Chevrolet Silverado 1500 Intermittant Failure to Start
Chevrolet Silverado 1500 Problem
Average Mileage: 84,250 mi (2,000 mi - 170,000 mi)
Exactly same problem as described by Schmackster1952. Problem is totally intermittent, but frequency of occurrence seems to be getting higher. Battery, charging, and all other electrical system components seem OK. I have tried moving shift from park to neutral; took key in and out of switch; nothing seems to be related. Is there any switch, relay or sensor that could cause the truck to "think" it is not in park, or the engine is already running, or whatever else might keep it from engaging the starter motor. When it decides to act right, all is will. Anyone else found a solution?
Will turn key and it is like no power from battery to starter, but have lights, radio, etc. Turn key again or sometimes multiple times, to no avail. Then, turn it one more time and it starts. Then the next 15 starts, no problem. Sometimes hot engine, sometimes cold.

Chevy silverado 1500 2004. The same problem, random intermittent starting. I had had this problem before about 5 times and each time I disconnected and reconnected the negative battery cable it started fine. This time that didn't work. So I swapped the starter relay in the fusebox under the hood with the other identical relay, no luck. I crawled underneath the truck and tapped the starter with a hammer, no luck. I jumped the truck, no luck. I did hear the solenoid clicking. The door was open and the dome light was on. When I turned the key to start the dome light did not flicker or dim in any way.
Also, when the key was on, the battery voltage read about 12. When I turned the key to start, the gauge dropped down to 0 and stayed there until I released the key back to ON. Also, I keep the headlights on automatic with the selector switch. They stayed on while the key was in the on position with the truck in park, and died when I turned the key to start. The check engine light was on when the key was On and I think stayed on when I turned the key to start.
That was yesterday. Today was totally the opposite. I flicked the key to start this morning and heard it try to start. I flicked it again and it started. I did not jump or charge it. I drove it for about 15 minutes. The battery gauge showed 14 volts while driving, so the alternator was good. The headlights went off when I turned the key to the on position with the truck in park. Yesterday they had stayed on. The dome light did NOT come on when the door was open. I turned it on with the switch. The check engine light went off immediately after I turned the key to start. Yesterday it stayed on. When starting, the dome light flickered (I had turned it on manually today) , as it should. Yesterday it had not flickered at all when turning the key to start. But, yesterday the battery gauge went to 0 when trying to start. Today it went down just a bit while cranking, went to 0 for a half second, and jumped back up to 14 when it started.
Same problem reported by others. I especially agree with comments by 'visitor' who described the situation in great/accurate detail. I believe it is related to 'anti-theft' or 'alarm-set' circuitry. If I repeatedly lock and unlock the doors, either at the door controls or with the remote, it will start after some manipulation. I find it hard to believe that GM has not found the source of the problem and the fix....since many owners are reporting the same issue.

One more thing about my 2004 silverado. I already wrote a book, but forgot to mention that the antitheft icon would stay on yesterday when the key was on and it wouldn't crank at all. However, today, when the truck will crank and start, the antitheft icon goes off after a few seconds with the key on and stays off while the truck is running. It never flashed either today or yesterday though. And I don't know if the antitheft system disables cranking or starting or both.

just randomly wont start for the first time in the morning.....just walk away for part of the day or next day, and it starts. Different components are powered up each time....sometimes lights work great and horn but the next time something else works or doesn't work. It does seem to happen about once a month. Someone told me it could be on-star related. Any other ideas?....sad for a new car. Back to Ford I go
