Hypermiling issues: Worn out ignition switch
 

Well I've been hypermiling for a few months now. And just recently my ignition switch has just given out from what I believe has been my Engine Off Coasting/Idling. I drive a '95 Honda Accord DX so I'm not too surprised that it's worn out.

As an aside it seems from internet searching that the Accord ignition switch has a tendency to give out. So it could just be its time to go.

At first I was afraid that I blew out my ECU or something but if I keep the key turned slightly in the START position then my engine runs fine. But right now if it goes back to the ON position the car totally cuts off. I've already ordered a new part and will let anyone know who's interested on how the repair went.

I haven't had any problems with the ignition switch failing. However, my ignition switch did start to get a little rougher to turn after about 6 months of P&G. I used some powdered graphite lubricant in it. Its been smooth as glass since then.

A kill switch can make things more convenient and make life easier on your ignition switch.

I've definitely thought about that. But I've been thinking that I don't want to keep my Accord forever. So at some point I would like to sell it. I would have to think of developing a kill switch that is more plug in style than a permanent feature.

Agreed on the kill switch feature. Very handy.

Also, some cars just have certain weak components. I replaced at least a couple of ignition key switches in the VW Rabbit fleet that passed through my life when I was in high school/university.

Just food for thought:

A big heavy wad of keys will also wear out an ignition switch. Be sure to keep your car keys on a seperate chain from the rest!

i have a standard and if you pop start it then it should have no effect on the starter.

new ignition switch installed
 

I'm back to hypermiling! I took out the bad ignition switch and replaced it with a new one. I bought the new one from Auto Parts Warehouse. I ordered it regular ground UPS and it got here in just a couple days. Decent prices too.

Once upon a time I replaced an ignition switch in a 95 Accord; non Eco Driving Highway miles on the car.

Just a Data point.

I just made a kill switch for my vehicle that is basically 'plug-in' style. I soldered wires to the two conductors of a burnt out blade type fuse, then connected the wires to a toggle switch. I then removed the ign (ignition) fuse from the fuse box and plugged in my new switched fuse.

I also put an inline fuse of the proper value in one of the wires so that the ign circuit is still fused.
