Most heat sink isn't really fuel-rated. It could break down and clog your pump filter/sock. Definitely look up the product you used and see though.

As culberro said, the gray box is probably a filter capacitor for ignition noise. You can unplug it and see if you get rpm-varying audio noise on the radio (once running).
Are you using the original power stage / ignition module? It would have been in prime crunch territory and may be dead now.
If you want to test the EZ117K box by itself, connect ground to pin 20, +12V to pin 6, and measure pin 4 which is power to hall sensor. Pin 4 should be just slightly less than your +12V voltage (roughly a 0.6V diode drop lower).I cleaned it up and reflowed some ugly solder joints but the hall sensor still isn't getting any power.
