SR Swap Electrical Problems

[KYZAAC]

i tried to start the motor for the first time yesterday, the fuel pump is not kickin in, i am not getting any power to the dash, the only interior power i get is the dome light, lights by the rear view mirror and the 4 ways, and i have the battery in the trunk, everytime i turn the car over i blow the inline 100amp fuse at the back close to the battery and a fuse up front at the distribution block. i checked all the wires and connections and everything seems good, other then that i have no idea where to start.

Big thing to check is the connector by the factory battery tray. There is a grey and a brown connector, and that's the primary connection between the motor and the chassis. After that, check the connectors for the lower harness. You could have a short within the start circuit somewhere. And given that you're blowing 100a fuses, it's guaranteed it's somewhere in the start circuit.

i removed the whole sr harness and checked everything over, i checked the lower harness, everything looked ok, the only thing not connected is the speed sensor.
would that cause the problem with the fuel pump and dash power too? could there be a problem with the ecu?

Fuel pump could be a relay issue. The ECU turns a relay on which sends power to the pump. The Black/pink line by the battery tray is the wire connecting the ECU and pump relay.

I won't discount the ECU, but if it was bad, Enthalphy would have probably noticed when they were flashing it. Twice.

Double check your battery wiring. Since it's been relocated, it would be the first place I would check. ALL power to the car is supplied through the two lines that connected to the red box on the positive terminal. And a poor ground or a shorted positive cable could also cause your fuse popping issue and lack of power anywhere.

i checked the relay panel with a test light, everything gets power except the EGI Pump relay and the fuel pump fuse.
i had a neighbor check out the wiring, he said the same thing as you, but we checked it out and couldn't find the problem. we hooked the battery back up to the stock setup to eliminate the relocation, all grounds are going to bare metal, we disconnected the alternator, and it was still blowing the fuses. we pulled the harness apart to check any frayed or damaged wires, everything checked out.
is it possible a bad starter could cause this?
it will only blow the fuse when the started is turned over, it will crank for 5 - 10 secs then blow. and the starter cranks pretty slow, even on a new battery.
he suggested to take the starter off and hook it up direct with an inline fuse to see if it blows.

Take the starter out and run it to advanve or auto zone. They can hook it up and check it's power consumption

im in Canada and theres no autozone in my area, but i took off the starter and trans harness, i connected the starter direct to the battery and everything worked perfect.
we tested the lower harness continuity, then stripped all the tape off the whole harness and checked every wire, everything checked out.

a buddy was giving me a hand tonight and he's pretty good around electrical, he eliminated pretty much everything he could and tried just connecting the bare minimum.
the only thing we had connected from the lower harness was the starter and the 3 connectors for the fuse panel, and it was still blowing.

so what does that mean? i thought it either had to be the starter or somewhere in the lower harness, but if the starter works fine and the harness is good to go, wheres the problem?

Thanks for the help man

***EDIT***
well apparently a starter draws 200a when cranking, no wonder the 100a was blowing lol
i hooked the starter power wire to the opposite side of the distribution block to bypass the fuse and so far so good, the wire isn't getting hot or anything.
***EDIT***

now im back to the fuel pump and interior power issues.........

is there anyway to test the ecu? because there is no change what so ever when the ecu is connected or unplugged
