This seems so complicated. I like to take a step back.

  1. Can i see the injectors spraying good amount of gas? Yes then go to step 2.
  2. Am I getting a good spark. Well only way to test it is to pull the spark plug out and hold the God damned thing up to the block. Honey start the God damned car. If you can make that ************ arc 1/4 inch go to step 3.
  3. If I got the God damned gas and I got the God damned good ass spark. Do I got a mechanical problem.
Do you have a photo of your arc?

Fuel pump isn't giving me a solid 9-13 lbs. Forgot to post update, can't fix right now due to hand injury, so it'll be out of commission for a good long while
