Hi, my name is\*\*\*\*\* to justanswer. I will be assisting you with your question today. Is the gear shifter going completely into park position? **\*\*As far as phone calls, If you didn't request it, it is most likely the Website prompting you, not me. A Live Call is a "Premium Service" and will cost more money. I prefer communicating via this site, but in some cases a phone call may be recommended.\*\***

it is in park. And we tried changing the brake fuse also
Automotive Expert
The [engine](/topics-engine-chevy/) will shut off, but the key cannot be removed, correct?

No the engine will not turn off. My truck is stuck on running
Automotive Expert
Did you try putting transmission in neutral and shutting off engine?

No. So I put it in N and turn off my keyI just tried it. The key won't turn still
Automotive Expert
Can you locate the fuel pump fuse in the underhood fuse block and remove it? This will at least shut off the engine. Look for the PCM B fuse 20amp. This controls the fuel pump relay.

Ok. And after I do that to turn off the truck I'll have to have a mechanic come and fix it
Automotive Expert
After the truck shuts down, I would reinstall the fuse and try disconnecting the battery for a few minutes and then try turning the key. It may unlock for you.

Ok. My husband is looking for that fuse now
Automotive Expert
Okay, good!

The fuse is pulled and outHe is disconnecting the battery now
Automotive Expert
Did the truck shut down?

the truck is off after taking off the fuse. He is working on the battery nowHow long do we wait before putting the fuse in?Batter is unhooked
Automotive Expert
3-5 minutes should be fine.

Ok. Then put the fuse in 1st? Or the battery 1st? And after we put the 1st one in do we wait a bit before we do the 2nd one
Automotive Expert
Reinstall the fuse first and then reconnect the battery.

Ok fuse is in and he is connecting the battery nowThe truck started upThe ABS and parking brake light are off now, but the key won't turn
Automotive Expert
Did the truck start up on its own without you turning the key?

it started up on it's ownthat ABS and parking brake lights just turned back on
Automotive Expert
I would repeat what you did to shut the truck off. It sounds like the ignition switch has failed internally and will need replacing.

Ok so we will pull the fuse and battery again and try to get a mechanic to look at it tomorrow then, right?
Automotive Expert
Yes, exactly. That way he can also diagnose the abs/brake light as well.

Ok. Thanks
Automotive Expert
You are very welcome! Best of luck with your vehicle, and thanks for using justanswer.
