What it does, is shut the fuel pump off if the oil pressure drops below a set amount. When you first turn the key to RUN or START, the ECM makes the fuel pump run for 15 or 20 seconds to allow the engine to start. The TBI systems really are simple and easy to work on but you absolutely need to have factory level manuals to work on them. When I was undoing some farm repairs on a S-15 my younger brother had (the fusible links blew and all that nasty electronic stuff *and* the ignition switch got wired around), the fuel injection wiring was pretty straight forward to troubleshoot and fix. There is a lot of wiring but it's all color coded and the GM manuals are very good. The downside, of course, was cost. I had to replace all of the sensors except for the temperature and oil sensors, the ECM, and rebuild the throttle body. The parts bill was about $600. BTW, if anyone is curious about the level of work done to this truck before my brother got it, let me just say that it had fuel hose plumbed into the rear brake line and that was one of the better repairs.
