2006 jeep liberty timing chain

[star2525]

when the chain gets loose the CMP sees that , and compared to CKP knows it bounces.
a loose chain makes noise too (odd)
if not the CMP may be bad only.
most shops would replace the CMP first. or pull the valve cover off and jog the cranks shaft and view the chain action to see if it is loose.
the problem is that the chain tension-er can fail. and only it is bad, then latter, cause chain to stretch.
so if CMP swap out fails to fix cmp errors (0016) then the whole chain is replaced and hydr. tension-er, and is expensive parts and lots of  labor time, 6 hours at least. the FSM shows the steps, it is huge.

Only had Jeep running for the last week and half. When I try to start it, I am turning key on several times and having to accelerate in order to get it started. Also notice sometimes I get nothing at key on, no noise, almost like how a starter goes bad.

I know you,  star2525 from far back as 2007. welcome back, (i remember your hard to drive on drive way.... rocky! )
welcome back,  I see you emailed me, that is ok too.
ok 2006 jeep liberty,  3.7L (I have 2 jeeps with your engine, one is wrangler one is grandcherokee
I have the full books and all 3 jeeps, full FSm


is this Jeep you have with automatic transmission?
if yes use both park or neutral to crank start it.
to crank in neutral  you step on brake key on and move the selector from park to neutral then crank  or the shifter is locked.
this trick uses fresh switch contacts in the PRNDL switch box,  of the selector. 


to cranks over ok, but wont start and wants more air, using accelerator means it wants to flood, and your trick adds more air and it starts.

keep the battery charged, clean lugs.
keep battery lugs clean.
if will not crank, move the gear selector back and forth  a few times, and even wiggle it cranking can fix it.
or wiggle the key to at start turn far right CW clock wise the key and jiggle it a bit,. this too can wake up its contacts.
these are all tricks not cures ,just not get stuck somewhere..  just keep foot on brake during all this .

It is automatic transmission. Battery has been checked out while vehicle is running. Interstate Battery. Good condition, new.

Have not tried starting in neutral. Ignition also has some slop to it as well.

Will try starting it tomorrow afternoon. Have errands in morning to do and using Sidekick to do errands
