Half bridge R.I.P
Well i just finish swapping out to a new fuel pump aeromotive 340lph, 850cc primaries and 1680cc secondaries and a FPR, now the car wont even start it turns over BARELY wants to fire up. i tried de-flooding the engine removing all spark plugs (clean them till they look out of box) removed the egi fuse and deflooded it, it should start but it still does the same thing, made sure the pump is well set and not coming off the feed line. im out of ideas guys, im so frustrated ive spent alot of money on the car and its been sitting longer then its been on the road, i bought it in july its had 10 miles (around the block) on the chasis im close to selling this =( i have some logs, at my last attempt to turn it over idk if it would help anyone to understand the cause of this problem
thanks for looking over this
(edit) before i swapped out the fuel stuff it started up (just the injectors where maxed)

hey thewird! thanks for the chim, yeah I have a wall plugged battery charger/starter regardless if the battery is at 12.3v the car tries and tries to turn but it doesnt fire up, before i swapped the fuel, it would turn over and id notice that the turbo would try to spin, but now turbo still (no exhaust at all)

@RotaryEvolution: it was the stock fuel, not really the injectors where always over 70% and when id step on it alittle bit, the injectors would climb fast and then my fuel cut setting kicks in!!
@thewird: i quad checked the fuel pump made sure it was pushing fuel , so on the top of the feed and return i unplugged the feed and made my sister turn the key ON, starts squirting fuel like crazy, also when i tell her to turn the car to ON FPR jumps to 40 then drops down to 0, untill the car starts to turn

double check your injector wiring. generally problems like this are related to a faulty injector clip or injector wiring solder/crimp(engine trying to start on one rotor). you can backprobe the injector wires at the ECU, they should all be near 12v with the key to on.
try the starter fluid thewird recommended and see if it responds, indicating you may have one rotor running with no fuel.

one other thing i have seen with 850 primaries is they are not sealed properly to the primary rail, the 850's are a shorter injector not designed to be used as primaries. if they are not sealed the 850's will allow fuel to push into the intake manifold through the non sealed lower portion of the injector through the rail, which would also explain why the pressure is dropping to 0 immediately after the priming sequence is completed.
when i install them i simply double up the lower injector o-ring underneath the pintle cap to seal the injector to the lower portion of the rail(another lower injector o-ring).

UPDATE
well i did an old WD40 trick to it, i stick some WD40 on both of the boost guage and B.O.V nipples on the UIM, the car started ran for like 10 seconds (prob wd40 ran out) then turned off, so atleast now i got an idea, its FUEL RELATED
i want to thank you guys sincerely for chiming in it means alot guys

UPDATE
been doing some hard thinking! when the fuel pump primes i have a 340lph aeromotive fuel pump, i connected it straight to the stock fuel pump feed adapter, i been thinking that maybe when it prines and pushes the fuel threw the lines and makes it to the FPR, by any chance would the fuel be pressured backwards threw the fuel lines and out the adapter? im not sure if the aeromotive comes with a check valve but ima check tomorrow!
