I ran into a problem where my ECU no longer comes on with key on. All fuses are good. There must be a signal wire that lets the ecu know when the key is in the on position. Is this wire in a "inline fuse"?

 

How did you determine this? Can you give a little more info? Thanks.

I determined this by checking the power connections on the computer. I have a felpro inline with the factory. I have a constant 12 volts going to both computers. However when I turn the ignition on the computer is not getting the 12 volt signal to prime the fuel pump etc.... If someone can check a terminal, black connector number 30, on there factory computer to see if they get 12 volts with key on that would be great.

Thanks
