Remove the INJ1 and INJ2 fues, are the pink wires still shorted...?

PCM unplugged fuses and IGN relay in place key off and on - yes

PCM unplugged fuses removed key off/on - no

PCM unplugged relay removed key off/on - yes

IGN relay pin B3(red) - open to ground(good)
IGN relay pin B1(black) - closed to ground(good)
IGN relay pin C1/C3 - closed to ground(bad)

basically, all pink wires and some yellow wires that are connected to them
are closed to ground key on and off.

probing around fuse box #2 (under hood lower)
i found that all but the starter fuse was closed to ground
i removed the fusible links and they (fuses) are still closed (audible)
the fusible links are not closed to power or ground.
also the PCM IGN and ABS IGN have a muted audible,
the rest are clear.

this is with the positive linking wire (short red between fuse boxes) disconnected.
if i do have a short it seems to be inside the car.

Check the fuse panel on LHS of dash.

i have checked all i can.
every pink (hot switched) is audible to ground.
maybe somewhere there is a melted wire.
everything seems to work fine though,
all lights, and the stereo come on.
the SES and check gauges light stay on.

i am trying to think of a common point for all pink wires.
even with the I/P and lower fuse boxes disconnected from each other
all pinks are closed to ground.

LOL
i'm surprised no one else has had a similar problem and seen this thread.

i unhooked the 3 grounds on the back of the cylinder head
and 1 of them is open to ground and to the fuse box.
it is completely dead

What color is is...? Can you identify which ground circuit it is.

it is G112 (550) and it loops to the others.
i.e. when disconnected and isolated it will be open because
it needs to be in contact with G110 to be closed.
this was a false alarm.

i made sure by checking the coils to it and they are closed.
all pink wires being closed to ground seems to be the issue,
unless they are supposed to be.

[mr.prick]

now that i think about it,
shouldn`t G110 (451) and 450 be open after it is unhooked from the cylinder head too?
it is closed to the main ground.

[mr.prick]

i tried connecting the DMM- to the battery+ and the DMM+
to the lower fuse box and, it read battery voltage.
the upper fuse box does not.

i have checked all grounds now and the connectors look normal
and they are tight.

what is the bare minimum wires to be connected to the PCM to flash it?
i will pull all the pins that are unnecessary so i can upload a tune.
