So my pops has a 07 Chevy Silverado with a v6. 41,xxx miles. Starts up and runs just fine, then go to start it later and it won't turn over, and the radio don't work or the fuel/temp gauge, but the rest of the cluster lights up. If you unplug the fuse box under the dash for 5 min or so and plug it back in it will start up and run fine after a couple of min the radio will shut off but the truck still runs. Once you shut it off it won't fire back up unless you unplug the fuse box.

If its still got any semblance of a warranty, make it a dealership's problem.

If not, does the insurance cover fire damage?

highroller54 · « **Reply #4 on:** November 05, 2013, 04:30:24 PM »

Well I've done a few ignition switches for similar problems except the fuse box part

Its in Alaska in the bush. Would need a 6 day trip to make it to the dealer....lol

Roller did it make half the gauges not work but power up the idiot lights still?

Thats actually an interesting thought. I had a Vw New beetle that one side of the ign switch shit out and half of the car wouldnt work, alot of the acc. and shit. I just tied into the good leg with a relay and a diode worked magic car is still on the road.

Yes, or kill power to the trans, or other things depending on which contacts burn out.

Joseph Davis · « **Reply #8 on:** November 06, 2013, 12:50:07 PM »

ECU drives half the gauges on the cluster. Loss of connection on the CANbus will do that... if the truck cluster displays a bunch of dashes in place of odometer readout, suspect ECU/power to ECU/something shutting down CANbus (radio).

Joseph Davis · « **Reply #9 on:** November 06, 2013, 12:51:49 PM »

BTW, I do not know if the tach/speedo/gas gauge/etc are actually driven across CAN, or have dedicated wires like earlier vehicles. Just a guess, as that would be how I dod things.

highroller54 · « **Reply #10 on:** November 06, 2013, 04:24:41 PM »

Would be nice to have the codes, those clusters are pos to.

ratcityrex · « **Reply #11 on:** November 06, 2013, 06:50:17 PM »

I will pass the info along. Ill let u guys know what's up.

ratcityrex · « **Reply #12 on:** November 06, 2013, 07:16:03 PM »

So more info.......

Left it running in the driveway for about 20 min (45* outside) came out and it was running hot 230*ish as soon as he started driving temp dropped to normal. But its bucking while driving and pinging. When he shuts it off it diesels.

i know, i was being a dick as i have never seen a fuel injected auto run on unless its got a slobbery injectorator and even then............

highroller54 · « **Reply #16 on:** November 06, 2013, 10:38:41 PM »

is there anyway he can get me codes? BUT clear them first since he has introduced false ones im sure. ecm, cluster, trans, abs, (all)

ratcityrex · « **Reply #17 on:** November 07, 2013, 02:17:22 PM »

He has a scan tool, and he said there is no codes. Its some high dollar scan tool that the city uses but he said it has no codes, but new problems keep poping up so ill see if he can run a scan on it again.

highroller54 · « **Reply #18 on:** November 07, 2013, 03:13:01 PM »

needs to be able to scan more then just the "engine"

fearsomedan · « **Reply #19 on:** November 07, 2013, 10:06:01 PM »

my dad has an 05 silverado with a v8 that had the same gauge and radio symptoms you are describing. I ended up doing an ignition switch, the cylinder part not the electrical part. The way I figured it out was by jiggling the key while the truck was running. I pulled it apart it visually saw it coming apart. Have them visually check the cylinder and the electronic part for anything that is suspect.

ratcityrex · « **Reply #20 on:** November 08, 2013, 01:32:49 AM »

Will do. Ill pass it along.

Joseph Davis · « **Reply #21 on:** November 08, 2013, 04:55:40 PM »

Slobbery injector, Chad?

Sounds like the key kills the fuel pump, and not the ECU. Motor stumbles as fuel pressure goes away.

ratcityrex · « **Reply #23 on:** November 08, 2013, 05:03:46 PM »

Ok, so new stuff....... So he shuts the truck off and walks away. With no key In the ignition and the truck will start itself up and sit there and idle. He was able to get a code but it was p1682

ratcityrex · « **Reply #24 on:** November 08, 2013, 05:04:52 PM »

If it were me I would let it sit there and idle untill it caught fire and collected insurance money.

So the "genesis" code reader that they are using to read codes is saying the the bcm is fucked. Body control? Truck won't even start now.

Ntrain2k · « **Reply #28 on:** November 16, 2013, 10:23:42 PM »

Yep, body control module. Runs the gauges, etc.

If you get another one either the ECM or the BCM itself will have to be reprogrammed for the truck, IIRC.

Joseph Davis · « **Reply #29 on:** November 19, 2013, 03:25:43 AM »

BCMs die a lot. I never really see that end of things. *shrug*
