Questionhello i have a 02 chry sebring this is my 4th time trying to put in the timing chain im running out of options i lined all the marks small chain i did the tdc, everything nothing works and i went thou the book. when i tryed to start it it back fired is there any way i can get it detailed for timing chain setp by step prinary secondary all of it thank you for the help

INSTALLATION - TIMING CHAIN
Inspect all sprockets and chain guides. Replace if worn.
For crankshaft sprocket installation procedures (Refer to 9 - ENGINE/ENGINE BLOCK/CRANKSHAFT - INSTALLATION).
If removed, install right and left side short chain guides (TIMING DRIVE SYSTEM - PRIMARY). Tighten attaching bolts to 28 N·m (250 in. lbs.).
Align crankshaft sprocket timing mark to the mark on oil pump housing (TIMING CHAIN ALIGNMENT MARKS - PRIMARY).
NOTE: Lubricate timing chain and guides with engine oil before installation.
Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links (TIMING CHAIN ALIGNMENT MARKS - PRIMARY).
Lower the primary chain with left side sprocket through the left cylinder head opening.
NOTE: The camshaft sprockets can be allowed to float on the camshaft hub during installation.
Loosely position left side camshaft sprocket over camshaft hub.
Align timing (plated) link to the crankshaft sprocket timing mark (TIMING CHAIN ALIGNMENT MARKS - PRIMARY).
Position primary chain onto water pump drive sprocket.
Align right camshaft sprocket timing mark to the timing (plated) link on the timing chain (TIMING CHAIN ALIGNMENT MARKS - PRIMARY) and loosely position over camshaft hub.
Verify that all chain timing (plated) links are properly aligned to the timing marks on all sprockets (TIMING CHAIN ALIGNMENT MARKS - PRIMARY).
Install left side lower chain guide and tensioner arm (TIMING DRIVE SYSTEM - PRIMARY). Tighten attaching bolts to 28 N·m (250 in. lbs.).
NOTE: Inspect O-ring on chain guide access plugs before installing. Replace O-ring as necessary.
Install chain guide access plugs to cylinder heads (TIMING DRIVE SYSTEM - PRIMARY). Tighten plugs to 20 N·m (15 ft. lbs.).
NOTE: To reset the primary timing chain tensioner, engine oil will first need to be purged from the tensioner (TIMING CHAIN TENSIONER - OIL PURGING).
Purge oil from timing chain tensioner using the following procedure:
Place the check ball end of tensioner into the shallow end of Special Tool 8186 (TIMING CHAIN TENSIONER - OIL PURGING).
Using hand pressure, slowly depress tensioner until oil is purged from tensioner (TIMING CHAIN TENSIONER - OIL PURGING).
Reset timing chain tensioner using the following procedure:
Position cylinder plunger into the deeper end of Special Tool 8186 (TIMING CHAIN TENSIONER - RESETTING).
Apply a downward force until tensioner is reset (TIMING CHAIN TENSIONER - RESETTING).
NOTE: If oil was not first purged from the tensioner, use slight finger pressure to assist the center arm pin of Special Tool 8186 to unseat the tensioner's check ball.
CAUTION: Ensure the tensioner is properly reset. The tensioner body must bottom against the top edge of Special Tool 8186. Failure to properly perform the resetting procedure may cause tensioner jamming.
Install the reset chain tensioner into the right cylinder head (PRIMARY TIMING CHAIN TENSIONER).
Position tensioner retaining plate and tighten bolts to 12 N·m (105 in. lbs.) (PRIMARY TIMING CHAIN TENSIONER).
Starting at the right cylinder bank, first position the camshaft damper (if equipped) on camshaft hub, then insert a 3/8” square drive extension with a breaker bar into intake camshaft drive hub. Rotate camshaft until the camshaft hub aligns to the camshaft sprocket and damper attaching holes. Install the sprocket attaching bolts and tighten to 28 N·m (250 in. lbs.) (TIMING DRIVE SYSTEM - PRIMARY).
Turn the left side camshaft by inserting a 3/8” square drive extension with a breaker bar into intake camshaft drive hub and rotate camshaft until the sprocket attaching bolts can be installed. Tighten sprocket bolts to 28 N·m (250 in. lbs.) (TIMING DRIVE SYSTEM - PRIMARY).
Rotate engine slightly clockwise to remove timing chain slack, if necessary.
Activate the timing chain tensioner by using a flat bladed pry tool to gently pry tensioner arm towards the tensioner slightly (TIMING CHAIN TENSIONER ACTIVATING). Then release the tensioner arm. Verify the tensioner is activated (extends).
Install power steering pump and bracket assembly.
Install camshaft position sensor and connect electrical connector.
Install the timing chain cover, crankshaft vibration damper, and cylinder head covers. (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) - INSTALLATION) (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - INSTALLATION) (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - INSTALLATION)
Install upper intake manifold. (Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANIFOLD - INSTALLATION)
NOTE: After installation of a reset tensioner, engine noise will occur after initial start-up. This noise will normally disappear within 5–10 seconds.
Fill cooling system (Refer to 7 - COOLING/ENGINE - STANDARD PROCEDURE).
Connect negative battery cable.
