ok im boosting my 90 wagonvan
has d16y motor
50 trim
450s (dont need box)
problem!!!!!
i had the wagon runing with oem injectors. 5 mins b4 all this
i was told that the only way 2 get injectors that dont need the resistor box to work is 2 splice all 4red wires 2 the 1yellow wire, did this and then i took the 450s put them in and there not spraying, i cant hear the fuel pump prime now either, not geting fuel at the rail now also. what is the prob??????

 

why not get low resistance injectors in the first place?
but yeah, cutting off all the wires off the resistor box wiring and soldering them together should work. 5 wires total all together.
Use a volt meter to check for voltage @ the injector plug to see if you're getting power to the injectors.

 

People run DSM injectors because they're pretty much free. Anyhow, I agree with the rest of your post.

 

thanks guys. yeah the reason im using these injectors is for this reason only(i already had them)
im trying 2 get a set of dsm 440s now.
what should the voltage be at the injector clip. 12v? or lower? and at the 1st ign stage?
thank you guy

 

ok i was not geting fuel 2 the rail(bad main reley) fixed that. now i put the d series injectors back in car start up fine. just worried about messing something up agian, trying 2 get dsm 450s now
