for those who did reply to my post

i didn't see the original post but we have a pro-touring duster we built that has always had starting issues, at least for the owner lol... never gives up issues...

but anyways, i just wired in a relay, the trick is to find a switched hot that WONT completly lose voltage during cranking.

so what i did was wire a direct line from the lug on the starter relay to the relay, then to the MSD so now your MSD will have power

now probe around and find a wire (think it was a ign circuit) and splice a wire from that to the relay. from there you can go right to ground. if you cant find a good switched power you can run switch and just put it on the ground side...
