There was a progression of LH jetronic models from LH 2.2 to LH 2.4, and the earlier ones had 4 main injectors and a fifth cold-start injector on the underside of the inlet manifold. On later models the 5th injector was dropped, and cold-start enrichment came from all four injectors.
Mine's a 1991 LH 2.4 with 5 injectors. It's explained in Haynes, and Brickboard has a lot of threads on the subject of variations even with LH 2.4 models.
My understanding is that regardless of which injectors do the enriching, all are triggered by the temperature sensor in the block under no. 3 inlet port, which surely is the first thing to test?
