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!
