okay so heres what i have going on about 2 weeks ago on a snowy saturday night i went out sliding was a blast got home, car didnt give me a bit of sas all night. parked it for the night and went inside this was about 9pm est. woke up and went to start the car around noon and all it did was crank so i was like wtf

.so i got a buddy to get a torpedo heater and sat it up so it would warm the car up because i thought the fuel lines were frozen because how cold it was. i noticed the fmic was a solid ice brick so i also heated that up. after about 2 hours i went to go start it again still nothing so i left for a bit got gas in a gas can and came back. took off the cold pipe from the innercooler and put a tad bit of gas in the intake and started it up she ran for a couple of seconds and shut off. did it a few more time finaly she ran at idle fine with the cold pipe off but as soon as i tryed to put the cold pipe back on it died. well with enough reving it up and trying to put the cold pipe on with out it stalling it finnaly ran perfectly fine with the cold pipe on so i drove it around thinking might of been bad gas or something and parked it. woke up monday moring to go to work at 10 and she started i let her idle for 20min and shut her off went to work usally i would drive her but i didnt today got off work at 730 and got home around 8 went to start her up all she did is crank it wasnt to cold out either and she hasnt been moved at all so i was like wth? left to do something got back home around 9 and went to fire her up and she started. got up tuesday morning she didnt start again so around 10ish i got her started with the cold pipe off once again and drove to my work about ten minutes away with the pipe off all the way there. so this is what i have tested
cas: good took it out and spun it inj clicked.
fuel: 45psi
spark
air
this is what i have found out i have checked the ecu it looks to be good it has fuel all the way to and threw and back out the fuel rail but the injectors are not firing. injectors are good i got another set and still nothing. so the only thing i can think it is is the wiring any ideas?
