ISUZU TROOPER WATER PUMP PROBLEM

1988 Isuzu Trooper • 130,000 miles

I have recently replaced my water pump on my 88 isuzu tropper 2 pick up truck "OH MY GOD" I wont start. I finally got it back together and past my pressure test. But I beleive because its running like crap I may have messed the timing up. It starts up and makes a knocking noise and all of the dash warning lights light up then it dies if I dont give it gas. Question is Could it be something else making it act like that? Also when I turned it over by hand, after I installed the water pump it would be sooth about 3/4 of the way around then it would get a little tougher to turn about 1/4 of the way around then sooth again. IS this normal? Thanks alot
