This is the 2nd time this happens thats why Im here. Today I was there in traffic waiting for the light to go green. The car just died on me. So I go to start and it doesnt even turn over, there is no power anywhere in the car (hazards, lights) nothing works. I sat there about 5 mins under the hood following wires and found nothing out of the ordinary. Then the lights pop up and its all normal again. If it was a short wouldnt it have drained the battery. I have not had any starting problems or any battery draining problems. From what I spent time searching I didnt see any faulty wires either. Something with the ECU maybe?? Anyone input is apprecaited.

I've never heard of an ECU cuting in and out. From what you described it's definatly something that has to do with power being supplied to the car.

My old truck would cut out sometimes and just not do anything just as you described. I'd suggest making sure you have a very tight and secure attachement with the batter terminals. If there's any acid on them clean it off and put a little coating of grease around the terminals to ensure that any acid that might come back doesn't.

If that's not your problem, follow all the wires coming off the terminals and inspect them closely for any kind of short, kink, etc.

One thing that's hard to understand tho is why your car would just die from failure to deliver electricity, if anything your radio etc. would just shut off, not the car.

I dunno honestly, never happened to me. Never hurts to check what I suggested tho. Hope it helps.

I've had simular problems.. Check grounds!!!! I cant stress this enough. mine wasnt grounding properly..

Thanks Kyle for the input, yes I agree with your comment only the radio or something but its the WHOLE car its so dam weird. The terminals are clean and very tight. I think Godzilla may be right and its a ground. LoL OH NO all that wiring to check .

HAHA welcome to owning an FD

Yea, he definatly made a good point, check the grounds. I didn't even think of that... tho I don't see how that would make the whole care shut off? I dunno... I'm seriously stumped on this one.

First time it happened I was on an incline going into a parking lot (dam thing almost rolled back into the street LoL) but not this time it mid traffic thats what I thought weird. Would a short drain the battery?? One more thing the ECU doesnt have any fail safe against shorts or something maybe??

On other cars when I've had a short, it's killed the battery (namely my old 300zx going down a hill ). Yours sounds more like a bad battery cable or connection to the battery.

Nah definetly not battery thing is bolted on good, maybe I can check where they lead to.

Never rule that out. Same thing with my 300zx. Everything looked fine, however the battery cables had a short inside. A new battery (since the short killed my battery) and new cables fixed the problem. Unless you have x-ray eyes, looks can be deceiving sometimes.

Hmm good point, maybe some wires are fried or are old. I should take a look at some of them and see what condition they in.

They not just buy some new grounding wireslike hyper grounding wires?
