sence i was getting a code for the IACV i started to trouble shoot it, First i pulled the connector on the IACV and check for batt voltage on the #2 vin and it was good. Next i checked for voltage on the # 12 pin on the A connector at the ECU. That was good, the next thing my helms tody me to do was put a jumper wire between 12 ans 10 on the A connector and listen to see if the IACV clicks, well i jumped the wires, got a huge spark and nothing. But now i have no power to my radio, turbo timer and no power on the 12 or 2 pin? All fuses are good and i can't figure it out!!!
