Okay so my wrench called last night. Car was all finished & he went to fire it up. Turns over fine but no start. This is what it was doing before the fire. Also off & on it has plagued me since I got the car. I've replaced the ignition with multiple times. I added a push button for the starter to take that off the switch. Seemed like there was to much power going through it which I thought was from the starter. Obviously it is not.
One thing is almost without fail as soon as I put in a new switch & use it I get smoke from it every time. It would be fine right after the brief smoke so I didnt worry to much about it. What else is feeding the ignition switch that may be pushing to much power through it? What do you guys recommend doing here? Cutting out the switch completely? Do you think the problem lies somewhere besides the switch? |

I'd like to clear things up a bit…..I can say without a doubt that there has NOT been any smoke or fire since I've been working on it.
I removed the stereo and accessories ports to be sure that they were not drawing a load. Now its just the cars main harness and ECU.. The Battery is grounded correctly, The ECU is grounded directly to the battery and the fuel pump is grounded. I've even replace the transmission to chassis ground The fire was centered around the battery and I feel like it was caused by a cable rubbing on the oversized battery tie down and shorting out. That sent the heat up to the ECU via a horribly routed wire harness and down to the firewall where the main harness exits the cabin. It was all one big melted mess of wires. Everything has been cleaned up and patched properly. My next step is to replace the ignition, check the main Yellow wire for anything that looks suspect and ad a 30amp fuse to both the fuel pump and the starter and of course, continue to look for a bad ground while Im in the dash.
