1jz No Start!

Well the car will not start. it will crank over but nothing, i know the fuel pump is not turning on. and my wideband and safc will not turn on either they are wired into the wires going into the ecu.
My first thoughts were either my ecu went bad or my main fuse went. ive opened up my ecu and dont see anything burned or any traces or anything but i dont know how to test my main fuse. i took some pics dont know if you can tell from the outside of it i wouldnt think so though.

well it wasnt the main fuse. any ideas?

Check for blown fuses and codes.

If your fuel pump isn't coming on, did you check the EFI fuse?

Check for blown fuses and codes.

I dont have a dash or gauge cluster to check codes with.

I did its good to.
i replaced the main fuse and nothing changed, iam starting to think it has something to do with all the various wires spliced into my ecu wires gonna check it out more tonite.

try running power directly to the pump from the batt.. see if its good or not

Well i kinda figured it out. iam not getting power to my ecu. dont know were iam loosing the connection. but ive ran a wire strait from the battery to the ecu with a fuse inline. and it works just fine for now.
