Unloaded the truck easily at home and pushed it back on the
side of my house for the real work to begin. It cranks good and has a strong
battery but is not firing at all. I checked the spark by using a spare spark
plug and removing one plug wire at a time and checking for spark. There is only
a little yellow spark not a bright one. I tested the coil using some
instructions online and found that the coil did not match the correct specs
that it should have. I got a new coil and swapped it in easily but I was still
not getting a good spark. Oops no new coil needed, I guess I will have a spare.
Troubleshooting did not go very well so I called in some reinforcements with better tools.

I have figured out its not the ignition at all. With the help of an inline spark tester it finally shows a good spark. I guess holding the spark plug on the valve cover was not quite good enough way to test.
We used a compression tester next and the best cylinder was at 15 psi and the worst was about 1 psi. I find it hard to believe an engine could get this bad in each cylinder so I am going to take off the valve cover and test valve lash and check the timing chain to see if it has slipped a tooth or something like that. Sounds like worst case I will be getting to learn how to rebuild an engine.
