Crazy electrical problem

This is my first post...I was driving down the interstate one day...55mph 5th gear....car dies with no warning once I check it out i see the engine module fuse is blowing so I replace it...it blows whenever I turn the car over...however it will not blow if your not trying to start the car. There is no aftermarket wiring and I have checked everywhere for shorts whatever is shorting out is big. Also i am getting no spark naturally because the fuse is blowing...i know nothing about electronics i think it might be a bad ecm if anyone has any advice i would appreciate it

You have a short to ground somewhere, replacing the fuse doesnt do anything, dont put a higher amp rated fuse in there either. I would suggest taking it to a mechanic unless you know how to use a volt meter and read wiring diagrams.

A 1G ECM can be bought on eBay for $100 and a 2G for $200... I'd check all the wiring that I can, and if it's not outside of the ECM, it might be cheaper just to replace it. ...That's what most mechanics would do around here anyways. :lol: Other than that, you can't hurt anything with a volt meter (just don't lay the metal contact across 2 wires)... Right now might be a good time to learn to read a wiring diagram. PM me if you have any trouble with that.

thanks alot for the post. I haved followed and tested everybit of wire that there is. So it must be the ecm. If anyone can shoot me a link where i can get one for around 200 i would apperciate it

did you check your major ground junctions?

I just got this same problem... its not the ecm so theres a wiring short some where. Does anyone know where I can get a wiring diagram for a 95 gsx?

on ebay they sell the dsm shop manuals on cd. Those have wiring diagrams. They are simple to follow and cheap. I think mine was $10 shipped.

just had a problem just like that. it was the ecu on mine. found one at a junkyard. after buying a blown one of ebay.
