ok so i just got a new fuse box and started to wire up the different circuits, currently i have 2 of them
1.gauge circuit which includes my boost/AFR/ECT/OIL press/ Boost controller/ Turbo timer. This circuit is only fused with a 10 AMP fuse, grounded at the fuse box ground terminal
2.Injectors, Ls2 Coils, Stand alone circuit which includes just those. This circuit is Fused with a 20AMP fuse and is ran off a 40Amp relay. I have the power side of the relay coil wired in parallel to 2 other relays " which are currently powering nothing, but one of them will power a fuel pump" this goes for the ground side of the relays coil to. the switch side of the relay is then powering the Injectors/Coils/and stand alone, the two grounds off the vi-pec and ls2 coil "sequencer ground" are wired parallel to the ground bus at the fuse box, and i have a separate lead going from the LS2 coils "ground near coil" but it's wired to the ground bus at the fuse box. "only because i dont have a ground strap wired to the body and engine of the car yet.
The problem.
When i go to test the Injectors it causes my Gauge circuit to go crazy "the boost controller turns on and off with every pulse and the AFR gauge bounces up and down, and the turbo timer turns off and it sounds like the pulsing from the stand alone is going to that." when i pull the gauge circuit fuse i can still hear a ticking noise "like an injector firing" inside the turbo timer. So then what i did was i just fully disconnected the ground for the gauge circuit and tried again, when i told it to test inj. pair 1 it then caused the stand alone to go offline "or at least it lost USB signal" and I think the relay started to flick on and off. Currently the relays coil side aren't wired to fuse box ground i just temporally ran the wires directly to the battery.
battery was on the charger so i was getting 13-14V
I Triple checked the wiring and there shouldn't be any shorts.
This problem happens when testing the Injectors but it is alot worse when checking the Ign. coils
could the problem be
1. the coils grounds are both currently wired to the same spot as the vi=pec and gauges?
2.Because i have 3 relay coil side's wired parallel?
Here are two diagrams i quickly drew up to show you the circuit
