Default 240sx info

when i turn my ignition on and the fuel pump primes, the fuel injectors start spraying gas for no reason. The injectors are pulsing when the key isnt even in the car and it causes my battery to die. Like i said though what could be causing the injectors to pulse when the key isnt in the car and its just sitting thier. Somthing is sending it a signal telling it to spray i want to know what all could be causing it. Im not a nissan guy im just trying to help my friend out its his car its a 240 sx . so any info will help

Injectors recieve 12 volts at all times, and are grounded by the ECU for a period to make them fire. Somehow, those ground wires are being constantly grounded.

I would test the pins on the ECU, that would help narrow it down.

Hope that points you in the right direction.
