Help!! ka24de

[Datsun510]

hey guys im new to the forum and would like to see if you guys could help me with my 91 ka24de. im from san diego cali and own a 71 datsun 510 with a ka. the other day i was cleaning the wiring and must of moved a wire cause now the motor doesnt want to start. if i turn the ignition and step on the gas it starts but idles rough. if i dont step on the gas pedal and just turn the key the motor wants to start but dies. i checked all my wiring and it looks good. theres an orange wire that goes from the ecu to the starter solenoid. it was always connected but now if i disconnected the car starts without me having to step on the gas but still idles rough. if i connect it it doesnt start. do you guys have aby idea what it could be???

check for vacuum leaks.

this a AT or MT?

Its a 5-speed. when the motor is cold i have to connect the orange wire to the starter or it won't start. once the motor is warm i have to disconnect the orange wire so the motor can start without me stepping on the gas pedal.

try to reroute all the wires correctly.

i think you wired something wrong.
