Okay, I hope my dyslexia doesn't take full effect here, I have changed the starter, the cam shaft and crank shaft position sensors. The battery is a good battery. At first a faulty starter caused a bad ignition switch which I replaced, and I replaced the starter. I made the mistake of telling her that once she got parked, she could rest. Well now she is in a coma. The only sound it will make is the fuel sending unit sending fuel up. I have replaced every single fuse with brand new ones. All the lights work and the only dash lights that turn on is the check engine light. That light has always been on for the 02 sensors and I have replaced the two that were bad. Please help, I beg of you; I didn't take the Just Empty Every Pocket seriously. (Jeep)

Lol yep, So the engine cranks and does not start or the engine does not crank over, correct? With the key on can you check for power (both sides of the fuse) at fuses # 3, 7 and 8 at the main fuse panel under the hood.

This guide can help:

So it’s completely silent other than sending fuel up to the engine. Thanks to going through this site for a while I had came across a video that showed me how I could see if my starter relay is bad. Which all fuses are getting voltage and I have replaced every single fuse in each fuse box with new ones. But I’m like baffled because if this video is correct it’s like a whole 180 back to where I started with it. I am able to take one wire about 5 inches long and splice both end of it and put both ends where the big black box relay fuse is supposed to be and the Jeep wanted to start to roll over after that but she wouldn’t start. In the video the actuator pin in the ignition switch was broken. I am 100% on if that is it but it doesn’t hurt to check honestly for all I know I just need to do a whole look down of all of sensors and the wiring harness. That is the next step.

Okay so it doesn't crank over. Let's use a test light to see if you are getting power to the trigger wire of the starter when in the crank position. This guide can help and here are the starter system wiring diagrams so you can see how the system works.
