1993 240sx not starting

[accordblake]

First of i did search and found nothing close to my problem, so on that note here it is.

i picked up a mint shell, as in no harness or nuttin. I have a 93 ka that was runnin perfect just body was done. So i took everything out and swapped it over. I took the motor out in perfect running condition and put it in the shell. I took the whole body harness out and stuck it in the new shell. I took the whole under dash harness in stuck it in the new shell. I used all of the parts off my good running ka on the new shell is what i am saying. So now i go to start it and the damn thing only cranks and cranks and cranks.I check no spark, no fuel, no power to maf. So next step i look at ecu and turn car on and no light turns on. I change the ecu several times i have alot, and no power. There is power going to the blue plug that plugs into the ecu, and i opened one and check the pins and power there but no light is turning on, on the ecu. Does and one Have any advise for me please

Check all of your body grounds and fuses.

[accordblake]

check all and all good, any reason the light on the ecu would not turn on?

[JeromeS13]

If you're sure its getting power, then it almost has to be a bad ground or a bad ECU.

Next time, include a description of the problem and year and model of the car in the title.
