Okay, I lucked upon this great 1991 Chevy K3500 4x4 on craigslist last November for only $1,000. My brother said he'd give me that for the 454 big block. Anyway, I let it sit at his house until last week. On Tuesday, I put in a new battery, then replaced the fuel filter, pump and sender. It started up immediately and I was in heaven. Took it for a short ride, and nerd that I am, I ran out of gas. Put more gas in, but it would not start up again. Had to have AAA tow me home. I've done a bit of research over the past day or so (that's how I found this site) so today, before taking the fuel pump back (while I can) I'll try to see if some of the frequent fuel issues are mine as well. I look forward to sharing my progress with this wonderful find.
