I havea '98 Silverado 2WD. I just bought it about a month ago and I'm having some problems with it. Somewhat randomly, it won't start up. When I turn the key it'll turn over and try to start, but it just won't fire up. The fuel pump is working, because I can hear it turn on. I just put new spark plugs in it and it gives a spark. The other day when I tried starting it, it did the same thing, it wouldn't start. I checked the spark plugs and they were soaked in gas. I dried them up, and still it wouldn't fire.
I decided to have it towed to a shop to have it checked out, and once it got there, it started right up, no problem. What could possibly be the problem? It seems like when I don't use it for a little while (1 or 2 days), the problem occurs.
Please help, because I have no idea what to do..[:@]

I have a '95 Chevy Silverado. I had the same problem. After about 6 months of 'process of elimination' I found that it was the 'Ignition Starter Switch' The dealer wanted $348.00 for the switch, and 3 hours labor @ $90.00 to replace it. Long story short..... go to '1AAuto.com' - I think I got the switch for $159.00 (Cheapest place for the exact part you need), and I was able to change it out my self. Very Easy to do. Took about an hour and a half. It fixed the problem, and the truck has been running strong since I did it. It was doing the same exact thing as you are describing on your '98. 100% - your 'Ignition Starter Switch'. The switch itself is attached to the right hand side of the steering wheel column, under the ignition cylinder where you put the key in. The part comes with the whole wiring harness already to go. Just unplug old 1, and pull the wiring from under your dash, and plug in the new 1. THAT EASY. - Jason
OK. I'll check that out as soon as I can and hopefully that's it. Do you know if there is any way to measure if the switch is working properly or not? I don't want to spend $150-200 and then have that not be the problem, you know what I mean? I appreciate it bud, I'll let you know if that was it!
Yeah.. I have good pressure. Also, my spark plugs were soaked in gas when it didn't start. After I dried them up and but it back in, it still wouldn't start. It's like it's flooding for some reason.. Either that or it's not getting a spark quick enough and then it floods. I have no idea.... Would the spark plugs be wet if there is no fuel pressure?
