Check for 12v at the injectors with the key on. You should be able to hear the fuel pump kick on for a few seconds when you turn the key to on. Also a lot of people tend to mix up the fuel lines onto the fuel rail.

the ignitor is on near the fuel filter and it looks Kinda dimond shape. and it has a 5 or 6 wire plug.

tdc is related to Timming and it means Top Dead Center. this happens when it #1 piston is at the top. check to see if the Dampener is on 0 degrees and #1 piston is at the top.
