I wouldn't do that given the complexity of electronic modules an data bus communication networks on this vehicle . Disconnecting batteries can cause modules to go to sleep an not wake back up . The ignition switch is an input to the BCM - body control module , the BCM turns on relays powering up systems on the vehicle . The BCM executes the high power mode by grounding the controlled power relay coil control circuit of the CONTROLLED POWER relay whenever the BCM is awake. This circuit also is grounded for 15 minutes after you turn the ignition switch to the LOCK position in order to obtain the RAP function. After 15 minutes elapse, the BCM enter a sleepstate and transitions to the low power mode. The components under controlled power then receive any necessary voltage from the battery positive voltage circuit of the BCM. If the BCM is in the low power mode, and the BCM detects that the current exceeds approximately 2 amperes, the BCM wakes up and re-enters the high power mode. If the vehicle remains inactive with the ignition in the LOCK position and without any BCM wake-ups for a period of 3 days, the BCM deactivates the low power mode. The following components are under controlled power: There are probably DTC'S - diagnostic trouble codes stored in the BCM . A simple code reader can not read these , an has nothing to do with the check engine light . Battery Disconnect or Replacement Problems You may have been lucky so far disconnecting the battery .

Hi Jason Not much info to go on from your question. The simplest way to disconnect a Car Battery is by using a special battery terminal switch. This is a brass bar that attaches directly to the battery terminal and all the connecting wires go on the other end. The Knob on the middle is turned to isolate the battery. Hope this Helps. http://www.ebay.com.au/itm/141964353616?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT http://www.ebay.com.au/itm/Auto-Car-Motorcycle-Cut-Off-Switch-Side-Post-Battery-Master-Disconnect-Isolator-/391121153851?hash=item5b10a32f3b:g:iSMAAOSwLVZVtfhG

You need the remote and this will stop happening. Your key sensor is defective, use the passenger door.

The security system thinks someone is trying to steal the car and is disabling the car.

Check battery voltage should be around 13 volts if not charge it.

Could be a bad TPS - throttle position sensor , Videos on you tube on testing TPS sensor . In fact i would say that it is a real good possibility the TPS is bad .

It is bolted to the outside of the transmission.

How long has it been since it had a new fuel filter?

Fuel filter should be just in front of the fuel tank. There is also a filter sock in the tank on the fuel pump. Regulator should be at the engine near the fire wall usually in the fuel line. There should be a Schrader valve (like a tire valve) with a green cap on it this is where you connect a pressure gauge . It is between the engine and the regulator.

Check fuel pressure. If weak then either fuel pump or filter need replacing.

Due to the age I can only offer a generic solution. Please follow the link. how to replace power window motor part1

If u didnt do before servicing do so. Now. Unhook tbe negative battery cable for 2 to 3 min before hooking back up to clear the error in the system from rhw keep alive memory
