ok so this happened early yesterday morning.

i have a 1998 accent gsi

I was on my way to work at 3am just like always. I got about 6 miles down the road turned the heater on and bam lost all electrical and 2 seconds later the engine shut down. I have not had any problems before other than the check engine light was on for about 2 days (i do have a cheap cone filter on that has thrown the MAF code before so assumed it was that again). When i crank the engine you can hear it acting like its starting (starter as well) but it doesnt start. the weird thing is i tried to hit the emergency flashers and instead of the normal clicking noise it has like a buzzing noise like not enfu power is going to it, tho when starting the car it doesnt sound like there is any power loss at all. we are thinking it might be either the crank shaft sensor or the camshaft sensor .... any thoughts?



thanks all for any help, i need to get this running so i can go to work the next few days.

So did you test the battery?

Sounds like a serious electrical problem. Not enough power getting to it = either a bad battery (which you've already tested), a failure in power delivery, a bad ground, a short somewhere drawing huge current, ****, maybe even a bad ignition switch or stuck relay.

When starting the car, it disables everything but the ECU/injectors/fuel pump. Which means you could probably get by with disabling EVERYTHING except those few things. The best thing to do in this case is to pull out every fuse you can find (remembering where they all go) except for the fuel pump, starter, and ECU fuses, and slowly add fuses back in until the issue pops up again.

The flashers is a good place to start if the fuse trick doesn't work. Probe around with a multimeter (for the $10-20 it will cost, it's definitely worth it for this job) checking for the quality of the ground and the voltage coming from the battery. Start playing around with other accessories (check the blower? Radio is a common culprit?) There is a slight chance your ECU may be damaged, especially if the problem was caused by overvoltage from a bad alt.

In my '96 Accent, if I have the heater on full blast, my radio signal is reduced and sounds fuzzy (though my car's antenna broke off).
