S14 No ACC Power/Start - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Silvias14.5.0 · 06-07-2013, 11:44 AM

Hey guys, it's another 240sx with starting issues so heres a little background of what happened, I removed the dash to install my heat and air ducts. I found out i didnt have all of the components so i said screw it. Installed everything back in and no when the key is turned the car will not start, i have no accesories like the radio, windows sun roof, but the door chime and headlights/taillights work. Checked all relays and fuses everything is good, but im not getting power to the left side of my kick panel fuse box. Tried the ignition switch but no luck also my ecu was never remounted by the previous owner so in this process it may have had a few bumps. PLEASE HELP!!!!!! If anybody has any ideas please throw them my way im at a complet loss and im going to try the a new ECU next.

you forgot to hook something up. Engine bay fusebox may have the fuse you're looking for, it's one of the big ones. check for corrosion on your battery or a loose terminal. It's a 25 or 30amp fuse that tethered wire going off of the positive battery cable is what sends acc power. None of that is hosted in the cabin

i have a battery relocation to the trunk and as far as i can tell everything is hooked up except for one connector that comes fromt he ignition which a 3 wire plug with a yellow, orange, and red wire going to it but i cant find where it plugs in at

and its not just the acc power but the fuel pump isnt kicking on and when i turn the key the starter doesnt try to kick over at i dont even get any clicks it just does nothing

Om1kron · 06-07-2013, 12:25 PM

its not going to kick over because acc doesn't have power.

Silvias14.5.0 · 06-07-2013, 12:29 PM

All of those fuses have been checked as well all relays and all fuses are good

Silvias14.5.0 · 06-08-2013, 12:46 PM

!!!UPDATE!!!

Changed the ecu and we are still not getting any power to the acc nor the fuel pump. I am at a complete lost here guys I am really in a bind and need some help if anybody has any other ideas let me know im about to go through and just change every fuse and relay

Silvias14.5.0 · 06-12-2013, 05:04 PM

So I'm thinking ignition relay in my car my be bad because i have no power to my ignition switch through the constant or anything also to any of the acc fuses in my kick panel fuse box. So the next question is do i change both ignition relays if so which ones or they and maybe even the clutch interlock relay

Same problem happened to me. My solution was the alternator. Started right up. Good luck
