no vac leaks... Not a coil issue switch the coil and igniter out with a couple different ones. I really was hoping it was the distributor too. Runs for about 5 seconds then just like dies... and when it does run it seems to run pretty good and strong. If i give it throttle and hold the throttle open it will stay running and rev up. Its not backfiring through the intake anymore like it was before and revs up pretty smooth so i seemed to have corrected half of the problem some how, now if i could just keep the thing running on its own then we would be ok. No I have not tried to drive it yet, I still need to make a gas pedal for the thing and then i can try to take it around the block
