Made an edit and added one. Not sure what the grey one is with two wires. If you can post what the wire colors I might be able to help you.

Anything that is on the engine should have a home. Look for what they could plug into. If you have not plugged in the ignitor the car will not get spark. It looks like you have a few items in there from the L that are no longer needed and need to come out of the engine compartment.

Does the CEL light up when you turn the key to acc.?

Sounds like you may be missing the diode.

CEL= Check Engine Light

If the cel is not turning on, then your ecu/fuel pump won't turn on.

Sorry, i worded that poorly. If your CEL is not turning on then the ecu is not turning on.

azn0boi04 Are you positive the diode was wired in?
