2002 Toyota Camry cranking but no start. What's the issue?

I have a 2002 Toyota Camry XLE. And it has the 2.4 I inline 4 engine. I've recently come across an issue and I'm hoping that someone here can help me with the situation. I've come across a problem where a week ago the car would start really rough and then misfire crappy and then just die. I have replaced spark plugs. I've replaced these temperature sender sensor. I have replaced the crankshaft sensor. Nothing has fixed this issue. was testing spark last night and the coil packs are not sending any spark to the car. Before this issue I read the codes. The codes were as followed random misfire, misfire and all four cylinders, random misfire again, and then the ignition circuit fault in all four cylinders. When I was testing spark in the 4th cylinder. And I lifted up on it near the wiring harness. The car fired up for about a second and then it died. I checked the wiring harness. I've checked where the wiring harness goes and everywhere like that and there is no faulty wiring. Is there anyone here who can help me with this. This is my last hope.
