I had a similar problem a year ago. I thought it had to be this, then that, then since that didn't work it must be this. Nope, figured it out when I bumped the fuse box with my leg. The fuse for the ignition was not blown, BUT the little metal clips inside the fuse box were loosened. All I needed to do was pull the cover off of the fuse box and squeeze the clip with needle nose. Spent a butt load of money to fix it when it ended up being a $0 fix! ARGH!
