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? |

Run one very large red lead from the battery up to underneath the dashboard.
Mount that to a multi terminal isolation block. Run short red wires from there. Check the ground strap on the rear of the transmission to the body, it's very important. Check the main ground at the fuse panel, drivers side inner fender, way up in there, hard to see, on your back.... It's a simple circuit, ignition needs the right level of power to the ECU or ignition module. Give it that power outside of the entire keyed switch setup and see if it starts first, just use a fused jumper lead. If that checks out and you know the ECU or ignition module is ok, follow that lead backwards. Provide the ECU with a very good ground. Sometimes they use switched ground instead of switched power for an ECU, so read the manual before you wire it up. Build a positive and negative lead right to the battery, test each system. Rich |

I am not sure now that you mentioned it if the ground was done differently or what (IMG:style_emoticons/default/confused24.gif) . |
