and fuel consumption. It worked for Senna and Alain Prost, as they locked out the front row and were over 1.5 seconds faster than the Ferrari of Nigel Mansell. Riccardo Patrese showed his and Williams' revival with fourth on the grid followed by Gerhard Berger (Ferrari) with Thierry Boutsen rounding out the top six.

At Tyrrell, Michele Alboreto failed to qualify for a race for the first time since the 1981 German Grand Prix, in the new Tyrrell 018. Only one 018 was available, and although teammate Jonathan Palmer managed to sneak onto the grid in 25th in the older model 017, he raced the 018.
