2006 liberty cranks but wont start


gas engine, not diesel.
its probably flooding, ever give it a 60k mile tune up, ever?
we check spark tips for flooding and dry,never do we guess at fuel pumps, ever. (pressure gauge is $20)
tips dry or soaking wet.
we check for spark , no gas engine car runs with no spark
so we check all cylinders for good spark
if spark is good and flooding (new spark plugs) we use
cranking wide open throttle wot. like the operators guide says.
start now? this cuts all injection, this magic PCM trick.

see scotty ,
1: compresson at spec, 2: spark good and timed. and 3: fueling last.

skip the silly ad.
note he says 2, but he ASSUMES compression is good. (oops)
but his tests are fast, and if it fails to start, see #1 above. ask

Changed the spark plugs to E3's about a day later the engine started to idle rough and now the check engine is on


Sounds like bad plug wires, and/or one or more wires may not have been clipped back on all the way and came off. Old plug wires do not like being disturbed.
With plug wires, its the age, not the miles. Spend the money for wires from a Jeep dealer. You'll thank me. Hope this helps.

I have the p0306 code showing for my 2004 3.7 liter V6 Jeep Liberty. There is a loud knocking/popping associated with this misfire. I have changed all of the spark plugs and the ignition coil for...


but not one ASE mechanic i bet. they get it right.
so 306 means must misfire.
or better, weak Combustion on #6
so did your mech check compression on #6?
seems not. or vacuum for bouncing, seems not.
that knocking, did he check that first. it must NOT knock.
that knock is serious and will get worse, Id not drive it.
not me, engines are expensive why make it worse?

Jeep engine is knocking


this engine has two knock sensors that plug in under hood back of manifold drivers side the sensors are located under intake manifold that needs to be removed if sensors or wireing is damaged a good mechanic can change one in about one hour or less

The Jeep comes with Platinum plugs from the factory.
And also a little secret-They are guarenteed from the manufacture for 1000,000 miles
Your Jeep should have Champion plugs in it.

2002 Jeep Liberty Prolonged Cranking problem


it sounds like your timing system is on its way out the belt probably has streched and is close to not working at all.when u turn your ignition and applies power to the starter for the vehicle to start the piston must be in the right position when the electrical current ignites the spark plug. if u smelled gas thats from fuel that didn't explode in the chamber from a misfire, the misfire is because the spark and the chamber position are not in sync
