SO i installed my motor today but and when i turn it over it tries to fire but doesnt fully start. It just keeps turning over

One probleme may be a ground wire that goes somewhere.

Its on the driver side of the truck and i somehow missed it and im not sure where it goes. If i remember right it goes to the back of the block but not sure where it connects(heads,block,trans???)

Any info would be great

 

Front or back of the engine? There are two that go to a bolt up by the P/S pump. One of which is the injector harness...... I think the other is a battery ground, or, something else over on that side of the truck.
