Timing Chain

HI I OWN A 2002 RXV AND IT WON'T START LAST TIME I HAD JUST CHANGED PLUGS SO I CHANGED BACK AND IT WORKED BUT THIS TIME IT SEEMS LIKE THE TIMING IS OUT AS IT DID LAST TIME IT WILL START WITH A PUSH. ANYWAY DOES ANYONE HAVE DIAGRAMS OF TIMING BELT AND INSTRUCTIONS ON HOW TO CHANGE
THANKS
