Car wont start

[idonthavea240]

Ok just finished the SR swap.. got it all wired up double checked everything and it was all good. Start it up and it runs good.. shut it off and then turn it back on. Still runs good and starts up without hesitation. We let it run for like 10 minutes to check for leaks and to see if it overheats.. Everything is Perfect... we turn it off and on a couple more times without any problems. So we go take it for a test drive works perfect still.. come back to the house and shut it off but go to start it again and then it wont Start!! we check for spark, fuel, mafs, grounds, blown fuses, ignitor chip, and anything else we could think of. A buddy started moving wires around and then we try to start it and it starts right up. He drives it and comes back and same problem it wotn start back up.. this time it wont start up after doing everything again.. It cranks but wont start up.. also we tried unplugging 1 injector and starting it and it starts up but runs nasty and when we plug it back in it shuts off.. also we unplugged the main wiring to the car and cranked and then plugged it in and it starts to start up but then dies.. We have no idea what the hell is wrong with it.. Thank you for any help!!!

what wires did he move around?

the ones by the fuel injectors... there are like 15-25 wires.. weird thing is i just picked it up tonight and it started right up... a couple people have suggested that its a bad engine temp sensor and thats what it seems like because when its cold it will start right up. and the temp gauge is showing that it isnt overheating sooo hopefully thats the problem
