1994 caravan 3.0 l v6 need help please...

ok so heres what happened.a few months ago i lost my timing belt while driving.Before i lost it the van drive fine.Replaced belt and everything seemed ok.drove it for a week or so and then one day it started sputtering and stalling.Acted like it wasnt getting any fuel.After we got it home we checked the fuel pump(working fine) changed the fuel filter (it was old so figured it couldnt hurt).Started up fine so we figured problem solved.It wasnt though.The van would run perfect until it warmed up then would start the sputtering and dying thing.You couldnt start it until it had cooled back down.In the last month we have changed the throttle position sensor,the pick up coil/ignition module,cleaned the throttle body,checked the egr valve and the MAP sensor to no avail.The van is throwing code 54 which i was told is the camshaft position sensor.According to the haynes and chiltons we dont have one on this engine.I was also told that maybe it was the crankshaft position sensor(again I supposedly dont have one on this engine) does anyone know if this engine does indeed have these sensors and if so where they are located.All I know is that according to autozone.com they sell a crankshaft position sensor for the van but i couldnt find a camshaft one on there.And now the van wont start anymore.We arent getting any spark to the coil at all.Please someone help me .I have four kids and no car to go anywhere so they are drinving me nuts lol.I really need to figure out if we can fix this thing soon.Thanks.

The camshaft position sensor is on the bell housing of the transmition on the 3.0L. If you ar going to take it out be very careful because it breaks off easily.
