Are you using voltage sense or a tach wire? More than likely there is another ignition wire you need to power up.

Notes:
NOTE: For the 2002 Ram 2500/3500, refer to the 2001 techsoft sheet. NOTE: Chrysler vehicles that use a gray ignition key have an immobilizer system that needs to be bypassed when remote starting. Use DEI part number 555C or 555U. *1 Lock requires a negative trigger thru a 820 ohm resistor. Unlock requires a negative trigger thru a 330 ohm resistor. MUST use relays. *2 Parking lights require a negative trigger thru a 330 or 1.4K ohm resistor. Headlights require a negative trigger thru a 1.8K ohm resistor. There is a rest resistance on the wire, so MUST use a relay to isolate away from the switch. *3 The LF door trigger is tan, and the LR door is tan/orange or PURPLE / orange. These wires are in the driver kick panel. The RF door trigger is tan/red, and the RR door is tan / YELLOW. These wires are in the passenger kick panel. Use all wires and diode isolate each. See directfax document #1076 for wiring information. *4 This will also do door locks. Arm/lock is negative trigger thru a 2K ohm resistor. Disarm/unlock is negative trigger thru a 480 ohm resistor. Single pulse will do disarm without unlocking the doors. Unlock requires a double pulse. MUST use relays. *5 The PCM (Powertrain Control Module) is on the passenger side firewall. *6 The amplifier is located behind the glove box. *7 These wires may not be necessary for remote start.

i got the check engine light to go off by unhooking my battery for 20min. and then reconnected it, but the starter is still engaged when remote started

The RS is not programmed to the tach wire on the truck. It doesn't realize that the truck has started and is not letting go of the starter. What tach did you use ?
