Have any idea what to expect next for a 98 gmc jimmy?

In 5 years I've only had to replace a heater core (which still doesn't work) and a water pump... Now it looks like an electrical problem. These things are usually common among the whole group of owners. So what problems might I need to look out for, in your experience?

EGR Valve, Fuel Injectors, Fuel Pump, Radiator leaks, Intake Gasket Leaks. All are fairly common on the 4.3L engine found in the jimmy/blazer.
