Honda Civic vti coupe 1999.
Car previously used to keep stalling and I fixed it with a second hand ignition switch(from here on i will refer to the faulty switch as switch a and the second hand replacement switch as switch b).
Within a few months car started stalling again. Just in case it might be because ignition switch b became faulty too I decided to clean the carbon off switch A, install it and see if that made a difference. It made no difference and car keeps cutting out.
When installing switch A today The symptoms got worse because it seems either I did something during the install or the original cut out problem coincidentally got worse:
Before I started work today(with switch b in car) when i turned the key to accessory on position dashboard lights would come on, you would hear the fuel pump and a click at the end, electronics eg windows would also work. However after I installed switch A What’s happening now is that when I turn to accessory position no dashboard lights, or fuel pump noise, or windows but u do hear a click at end. It is only if you push AND HOLD the key slightly past accessory position do the dashboard lights come and and u hear the fuel pump, windows work etc but if you let it go car cuts out again. At this point I thought maybe switch a is damaged from opening/incorrect cleaning so I’ll just revert back to switch b and the accessory lights should come on as it was before the replacement.
Unfortunately reverting to switch b didn’t fix the dash lights, fuel pump etc issue so i guess it means I did something during the initial switch change that introduced this problem or it could be the original cut out problem coincidentally got worse/worse with tampering and now even the accessory position doesn’t work unless u wiggle it just past accessory. Previously with switch b if I held start position I could maintain running but now even that doesnt work. Is something misaligned?
I did the install while the battery was connected don’t know if that did anything
Based on the above can you figure out what I may have done wrong(tbh switch replacement seems pretty straightforward besides wrestling some harnesses in) or/and what the current problem may be? It think it would be wrong to blame it on me opening and cleaning switch A because I did revert back to switch b where accessories did work and which I had never opened, but despite this reverting to the accessory position doesn’t work properly now.
Thanks
Just to add a year and half ago my car key was so worn I had to fiddle it about to get it to open the door and switch the car on. I lost said keys and automotive locksmith made me a new pair which worked nicely. I think I read somewhere that both the key and the lock need to wear together otherwise might not work. I dunno but just mentioning this history in case it is related. Thanks again.
