Asked by Oct 20, 2010 at 10:39 PM about the 1998 GMC Jimmy 4 Dr SLT 4WD SUV

Question type: Maintenance & Repair

why does my jimmy start and shut off after about 3 seconds?Had jimmy running fine but the
starter give out i put another one on but wouldnt start.accendently took out security bypass for
the remote start. so i took out the the remote start and joined the wires back to orignal now the
jimmy only starts for maby 3 seconds and shuts off. the battery light stays on and the odometer
stays on with the key out. how would i reset the security? I think that might be the problem.

What is the security light doing on the dashboard - Have someone pull codes for the passlock system - should begin with a "B" We can help further after that

First of all I didnt read the ending ... IF the battery and other lights stay on with the key out the wiring is wrong .. now you computer has cleared its key code in the body control computer so it to shuts off as a security feature for the car. Wire it properly then take the original key it in the ignition. Turn the key to run but do not start the vehicle. Wait until the security light goes off and then remove the key from the ignition. Should be ready to go after you do two keys.

here is the reset, if this doesn't reset it u have a hard fault. PASSKEY LOCKOUT RESET ALL GM CARS 1999 AND UP 1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key
