Hello again Scotty, I am still trying to get my 1998 GMC Sonoma 4 Cylinder to fire, but it still won't. I have replaced the spark plugs, spark plug wires, both ignition coils, and just today the crank sensor. I checked to see if I am getting fuel and I am so I believe I have covered everything in the video you sent: https://www.youtube.com/watch?v=064Ilsz8Fzg . And, of course it is turning over/cranking just not firing up, still making the same cranking noise it has every time I have replaced something else. Please let me know what else I can do to get it to fire. Thanks!

if it has correct spark and correct fuel pressure and the injectors are firing fuel into the engine, either the head gasket is blown, or the engine is flooding out from fuel injectors pushing too much fuel into the engine.
