car: 2000 trans-am ls1

ok so first ill list what i have done to the car, then what is going wrong. so that you can have a full idea of what might be going on.

*replaced:
intake gaskets
torque converter
starter
throttle body
throttle body sensors
egr & air delete
fuel filter
racetronix fuel pump 255lph
oil & transmission fluid
transmission filter
pcv oil catch can
new battery
this is all the new stuff.....

*old mods....
slp lid
02 sims
cat gut
msd wires i made
3" magnaflow cat back
all free mods

*i have the hot wire kit for the fuel pump but i haven't put it on yet

*tried blowing compressed air threw the lines to clear out any old gas that might have been in there (disconnected line at motor and filter)

injectors where all clogged i cleaned them and now all injectors are operating
tested with noid light all injectors are getting signal

current problems im now having:
***UPDATE***
the car is only getting 40 psi @ the fuel rail,
**update: after cleaning injectors they fuel rail pressure is now @ 35 psi with a very slight leak down in pressure

coil 4,5,7,8 are firing. 1,2,3,6 are not firing checked via spark tester (swapped coils around same cylinders firing)
car tries to start after i turn the key for about 3-5 seconds then dies
********car is now not cranking over and it is backfiring out of the intake also blew out my valve cover gaskets*********
idk if this could be part of the problem but this is how my pcv is set up after air & egr delete


**results for "trigger wire" from pcm to coils and spark test without "plug wires"


also the "check gauges" light is on idk if this matters ?

also car was setting for bout 3 years
