I was on the trail today and the truck was running great... until I went to start it up after a break. It cranks, I have fuel pressure, I can hear the pump, but it doesn't fire. There is no fuel coming out of the injectors either. I also noticed that the SES light doesn't come on when turning the key like it used to.
My fuse panel is hard to read, so I checked every fuse. It turns out the 10 amp fuse in the middle near the bottom of the fuse box was bad. I replaced it and still nothing.
The truck is still on the trail, but due to the lack of diagnostics equipment, I had to leave it. I do have a theory though... I soldered the chip socket on the ECM myself a couple years back and it has worked great. I know I'm not the best with a soldering iron, so I'm going to grab a multimeter and check all those soldered connections.
What else can I check? I think I'll also hit the yard and try to find another 7747 ECM so I can plug it in. Also, if I have to do some soldering on the trail, what size of power inverter would be necessary to run a small soldering iron?
EDIT: I also replaced the TBI recently with a 46mm bore and 68lb/hr cop injectors.
