dsm 450 injectors problem
 
heres my problem i recently installed a safcII and when i installed my 450's the car just wont start my settings are

pressure
6in 6out
4 cyl. arrow ^to the right
1000 t0 4000 -40
5000 to 7600 -35

now when i switched the injectors back to the stock ones it ran but not well because of the settings i thought maybe the map sensor wire was messed up so i then disconected the safc and it threw a code 3 map sensor so thats ok ,so is it possible to have 4 bad injectors i got them from a local junkyard so who knows how long theyve been there i just wondered if anyone else has had this problem or has any ideas as to why this is happening its the last thing to finish my turbo project ,also the car is a 90 crx si with a pg7 89' teg computer and a obd0 dohc zc motor ,thanks guys for any help

I have seen injectors stick from sitting with fuel in them but all 4? You can turn the key on to presureize up the fuel rail and stick 12v to them with the injector disconected and useing jumper wires just pulse them quickly( dont leave it on) and you will here if fuel goes in the intake, then move to the next one. Cycle the key before each one cuz the pump doesn't stay running.

if they were sitting for a while, they might be clogged.
clean them:
