Just tested the other car's relay with the probe lamp. There is constant power wire from the battery, ignition driven +, negative and the lead to the pump/ecu. On my car, ignition driven + works, but the constant power wire acts like a negative lead.
How can pulling and replacing a relay mess up the wiring so bad ?
Got the power back to the constant power from the battery, the fuse on + was blown. But the wire to the pump/ecu is showing short curcuit to negative. It's blowing the 30A fuse on the battery lead assembly.
Looks like i wasn't very careful when putting back the coil packs and i've accidentally clamped one of the wires which made a short circuit and kept blowing the fuse..
As for the erratic idle/misfire problem it seems that it's solved as well.. The idle is good and stable, engine doesn't skip. The solution for that could be one of the following:
There was a broken cap on one of the injectors which may have caused the injector spray pattern deformation, replaced it. There was also a leftover evaporation box from when it was a TS engine, replaced it with the v6 one which has the evaporation valve on it. It was throwing an ECU fault before since on TS one the was no place for the connector.
Connected the old ECU back, cranked and it fired right away.
