S-10 Sometimes Starts, Mechanic Can't Find Problem

Having a weird problem with our 2002 Chevy s-10. Here are the facts thus far....starts sometimes (if it starts there are no problems and no weird noises or electrical issues). When it doesn't start, all the electrical works without a problem, but the ignition is completely dead, no attempted turn over, no sound whatsoever. However, I did notice a buzzing sound coming from under the chaise on the driver side when I was trying to start it. The buzz lasted about 3 seconds and then turned off. Truck still didn't start though. The problem is, that the problem is intermittent, so every time we've taken it to the mechanic (even had it towed once), it started up just fine for them. Any ideas?

    Bummer...didn't work. I went ahead and took every fuse out and reinserted it just in case it was a different one causing the problem. No dice. The truck still won't start even those all the electrics are functioning correctly.

Yep, heres one. Start with pulling the crank fuse. The fuse is probably good, but you have a corrosion/contact issue. Putting it back will solve this issue. I would do all of them, as one will do it, more are sure to follow. Also do they relays. Next would be checking wires. Most times wires will loose connection at the plug, sometimes they will break right at the plug.

    Thank you for the suggestion and I'll give it a try this afternoon when it's not 105! Yuck. I know where the fuses are and it's funny you mentioned it because I just replaced one about a month ago. I didn't think to start there. Where do I find the relays?

SOURCE: 2001 s-10 wont start sometimes

first thing i would do is this take a test light put it on the small wire on starter and have someone turn the key to start, it should light up bright, (do this when it does not want to start like you discribed) if it does i would say its starter selanoid, if its a weak light, than your problem is in that wire between starter switch and selanoid. also chk.that small wire and see if it has a fuseable link. also chk. the main post on starter, they been known to come loose and it will do what you discribed. it will be the inside nut on main post behind positive cable the one that tightens up to selanoid.if its loose thats your problem, be carefull it tightens to plastic on selanoid.

SOURCE: intermittently all power lost after attempting to start

sounds like you need to clean the terminals on the battery and/or need to replace the battery cables, check both ends of where the cables attatch to the battery clamps, if they look discolored, melted or corroded in any way , replace them.

SOURCE: Car would not start. Mech stated had a fuel pump

sound as a grounded B+ wire (voltage supply), sorry but need a good honest electrician, he might need to tear down electrical harness to trace, find and repair if possible grounded wires, hope is not too much damaged

Have you replaced the ignition switch? Passkey wire broken can cause no start problem.

You need to find out what the error code is - Service engine soon means an error code was generated.

With the problem you discribed, it sounds like a coil problem. If a crack has developed in the casing, the crack size changes with temperature changes. Also make sure that the wires are in good shape.
