Low or bad battery can cause problem your describing. I've also seen this type problem with faulty battery cable fist make sure battery is fully charged
Check at the connections at the battery and clean ...resistance in circuit ..visual inspection of yhe circuit ..requires a wiring map.. check relays for being hot by touch and corrosion or water.. may be a body control module fault bcm
How about your batt power? The battery may be way down on voltage and your problem starts here.
Check the battery voltage
I think you could use this manual method instead.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from. reliable-store

We had the same problem. It was an expensive fix--there apparently was a problem with the onboard computer that would periodically lock out the ignition circuit. Felt just like a bad starter solenoid--but the part cost $800, plus labor, to replace. Ouch.

There may not be any other way to fix it except to replace your instrument panel. That's where your immobilizer is located. Or you could try this:
Try cold-booting the car. Remove both battery cables from the battery.
Short the battery cables together (away from the battery) for about 15
seconds. Reconnect the battery. No guarantees - I found this info at tdiclub.com.
SOURCE: immobilizer
If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.

I assume you've checked all connections from the battery and starter to make sure they are clean and tight. It is a little weird that you do not have trouble starting in neutral yet you get a clicking sound in park. My first thought would be the neutral safety switch on the transmission but you shouldn't even get a click in park if that is bad.
One possibility is the contacts in your starter have worn down and are causing too more resistance (explains the clicking). At the back of your starter is a metal cover that is held on by three tiny bolts (6mm). Disconnect the battery first! (You might have to remove the starter to get to this part) Remove this cover and pull out the plunger assembly. Underneath are two brass plates. Compare one plate to the other. If one is noticeably thinner then it could be the cause of the clicking. You will even see a round groove in the plate. You can buy the plunger and contacts from this website: http://www.nationsautoelectric.com/densoparts.html or you can opt to get a starter from your friendly auto parts store. The first picture shows the bad contact on the left. Notice the groove, the metal has become really thin there. This picture shows a pitted plunger assembly. Always good to replace it too.This picture shows all the new parts installed.
Is it even clicking? If not, skip to "no click, no jump" section of my post below. You do not have a start relay. Make sure your alarm system is not tripped and try giggling the shifter or shifting to neutral while holding the key to start. If these things don't work, try test 2 under the "solenoid clicks" section of the post. If your starter passes this test, the problem is probably in the ignition switch or the interlock switch/relay. let me know if you get stuck.
Please see my tip at http://www.fixya.com/cars/r6222268-engine_doesnt_crank_turn_over . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
