Question about 1999 GMC Jimmy
If there is no spark and no fuel I'd look at the crank angle sensor. This detects the motor position and the ecu fires the plugs and injectors respectivly. Is there fuel pressure at the injector rail or no fuel at all?

try the oil pressure switch, that was a common problem on Gm trucks when I used to work on them, the oils switch was bad and woulden't allow it to start and the ones I worked on were on the back of the distributor.

SOURCE: 1995 Gmc Jimmy Starting Problem
If the engine is using a carburetor, the top gasket maybe leaking evaporating the fuel in the bowl. Check or replace the solenoid switch on the starter body.

it is located in the high pressure AC line at the AC evaporator core inlet. The high pressure line is the smaller of the two AC lines that come from the AC compressor on the engine..
