Won’t start

[rdrustdmd]

1987 930 having starting issues. Engine has been rebuilt and was running fine. This summer I had problems with starting when it got hot outside and car sat in heat. When cool, engine would start. This did this several times and now won’t start at all. Do not hear the fuel pump come on. Checked fuse for fuel pump and is ok? Could this be fuel lock, bad fuel pump or some other fuse I do not know about? Any suggestions would be most appreciated.
