I just swapped out a 2.8 and put in a 4.3 TBI out of a 1990 Jimmy. I used the wiring harness for the 4.3. there are two plug in connectors in the S15 i put the 4.3 in that don't match the computer from the jimmy. Could this cause the injectors for the TBI to not inject? I have good pressure and flow of fuel but no injection??? can anyone help......

The ECM for the 2.8 liter engine will not run the engine on the 4.3 liter. The programs are different to run the different engine. Get a ECM for the 4.3 from the Salvage Yard to get your engine running.
