help diagnosing 2001 Chevy Silverado

I will try that stuff. Thanks.

Where in the heck do you get the "forked fuel injector assembly removal tool" that the fixit manuals call for?
 
Well, we tested compression and vacuum and both were great. We also tested the coils. Pulled the black plug and cleaned it and then replaced the injector on that port. The truck starts great now and the plug looks normal after driving. Best of all, the code P0300 has not come back. Thanks, guys.
