timing issues

[madmechanic13]

so hear it is i have a 97 ford ranger with a 2.3 liter motor and i recently blew a head gasket....that said i just decided while i have everything apart i might as well do all the good stuff to it plug wires belts etc. well that being said i got all that on there and put it all back together and now i cant get the thing timed i know i know line up the marks how hard is it well there is a inch long piece broke out of my crank pully not were the belt rides but it just so happens to be the spot with the timing mark go figure right so i am ordering a new one of those cause no matter what i do ie facing the keyway straight up to the top of the motor and lining up the marks on the cam and the other pulley maybe a smog pump or something? that dont work tries to fire so i move the cam one tooth at a time in each direction till it runs worse then i go back the other direction i can get it to almost start but it wont well then i go back to original and rotate cam one full time thinking maybe it was 180 degrees out of time and repeat steps of moving one tooth at a time still dont work i am at the point were i am wondering if i moved that aluminum ring(the one the cps reads off) when i put the prybar in it to keep pulley from moving while i was taking bolt out of crank and that may be why it isnt firing i dont know i am just out of ideas....owe and on top of the whole thing i get in to push the clutch and break in and my pedals brake off the aluminum bracket so i am just stressed to the max any help or suggestions would be appreciated
thanks again fellas or fellats which ever may apply

The keyway on the crankshaft will be straight up. This puts the #1 piston at top dead center.

There are three white marks on the rear cover just under the camshaft sprocket. There is a triangle on one of the cam sprocket teeth. This mark lines up with the center of the three white marks.

The other sprocket is not an air pump. It must be aligned. On one of the teeth there will be a diamond. This diamond lines up with a diamond on the rear cover. It will also be pointing up.

Don't let anything move when you install the belt. When you get it installed and tensioned, turn the engine clockwise(standing infront of the engine. This will be normal rotation) by hand a couple of engine revolutions. Re-check the marks. You may have to re-set them if all the slack wasn't out of the belt.

Do this unitll the marks stay lined up under belt tension.

Don't turn the engine the wrong way as it will jump teeth on the crankshaft sprocket, and you have to start over again. shady

It is for the auxilary shaft which drives the oil pump and camshaft position sensor. This sensor detects #1 cylinder so the coils and fuel injectors can be properly fired. That is why it needs to be properly timed. shady

The bung behind the ps pump is also where the dizzy would have dropped in and intermeshed with that shaft before DIS came along.
