2006 jeep liberty timing chain

[fixkick]

starter relay is in the PDC box under hood, power distribution box.
1. Remove PDC cover (3). from box 2.  PCS is just in front of  main battery.
2. Remove relay from PDC. (the lid on the PCD shows where it is)

this car  is modern and more unique:
here is how the starter spins, (its not just wires like on a suzuki old)

you turn the key, to ST (start)
the PCM sees that and if SKIM is happy (IMMO) then the PCM not you cranks the engine
the PCM looks a PRNDL switch in the A/T box, and sees for sure the transmission is not in gear. (logic)
then the PCM grounds (using  transistor) the START RELAY. dark orange wire on PCM does that. if not the Starter will be dead.
this is for you or your MECH, that has no proper book.
