Durring my rebuild I discovered that the same ground strap had not been re-installed but we continued on and made note of it. When we attempted to start the truck upon completion the computer did what kevin described "went bananas". I simply went to Sanels, purchased a longer strap and found an alternate root to ground to. That solved that issue.

I also had a ping which was described to me as a timing knock. I did what JLemond suggested to you here and adjusted the timing. That problem too is solved.

Just had to put my $1.50 in cuz you are referring to the same ground strap that I dealt with and my symptoms were quite different than yours.

Hope you figure this out phil...good luck.
