Background: I had my Tilt/Trim relay/selinoid start to go bad. It would not work after motor warmed up. I couldn't remove it because the two bolts that hold it wouldnt come out so I thought I would take the selenoid apart and clean contacts inside. I must have put something back together wrong cause when I hooked it back up and switched the battery on I got smoke. Quickly turned battery off. I removed selenoid by cutting the back of the plastic mounting bolt holders and installed a new selenoid tilt/trim works now.

Problem: won't start. Good battery, fuel pump working good pressure at schrader valve. I have a weak spark on all plugs (tested at night and its not bright & blue, but weak and yellow.

What did I do? What could I have done when I tried to fix selenoid? Fuses are in tact. I was thinking bad ground, but I looked and couldn't find any wires thy I might have burned up.

Update....
I was able to get it started on muffs and thought maybe checking ground wires fixed the problem. However now I have a puddle of unburnt fuel/oil on the ground. Still weak spark on all 6 cylinders.
