Recently my civic started displaying symptoms of a bad ignition switch. I grabbed my Haynes manual, tore the dash apart and installed a replacement. Trouble is, there were two extra wires alongside my old ignition switch that go directly into the Keylock area. I called a friend and he told me it was most likely aftermarket alarm wiring, or a remote carstarter. So, I cut the wires and taped them off, leaving enough slack to reuse them if they were needed. Trouble is, the stalling at high speeds randomly is still happening. So my question is, could those wires being left in place be causing my problem? Or should I look into the Fuel Pump relay or other possible issues that could be causing the stalling. Dash has no codes, so I am kinda using educated guesswork at this time. Thanks in advance for any help or advice.

Guess you're driving down the road at 70 in high gear and motor cuts off? Does it stay off till you stop and turn it off and then back on to restart? How many miles on car? Just for facts, blue is under dash fuse box. white to underdash fuse box . red is accessories. yellow is fuel pump relay. In that relay is a timer for the fuel pump run without motor running to make sure pressure is at full. Once started, fuel pump runs all the time maintaining full pressure with a bleed off of excess. That way there is always fuel at idle or wot..

Yes thats exactly what happens. No studder or warning signs, just off suddenly. In town it never happens, it almost seems to time up with lifting up on the gas pedal, or when you first touch it to accelerate. 197k on the car. As mentioned, in town its perfect..no issues at all and idles perfectly. Seems to only happen at high speed on the highway, AKA the most dangerous time. Oh yah, I do pull over and start it again. Its never failed to start after sitting for a minute. TY
