So Saturday I drove my truck to my shop unhooked my batterys and pulled my injectors to clean them. I put everything back together just the way it was and bleed my fuel lines now my truck will not start and it's throwing a p1688 code injection pump failure I didn't do anything with the injection pump and didn't even unhook it need help can't figure out what's wrong

 

Try clearing the code and see what happens. Check connections on the VP. Clean battery terminals.

 

I tried all that and everything else I can think of I'm to the point where I just think my vp took a crap on me which is unfortunate but that's the only explanation I can come up with
