Check by lower rad hose in engine compartment, in fuel line.

Computer maybe, but it's not the most common failure. There is a hall switch and a "pole piece" on the shaft of the distributor just under the rotor. The ignition module just to the side of them usually affects spark. Sometimes it's easier to swap the distributor assembly if you know the procedure.

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.
Testimonial: "great info, thanks!"
SOURCE: the starter is locked up on my 94 jimmy gmc. how
sometimes just by banging it with a hammer itwhile startuing it may unlock, but usually a locked starter means that you need to shim the starter so that it turns evenly to the flywheel
SOURCE: 1999 gmc jimmy w 4.3 v6. cannot find oil filter
look under the front of your blazer, just below the bumper, and you will see a little access door in the plastic guard. Open this door, and you will find your oil filter.
