Message	Ok I put a new motor in a 90 NA. According to previous owner the injectors are brand new. I dropped the new motor in and crank but no start. I was looking over everything and my kid brother says should that be smoking, pointed to the ptu. I quickly unpluged the battery. I have stripped back the crappy nissan ptu fix all the way back to the crank sensor with out finding any problems. I then unplugged the ptu and put the battery back on, wiring my amp meter in series with the positive side I got an amp draw of 4.44 . I then unplugged everything in the efi harness one at a time ( to verify the individual components.) all the way back to the ecu with no change. Then plugged them all back in one at a time. No change. I started pulling fuses (the key being on this whole time.) when I got to the one labeled LTG (passengers side next to battery.) and pulled it the amp draw went to zero. So what is the ltg fuse and what does it control? What suggestions for ptu problem. Thanks Scott
