1988 isuzu trooper won't start

[dennism0550]

my 1988 isuzu trooper sat idle for a couple of weeks. started right up to go to work but after work wouldn't start. Have a spare with bad motor so have exchanged relay sensor, ecm, ignition switch, tested fuel pump, exchanged 1 fuel relay in box but can't find the other one. I am not sure what my next move should be. Also if anyone has a good wiring diagram I would like to have a good one.
