The battery strap is one, and the strap that goes to the trans is also grounded there. There is also a wire gang coming from the injectors that ground there too......but you have injectors spraying, so maybe it's a non-issue. Spark, fuel, compression, and the right timing - what's missing? There was...

Two easy things to check for a D-jet no start - the ground gang at the battery tray has to have good contact, or it will not start. The other thing is to set the points with a dwell meter - 50 degrees is where you want to be. http://img.photobucket.com/albums/v226/dougsaab/dwellmeter.jpg
