Yea, I've jumped other vehicles with this car before - always extremely careful. It's "probably" a coincidence, but...I've checked all fuses - even the 2 on the OVP (and swapped out the OVP, just to be sure). It doesn't feel like I have spark...I'm going to try and get to testing this today.
I am very much aware of the ignition issues and this particular EZL is really hard to find (M104 motor)...
After reading about how difficult it was to rebuild these EZLs, I ran across a company online that sells remanufactured ones and will rebuild your old one - Rebuild Master Tech - anyone familiar with them?
