Hi all just wondered if you could help me, I have just replaced the timing belt on my van but after putting it back together I have a problem

It just wont idle & there is alot of smoke. I think I might know what the problem i s but i am not sure. When I was lining everything up for TDC the pump was off by about half an inch so I undid the 3 bolts on the pulley & moved it slightly then tightened it back up Any help of where it should be?

Thanks
