Silverado No start issue....truck cranks, starts then shuts off
What is your question?
2007 Chevy Silverado Classic has an intermittent no start issue. The truck cranks, starts then shuts off. When this happens there are no gauge warning lights when the key is in the on position. Sometimes the truck will go for a week with no issues, then it decides to do this issue. Or I wait and keep trying to start the truck and the issue goes away. Other times, I let it sit for a day and the next day it starts and runs like there was never an issue. This has been goin on for eight months.
I have a YouTube clip on this issue. You can look up it up with title: Chevy Silverado 07 NO START....no gauge warning lights key in on position....need help
Parts I have changed:
ignition cylinder
ignition switch
BCM
PCM
checked all grounds for clean connections
ignition fuse
How long has your 2007 Chevrolet Silverado 1500 Classic had this problem?
RepairPal Certified shops can diagnose and repair your 2007 Chevrolet Silverado 1500 Classic. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
For all these parts, you had a GM diagnostic tool able to program components for proper use?
That's a lot of expensive parts guessing -- seeking hands on testing from a professional would have been less costly, and would have resolved the problem. That's still my best suggestion.

I sent out the PCM and BCM for programming. I talked to two mechanics and they said they need to see the problem. This is intermittent so when I took it in, the truck was behaving with no issues. I cannot reproduce this issue, the truck picks and chooses when it will have the issue.
The mechanic was able to get the truck started. He found that the fuse box was dirty and full of seeds, like the cover was left off for a long time. The cover has always been on since I've owned the vehicle. He cleaned it out and started checking the fuses/relays. He could not find any issues with them. In the process of pulling out and plugging back in some fuses, the dash gauge warning lights came on and the truck started. They monitored the truck for another four days, but could not reproduce the issue. This is an odd intermittent electrical issue that will probably happen again, but hopefully not.
