Removed aftermarket remote start now wont start?

Hello, will the truck stay running if the gas pedal is kept depressed? Otherwise then yes you may be on the right track regarding the anti-theft fuel shut-off capability. I have also seen some retro-fitments leave harnesses unplugged that give reference to the engine harness side.

No nomatter what it pops off then just dies right away. I just found a green wire coming threw firewall that when I use test light it makes my rpm tack move when key is in the on position but idk where to connect it to.

If you bought a new key for the truck, it will likely need to be programmed. Have you tried the stock programming solution for the truck?

Here is an example:

Key Chip Programming (Passlock):
Step 1: Insert the new key and attempt to start the engine; it will likely stall.
Step 2: Leave the key in the "ON" position (do not remove it) and observe the SECURITY light. It should stay on or flash.
Step 3: Wait 10 minutes until the security light goes off.
Step 4: Turn the ignition to "OFF" for 5-10 seconds.
Step 5: Repeat steps 1–4 two more times (total of 3 cycles/30 minutes).
Step 6: On the fourth attempt, the truck should start.

Key Fob Remote Programming:
If you are trying to program the keyless entry remote (fob), use this method:
Close all doors and insert the key.
Press and hold the UNLOCK button on the driver’s side door panel.
Turn the ignition ON, OFF, ON, OFF (do not crank the engine).
Release the UNLOCK button; the doors will lock and unlock.
Hold LOCK and UNLOCK on the fob simultaneously for 15-30 seconds until the doors cycle again.
Turn the ignition to ON to exit.

There is no security light on when key is turned to the on position and its the original key. I've disconnected the battery for a day n hooked it back up n same shit cranks n pops off n then dies right away.

Okay, do you have a scan tool? There is a chance the scan tool will pick up on an electrical code relating to the fuel system or computer.
