90 integra electrical issue
Hey guys any help would be greatly appreciated. I some what figured out that some how it is not getting power to the ecu and fuel pump. i have factored out most common causes. all items checked are main relay, fuses, ecu, fuel pump, and dizzy are fine. dizzy is new. I traced the 2 yellow/black wires to the ecu and hot wired them, as well as the wire to the fuel pump. the car starts, but idles erractically if any other load is used like the a/c or blower and cuts off. could there be another relay for this car that i am overlooking? some how the ecu, fuel pump, and maybe various sensors are not getting power normally. once again any help would be appreciated.
