I know about those companies but the oil sender feed is worth the extra 
work (GM just T'd two different sending units together in a lot of 
applications). 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.
