hey guys I could really use some help. I’ve always been a ford person so I for the most part know my way around those trucks. But I’m in no way shape or form a mechanic, I just know a thing or two and like to figure things out. I’m working on a 1990 Chevy 3500 dump truck at the place I work cause we are hurting on trucks so I was tasked with getting it running. It ran two years ago when parked. First thing I did was replace the battery, so I cranked it and it wouldn’t start, then I realized I should drain the gas since it’s been in there for two years or so. Did that (now the sending unit won’t read so I probably messed that up but that’s the least of my problems) hooked all the lines back up put abt 3 1/2 gallons or so in it and cranked it and got nothing. I can hear the fuel pump running but fuel isn’t getting to the engine. It will fire off gas or ether put down the intake. So I guess what I’m asking is what should I check for before trying to tear off fuel lines cause that sounds like a major pita. Thanks I’ll try and post somepictures if I can figure out how to do that oh and it’s a small block 350. Also I noticed two fuses were missing in the box labeledpower I’ll take a picture of that and put it up too. Thanks for the help I’ll take any ideasor suggestions, I just really could use the advice
