Here is a video of my starting problem:
cold start video I'm guessing it's not getting fuel? Prior to this issue I would notice that when I would turn the ignition on (the notch prior to cranking the starter) when the oil and alternator lights would illuminate, something in the engine would turn on and I'd hear a hum. Now, it is completely silent. I relocated the fuel pump to the front a while ago. |

Blown fuse? Blown fuel pump? I had to replace my pump a few years ago.

Check the fuses on the relay board - drivers side of the engine compartment. There will be two "slots" - you're interested in the rear-most one - closest to the round relay. Also check "relay 3" by swapping with "relay 4" (assuming your heater fan works)
Edit: added diagram  |
