5ktq electrical problems update (not fixed)

[Cody Forbes]

I trust the EFI readings because I have checked it multiple times vs a
multimeter connected to various spots including directly to the battery.
Every time I check the EFI is within a tenth (usually a few thousanths off
to be exact) of a volt of the battery. Even so I do also check with my
multimeter at the battery directly usually. No voltage drop at speed, it
stays solid +/- 0.1v from 13.5v no matter what the engine speed when all
accessories are off. The cars main supply is fairly good it seems, the only
problem is voltage supply to the ignition I think.

Can you see the voltage when yer at 3000+ RPM? If the voltage is the problem
you should see the voltage drop then. I'm not sure I'd trust the onboard EFI
voltage reading as much as a meter...

Those injectors are pretty big too. I wonder if you need a better set of
power lines to provide for the large injectors. You might have to bypass the
fuse panel connections altogether and see if voltage direct from the batt.
or alt. lines will help. In any case I'd check for the voltage drop at speed
first before splicing anything.
