2000 GMC Jimmy No spark

I'd check the small primary wire circuits that go to the coil. Two wire connector, Pink wire goes hot when you turn on the key, the other is ground, should be a pulse on the ground with the engine cranking. You can take the connector loose, use an led testlite between the two terminals, crank the engine, see how the testlite reacts.

I can't tell if your repair work might have caused a problem? Is there an rpm signal? Any codes? With the engine cranking is there good fuel pressure and injector pulse?

Did you check the primary circuits going to the coil? What did you find?

The rpm signal comes from the crank sensor. If your using scanner that will show live engine data, it should show an rpm signal, with the engine cranking. Without that signal you get no injector pulse, the fuel pump relay won't energize other than the initial prime, and I don't believe you'll have any spark. Don't replace the crank sensor without doing some basic tests on the other systems.
