Flashers start flashing for no reason and then the car won't even try to crank over. Someone suggested a security condition. Even after getting the flashers to stop, it still isn't cranking over. Battery voltage is good.

 

Did you try pulling the negative batt. cable off to try and reset things...???

 

yes...but to no avail.

 

flashers? is your starter ok?

 

A lot of 95-96 Maximas are bad for the ignition switch going bad. When it happens, it happens pretty much all-at-once & it makes you think it's something with the security (no starter noise/battery click at all). If you've felt just the slightest looseness in the ignition key recently, I'd bet that's what it is.

 

You know....after thinking about it for a while...I think that there's an aftermarket security system in it. I just bought the car a couple of weeks ago for my daughter. Everything was fine with it for the first week until I wired an amp to her head unit. I also remember an alarm/horn until the hood that the previous owner apparantley snipped the wiring on. All that to say, I suspect that the vehicle is in theft deterrant mode and there's probably something goofy behind the dash that is opening a relay that passes the ignition switch output to the solenoid switch.

My daughter's boyfriend said that he saw some cut and spliced wiring behind the radio cluster when I was wiring in a new head unit yesterday.

 

I meant when "he" was wiring the new head unit.

 

Ok..problem solved! There was a faulty aftermarket motion sensor that was killing ignition switch 12V from the solenoid switch. It also was causing the flashers to flash. After unwiring it, normal operation returned.
