Factory alarm causing fuel problems?

[300ZxProdigy]

my fuel pump wont turn on. If I ground pin 18 (fuel pump relay) the car will run fine. Any ideas if this is a problem caused by the factory alarm?

I very much doubt the OEM alarm is connected to the fuel pump in any way. I think you must have a after-market alarm or kill switch problem.

it could on my old car the alarm was going off or not disarmed and my car wouldnt start i had to turn the key in the door and disarm it. It would just turn the interior light on and stuff but the car wouldnt start as if u werent putting the cutch down and the fluel pump didnt prime

Maybe the Fuel Pump Controller is shot
