Hey guys, me again. Just wondering if anyone can help me out with a little problem i have ran into. Only 3 cylinders on my motor are actually getting gas and firing up. This is on the right side of the motor if you are looking at it from the front. the other three are getting tons of spark but no gas at all. I checked the injectors with an ohm meter and all the injectors were identical. I also checked the 6 wires going to the injectors through the junction plug just before the injectors and tested each wire for voltage while the motor was cranked over.

The Pink and white (A) wire seemed to be constant power at 11.59V

Green (B) was at 0.15V

Blue (C) 0.15V

Orange (D) 0.00v This wire has nothing at all. Dont know if it needs to lol.

Dark Pink and White (E) around 9.7V and 9.9V

Beige (F) around 9.7V and 9.9V

If anyone could give me a hand with this that would be awesome. just seems to be one of those great wiring issues. thanks allot.

Did you check the fuses? There's one for each bank of injectors.

yup thats her. couldn't read the lettering anymore on the panel lol.
shes running good now lol. I just need to figure out what is smoking a bit. think its a wire or something. time to go under her again. thanks a bunch, overlooked the fuse cause i thought all the injectors were one fuse. thanks again. hopefully now i can make it to the meet.
