2002 Jeep Liberty Prolonged Cranking problem

I have a 2002 Jeep Liberty 3.7L, the problem i have is that when i go start the car, it takes longer than normal to crank over. I have already changed the Spark plugs, battery, crank and camshaft sensor, cleaned the throttle out, and had the fuel pump buellitin done. the place that i took it too said that i have good fuel pressure now. has anyone had this problem, or might have any ideas what might be wrong with it? the only thing i noticed when i changed the spark blugs is that the one that went into #1 Cylinder was browner than the other ones and smelled like fuel a little bit. Can anyone HELP!

Fuel pump: The engine may crank several seconds before starting due to loss of fuel pressure caused by a bad check valve in the fuel pump assembly. (2002 models)

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

Try a battery with more cranking amps cannot hurt. If it is a diesel have an engine heater put on, there are also glow plugs which preheat the combustion chamber on a diesel try to cycle the glow plugs twice before cranking. a battery warmer is also a good idea and thinner oil for the cold season.

00.6v at the fuel pump

are you reading the meter right ?, less that 1 volt?
did you crank the engine and read,many car dont start the pump unit cranked.
it must be 12v or 11v if very cold and bettery volts sag a bit (1v) cranking. that is how you do this.
on some jeeps (i dont do liberty) the ASD works like this.
the 2 second rule.
TAKES 2 people to test a JEEP.
not 1.
one to crank and one to measure.
the PCM allows 2 seconds. of full spark and injections
if it sees errors,. it kills every thing, spark and fuel.
its jeep.

While trying to start my 2002 jeep liberty limited edition 2wd 3.7l engine I only get a click, after any number of clicks it finally starts.

It sounds like you need a new battery. If it's a 2002, then it's probably on it's second battery already and due for a new one. The clicking is the starter solenoid trying to engage the starter with the flywheel. If the battery can't supply enough "cold cranking amps" or "power", then it makes that clicking noise.
