Question about 1997 GMC Jimmy
I tried to start my Jimmy and when I inserted the key and turned it, no lights came on in the dashboard (airbag light, check engine, etc.) and the engine turns over but will not start. Headlights and interior lights still work, clock and CD etc. After trying over and over and over again for several minutes, the start-up warning lights will come on and the car will start right up. If I turn it off and try it again, usually the lights won't come on and I have to try over and over again to get it to restart. It's really annoying not knowing if and when the car will start, and when going to the store, I usually take a spare key and leave it running with the doors locked so I don't have to try to get it to start again.
Sounds like a bad ignition switch but could also be a bad connection to the ICP or just a plain old bad ICP (Instrument control panel). The ICP needs to be able to communicate with the ECM, Brake Control Module and the SDM (sensing and diagnostic module). If these can not "talk" to each other the vehicle will go into a lock out theft mode...assuming it has a factory VAT system. But I would bet on the ignition switch first...seen it many times.

Testimonial: "Thank you very much. It will be very helpful to have an idea when I talk to the shop of what it might be so I can compare costs and won't look stupid."
My 1997GMC Jimmy was having a hard time starting after a heavy rain and when it final kicked over it make a loud back fire noise so I shut it off immediately. So smoke or no strange smell. But I am afraid to try and start it again.

I actually just took mine out today on a 1998 Gmc Jimmy. Its kind of simple now that ive done it. There are four ten millimeter bolts holding the passenger module in. you will need to drop your glovebox down so it is upside down to see these. It is easier if you take it right off. just take a shop light and look at the bottom of the module you will see two silver bolts (the only two ten mm down there) take them out. Then if you look up underneath you will see another up at the top left. To get this out you can hand wrench it or you can use a mini impact with an ajustable extension. to get the next the easiest way I found was to take off the trim aroung your speedometer get in the drivers seat and there is another ten millimeter nut on the top right (right by the vent holes) take that out then you are unbolted. Without going into tons of details when you start doing it you will quickly realsie how to do it it just takes some patience. Dont forget to pull the fuse before you do anything its a 15 amp fuse second row 3rd up in the panel inside the car. Hope this helps
