2005 nissan titan remote start trouble

Hello Everyone, I am installing a Valet Model 561R Remote start on my father in-laws 2005 Nissan Titan XE. Now this is the base model of the Titans. It has no power windows, no power locks, no keyless entry or anything like that. The other models come standard with all these things. I''ve been searching and searching and can't seem to get anywhere with this. I got the remote start working but having a little problem. When i hit the remote start button, it starts up but dies out right away. I know some models of the Titan come standard with an immobilizer but I thought the base model XE didn't. I cant find info anywhere on it. If I put the key to "On" position and start the remote starter, it comes on and stays on. Or if the car is running, I can hit the remote start and take the key out. I've tried leaving the key in the off and acc position but just dies out. I set the Tach setting and even tried using the voltage setting instead of the Tach setting without change. So can anyone out there shed some light on this, i'd hate to buy a bypass and not need it. Also my father in-law had a key made at the hardware store and its a regular key nothing special, and it works fine without the factory key being in the car. I'm going crazy and would love some answers if you have them.  I'm looking for a hero.

I've triple checked the wiring, although the pink/white wire says it goes to "programmable output for accessory or ignition", then when you look up under the notes for it, it says "Connect this wire to the second ignition or accessory wire in the vehicle". Well i don't have a 2nd ignition hookup so i put it to the purple 2nd accessory line. I have the 2 red power lines hooked up to the green 12 Volt line, Pink wire goes to the BLACK/ red ignition line, Purple to brown starter line, orange to the red accessory line. I have the neutral safety switch grounded off. I have the brake switch hooked up. the parking lights are hooked up and flash when the remote start is working. I thought maybe i was wrong about it not having an immobilizer but my father in-law just keeps saying that the hardware store key works fine so i can only assume it doesnt have one. I do have a second starter wire that is lt. green that doesnt get hook to anything on the remote start.

I really appreciate all your help!

did you program the remote to treat the pink/white wire like an accessory? I think its defaulted to act as an igintion. it may be that because that wire is not dropping out durring remote start it wont stay running. are there 2 start wires in that vehicle?

Agreed you have a second starter wire that is light green. You must add a relay to this wire to energize it during the crank cycle...

do i just run a lead off of the purple wire of the remote start to the 2nd starter wire on the ignition harness which is lt. green. Right now the purple wire is on the brown starter wire and i don't have anything on the lt. green.

the purple wire is for (+) (30 AMP) OUTPUT TO STARTER CIRCUIT

it also has this connection for a 4 Pin Satellite Harness which I do not have hooked up. The options are as follows:

yes just run a lead off the purple wire and attach to the second starter green wire
