Tried a few times to start the 04 Silverado 1500 today and got nothing at all, then a few minutes later it started perfectly, and has been fine since. I had a similar problem with my car which turned out to be a bad starter relay. Random non-starts until it completely failed. I'd like to go ahead and replace the starter relay and whatever else could be causing the problem. I'm looking at this part on RockAuto - Link. At $6.92, I'm thinking this is a general relay and not the starter relay. The one for my car was around $50. What part do I need, and where can I get it?

If there's another source for my problem, I'm all ears.

Locate the starter relay in your electrical center using the legend inside the lid, or if missing, in your manual. The relay is very likely the same as several others in there. It isn't literally the relay for all the current to the starter; that's the starter solenoid's job. Anyway you can swap another relay in place before spending money on a new one and waiting for it to arrive. My suspicion is that the relay is probably fine, but you could rule it out that way. Most likely suspects are the starter going bad or ignition switch, but those are obviously more expensive and more labor.

Check your ground wire from the battery. We had a Tahoe at the shop that did something similar and it was corrosion under the ground cable that went to the block. It started fine and then it didn’t even crank. I don’t know if it was intermittent because I looked for a problem right away. One clue I got was when we hot shot it because my original thought was it was a low battery. It started fine with a hot shot, but only when the ground from the jump box was hooked to the aluminum bracket on the engine. It acted the same with the ground on the battery. You could have just enough corrosion to be causing an intermittent problem, or maybe condensation making you lose ground and later it dries up and you get better contact.

The parking lamp relay looks like it is the same thing, I'll swap that.

I can see it being the ignition switch and have been planning to replace that for a while.

The block? I've tried tracing the ground back and I lost it at the rear of the oil pan, passenger side. Or I'm looking at something else. I've got the "this can't be right" feeling, so I came in to check.

Sounds like you are looking for G102 and the attach point for the negative battery cable. Two locations. If it is a V8, then look for the ground wire attached to the left side of the block, below #6 spark plug. If it is a 4.3L then it is located on the front right side of the block near the lower portion of the head/block area.

It's the 4.8.

I'm looking at a firing order diagram here, just to be sure I have the right "left-"

Link

So the negative cable crosses under the engine and attaches to the opposite side of the block?

My relays are glued in good, probably with mouse urine. Not sure how I'm going to get them out without breaking them.

Sorry, I got it backwards. The ground is on the drivers side ( left side) under the #5 plug. It is down near where the pan/block meet. Also check the grounds at the back of the heads. Damn old age creeping in!

No problem, I can honestly say I'm getting older too. I did spend some time looking for the ground on the passenger side though - I suppose that is the starter motor I was looking at? I was questioning the sanity of the GM engineer who put the ground above the starter motor. After pulling the HVAC door actuators, I'll believe GM would put anything anywhere, as long as it was hard to get at.

Found the ground. Is there a better way to get at it than feeling around from the top? I don't see one.

I would try loosening the plastic wheel well shield, to gain some clearance. Definitely in a fun spot.
