Only when its hot

Ok I had this issue a few weeks ago when i had it running before. I stopped for Wendys for the first time in over a month and when I came out I couldnt start it. It was right on a major road so I couldnt hear a thing and I left it to cool off till later. When I returned it started right up.
Now I have been battling a high idle and bad running. It sucks all the time except at idle and seems to shift too fast into second no matter what(Ive gotten a new computer, intake gasket, IACV,opti, Harness,plugs, and wires) Maybe this has something to do with the problem Im dealing with now.
Today I went to return a ICM I tried out(Im bad) and when I came out it wouldnt start again. This time I thought about it and couldnt hear the fuel pump running. I went to get something to eat and let it cool. When I came back ,still nothing. I tried to short the relay cuz I had a regular ol Bosch relay sitting around I used instead of a high$$ dealer part and I just jumped the terminals. Well that didnt work so I used the fuel pump primer wire and that didnt work either, but on both tries I could see a small spark when they touched.
My buddy came out the parts store and I asked him to turn the key as I wiggled the pump connector. It worked then and got me almost home. being as I dont have a dash in I think I ran it out of gas and had to push it about 1/3 of a mile. I dont know if it was the connector or the pump? What does everybody think?

BTW the dash is out cuz Im fiberglassing it smooth to paint it, thats been fun! Always use less hardner then they say! I got a few resin ***** I had to dump

I forgot to say that some of the injectors ohms were off a bit from the others. All on the drivers side got 12.4 and the pass side got 12.3-12.5. Think I might have a stuck injector? How do I check this? Pull the rail and see what sprays? What else can I do?
