    Won't start with key

    Ok guys, seeking some advice on where to start (no pun intended). I have an 84 318i and picked it up non running. I put a new battery in and jumped the starter and she fired right up!

    However the key will do nothing to engage the starter. No click, nothing. So am I looking at the switch itself or is there something else I should look into?

    It might need to be noted that the ecu has been replaced by the previous owner, I tried with the new and the old with the same results.

    Are you getting accessory power when you turn the key on? Is the new ECU pn: 13611706453?

      Issue resolved. It was the ignition switch. I traced my no power issue back to there, swapped for a good one and she fired right up.
