My question is if changed the crank sensor it should start with no problem right

What is your question?

Today I went to get gas then I tried to turn it back in but it wouldnt start up. So I changed the crank sensor on it then I tried again but it still would not turn over... so my question is if I changed the crank sensor should it start with no problem? So guys I need a tip here because I need my van back on the road for me and my family because that's our main van thanks.
