Question about 1997 GMC Savana

1 Answer

I have a 1998 GMC Savana Conversion van with a push button battery saver on the dash board. When I turn the ignition key on it immediately kicks all the power off line. The engine does not crank, no clicking Nothing. I can hit the batter saver button again and the clock ligh comes back on etc. but again when I turn the key it kicks off line. I've check the battery and connections are all are fine. In a previous repair 6 months ago I had the ECM computer replaced and the security key card mechanism under the dash removed. Any suggestions on this latest glitch?

I had this same problem. A mechanic said it wasn't the switch, but that I needed to replace all kinds of other stuff. I pulled the switch out and discovered that it had literally disintegrated on the inside, and was shorting out the battery (not saving it). I'm referring to the "switch" under the hood, not the push-button on the dash.
You can bypass it by joining the two power connectors together, and ignoring ALL the other wires. I simply used a nut & bolt to join the wires, as it would've required replacing a fusible link to replace the entire cable. I then insulated the connection, to keep it from touching any body ground locations.

Check your ignition key, if its excessively worn , have a new one cut and see if the problem persists. If ignition tumblers are not set correctly it wont start, even if it does turn the lock cylinder.

Someone attempted to steal my 1998 Savana Conversion van, I had the steering column replaced and now it still won't stay started, and a security light is on the dash board. Is there a fuel pump reset...


Hi, the security system has to learn the new key resistor in the new column. If you try to start it, leave the key on for 10 mins, the security light will go off. Turn the key off, try to start it again, and release the key. The light will come back on again. Wait another 10 mins, intill the light goes out again. (leaving the key on). This has to be done 3 times total of 30 mins. When the light goes out a 3rd time, the vehicle should start, and run. Remember to turn off the headlamps, heater, radio, etc... as they consume power, and you do not want to kill the battery. Good luck...Coop

It just clicks when I go to start the engine


Check your battery connection's, if when it clicks one time do the lights go off?Then more then likely bad battery connection.With light switch on move battery connection if lights come on you found your problem.
