Welcome to the forum, my info says the crank relay is located under hood junction box (top). There is also, a pcm/crank fuse, left instrument panel junction block, use a test light on that fuse circuit, goes hot with key in start position. That voltage is crank request to the pcm, then the pcm should ground the coil side of crank relay.

See the guide below, it will help

2001 Monte Carlo with 124000 miles. First the amp guage quit working. At the same time the door lock switches quit, and the compressor on the air conditioner quit. The car would start and run fine but the check engine and the security lght would flash on dash. I checked the alternator and it was working fine. The parts store said there was a bad cell in the battery, replaced it now it will not start at all. The system lights but it will not turn over at all. Does anyone have any suggestions?

Full battery charge. Double checked fuses. Starter is ok.
Is there a way to reset the security system? I unhooked the battery for about an hour to see if the system might reset.
When I Hooked it back up nothing changed but I did notice the
check engine light is now on so I figure There might be codes in the computer. I don't have access to a reader till late next week.

Last night my 01 Chevy Monte Carlo SS would not crank after I shut it off. It has done this in the past and usualy I can un hook the battery and hook it back up and it would reset itself and then crank. That didnt work this time. Now when I try to crank it. It says low fuel and I have a full tank it also says service traction and car soon, the only dail on the dash board that regesters is the battery. The temp, fuel and oil stick will not move and when I go to turn it on I get nothing not a sound. Please help!

You have to be sure the battery has a full charge and the connections are all clean and tight. My next thought is the security system.

Thanks, but the battery is connected tight because all my lights are on. What could be wrong with the security system? Sometimes my blinkers work when they want to and my radio locks up.

Tried what you sent and the indicator light does not go off. Does the car need to be running to check for codes? Do you have any more ideas?

Just because some of the dash lites come on, doesn't mean the battery has a full charge.

Is the security lite on or flashing, when you try to start?

It doesnt need to be running to read codes. You could check for spark actual fuel pressure and for injector pluse.

I know it's been awhile but I finally got it running so I thought I would let you know what it was. I had it towed to an electrical shop. They had experience with this problem before and within 1 hour I was told it was the Body Control Module located under the dash. The module controls all the inner workings of the car. It Cost me $593.00. They had it ready the next day. Not bad considering a dealership would have probably cost twice as much. Pass this information on to all who might need it and thanks for your help.

You can try the 30 minute relearn procedure. When you try to start, leave the key on, watch the security lite, see if it goes off after about 10 minutes, if it does, turn key off for 5 seconds. Repeat the procedure twice more for a total of thirty minutes. If it is going to work, if should work on next key cycle.

You need to check for applicable codes. To check codes, yourself, at the least, you need an obd2 code reader.

This is a case where unless you know how to do some basic electrical testing you are better off getting a mechanic involved. The generator doesn't even do anything until the engine is running. GM does have a huge problem with theirs but if a jump-start won't help, forget the generator for now. Spark plugs are part of what makes the engine run. You haven't even gotten that far yet if it doesn't crank with the starter.

You can start the diagnosis yourself by visually inspecting all of the battery cable connections and making sure they're clean and tight. That includes where the two cables are bolted to the battery, where the black one is bolted to the engine, and the red one is bolted to the starter. If you use any metal wrench or other tool on the red one, don't let that tool touch anything else metal at the same time. You'll have serious sparks.

Also follow the two smaller battery wires and check those connections. The black negative one bolts to the sheet metal of the body and typically the red positive one bolts to the under-hood fuse box. That last one causes a lot of loose intermittent connections.
