S54 no start issue! HELP

Hi Guys!

i have a swaped s54 into my e30. I've had troubles with the dme, flashing it, etc...

finally, i bought a perfectly flashed dmd from frank smith, but my car only start when i spray fuel into the TB, then it runs perfect, idles great and keeps running!

I have 1 bosch 044 pump which is priming on ignition and when cranking, my FPR gauge reads 5 bar when cranking, so there is fuel, but no injectors opening on start up....

CPS is New and Cam sensors are new too...

any idea on what could it be?

thanks!
