Check to make sure that the jump wire between the main relay and fuel pump relay is present. You should see a red wire running between the two relays. If its there, check to make sure both relays are working. If they are, I would suggest you try to find someone who will let you use they're ecu for testing to see if its the ecu. Just make sure everything is grounded properly or you'll burn it out. While I'm on the subject, are you sure everything is grounded well and that the battery is connected correctly? I know its a dumb question but I have to ask.

What engine is it?

My eta engine as a reference pin on the flywheel that is used to determine crank position and will not start unless the sensor is picking up that point.
