Isuzu rodeo95 2.6L replaced water pump&now turns but wont start. did I mess up timing belt or is my engine ?

Question

engin shot? I had to take belts off to take out pump.

Answer 1

if engine ran before timing belt was removed for water pump replacement then timing is now off.

Answer 2

But did you take the timing belt off?  If you did, you may have lost engine timing.

Be really careful getting that correct - get it wrong and you could destroy the engine.  You might want to take it to the shop instead.
