    Just wanted to update everyone. I believe it was the distributor cap and moisture. Seems like it wouldn't start only after it rained and only would start after a week or more to dry out. I finally pulled the cap and rotor and they were very corroded. Replaced and it seems to be running great...

    I've read a ton of crank no start posts and none are like mine. I have a 98 Tahoe with the 5.7. I drove it for about a year before out of nowhere it decided to not start. I did some research and checked the IDM, coil, fuel pressure, etc. it had spark and even if I put starter fluid down it's yap...
