I am having a hard time with the wiring in my 240. It was done by someone who had no clue what they were doing and so its extremely shotty. I may be sending the harness out to get it redone but before I do I was wondering if somone could take a picture of where the fuel pump connectors plug into in the engine bay? I cannot get the pump to turn on when I turn on the ignition and I am getting no fuel pressure but when I wire a 12V source straight to the pump it runs fine. I am running a 255 and my only guess is that I am missing where it plugs into in the engine bay. Any help would be greatly appreciated, you can send the pics to [email protected] or just post them here either way. Thanks again for the help, and I searched but could find no help about the pump connectors so sorry if this is just a waste of everyones time.

There is a lone relay for the fuel pump. Depending on the engine wiring harness, it should be right next to the ignition relay next to the ECU. Check to see if it's working. And, Or try to send power to the fuel pump from the relay plug. That would be a good start.
