What I woudl like you to do is disconnect all other injectors then check #2 again for pulse with a noid light.

No pulse check for +12v key on and -12v pulse.

If one injector has too high resistance itll stop the other one from firing, thus is why I tell you to disconnect it.

Blacktop-been down the noid light/ power check road- I need to know where the injector wires connect so I can trace/replace shorted wire.
Thanks

Bellowdiagram will show where it hooks up, if you cannot read here are where they hook.

#4 injector
lt grn-wht wire connects to pin 61
yel-wht splices to injector 3's yel-grn wire.
#3's lt grn wire hooks to pin 60

#2 injectors yellow red splices to #3's yel-red wire.
and its yel-blk wire hooks to pin 52.

#1's yel-blk is spliced to #2's yel-red wire and its yel-blu is hooked to pin 51

all pins are on the ecu, to test do pin to pin not backprobing.
