Go a 2000 impala and have a problem,
The under the hood lower fuse panel I have no power to all mini fuses but the 25 amp fuses for the fans.
All the 60 amp and relays work in the panel and all the relays and fuses in the upper panel work but found the drivers side PCM crank fuse has no power either.
Try them with the ignition both on and off but nothing?
Underhood Fuse #2 (60 Amp) in the bottom outside fuse box is directly connected to the battery, and feeds the Ign Relay (in the bottom outside fuse box) which feeds most of the mini fuses in the bottom outside fuse box
Double check that both sides of the Uhood #s 60A fuse have power (and are making good contact with the contacts in the fuse box) and make sure the Ign Relay is working and actually passing current across it's contacts...
You won't have power to the crank fuse if none of the other fuses have power...
If you only have power on one terminal of the IGN Relay with the ignition on, then you either have a bad Underhood #2 60A Maxi Fuse or a bad 10A ABS/PCM fuse (even though they show good) or a wiring problem between those fuses and the relay
You said only one of the IGN Relay terminals has power, what color is the wire going to that terminal?
EDIT: Do you have power to any of the terminals on the crank relay? If so, what is the color of wire going to that terminal?
