Scotty,
I have a 2018 Silverado with the 5.3 and 45,000 miles. It has no aftermarket parts. First noticed a problem when I tried to use the remote start system, and the truck failed to start. I started it with the key inside the cab and the truck shook violently, Idling rough with audible patterned knocking sounds. Engine power reduced’’ appeared on dash along with the check engine light. Checked the oil and it was good. I turned the truck off and then restarted it, and it ran normally but the check engine light was still displayed. Hooked the scan tool up and Code P2101 was found, which called for a cleaning of the throttle body. Looked at throttle body assembly and discovered carbon buildup. Wiring harness was intact. Truck intermittently would not start. The key would have to be turned multiple times for it to start. It didn’t try to turn over, onto a click was heard on the failed startups. After a day when the key was turned only a click was heard and it wouldn’t start at all. It’s under warranty so I had it towed to the dealer. They looked at it and said only the starter was bad. What do you think?
Thanks,
DOC
Sounds like a stater issue to me too. Hopefully the dealer also cleaned the throttle body, if not, do it yourself. One more thing: your remote starter key fob or receiver on the vehicle might be faulty too.
Yaser,
They finally called me today and said they confirmed it was the starter and mass air flow sensor, which would cost about 1200 bucks. I’m going to take it off their hands and replace the starter myself. Couldn’t find one at the pick and pull. Any brands you would recommend from the auto parts stores?
For the starter, go to Autozone and buy one with lifetime warranty. Ask them what is the best brand they got. For the MAF sensor, buy an OEM one and install it.
Sounds good I’ll do that. Thanks for your help
How are you trying to remote start the truck? On the fob you have to hit the lock button once, then the remote start button on the fob and hold it until it starts. (and be in range). When I got my 2017 Silverado 4 years ago, I was doing it wrong, then read the owners manual, works like a champ.
Yeah looks like it was just the starter and the mass air flow sensor which they want 1200 to put in. No thanks. Thanks for the help though
Yeah...$1200...um NO flippin' way !!! What's that like 30 minutes of actual work and the parts are not that expensive. That's why I hate stealerships.
