Crank, starts runs rough stalls, check engine light, battery warning light gone

Hi, I got a 2007 Toyota voxy model azr60, it is giving me some trouble, it started with me just getting in one morning, started right up I drove 5 minutes to my church, was there for the whole day, then when ready to leave, it cranks, but no start. I got a guy to come and check it for me at first he thought it was the fuel pump but, he had a scan tool that turned on the pump manually and it worked and I got pressure on the engine. But when I turn the key to the on position I don't hear my fuel pump prime. I replaced my ECU, and changed my fuel pump filter, but all it does now is start one time runs really rough for like 20- 30 seconds but if I give it gas it stalls out and the check engine light disappears and comes back within like 5 to 10 minutes. Also, because of my engine design, I will have to pull a lot of things out of the way I tried using my phone to see what was happening at the back of the engine regarding sensor wiring and I think I might have got something, let me know what you think. All help is appreciated with thanks. The photo with the fingers in it is a sensor wire that i think might be the same thing in the other photo that gave me some trouble once where the check engine light would not come on at all. Cause if you look real good you will see the wires are like exposed and can touch each other and in the next photo I can see a wire exposed so that is where I am now.
