Okay so I finally got my car to start but I had to do some tricky thing. The only way to get it to start after a few hours of not running is to ground any injector with my own wire and keep tapping it to manually spray some gas while someone cranks it then it will start up. I'm thinking this might be some bad gas or something like an air pocket gets in the fuel rail and me tapping it gets it out but I have no idea really.

After i do this i can shut it off for a little while and it will start right back up. Is there some other reason that manually grounding the injector will cause it to start other than bad gas?

What is the injector resistance?

Does the fuel system hold pressure for more than ten minutes?

Does holding the accelerator to the floor while starting help at all?

Check your TPS settings to make sure it is not stuck at WOT (clear flood mode).You might want to unplug the TPS and see if it starts.
