My new A4 won't start yet...Fuel related

[southcoasting]

So after a couple of days of doing a few things (flush, electric fuel pump conversion, new OPSS, cleaning carb, new fuel filter/separator unit, fuel hoses) to get it ready for first start in a few years, I am not getting fuel priming from the pump

Here's the story:

I had my old extra fuel pump from Destinada around so I went ahead and used it...But got no kind of priming/pumping...I did not get the usual ticking noise I get when I used to on Destinada telling me the pump is sending fuel...Tried bypassing the OPSS as well...Nothing

So I went and pulled the newer pump from Destinada to see if I just had a bad pump but also got nothing...

So I thought, that eliminates the fuel pump being bad...and started looking at the coil...I noticed this odd piece in the attached picture that I am not quite sure what it is...It is not on Destinada's A4 so contemplated yanking it...I touched the connections and they seem really flimsy on this contraption...

Any ideas what this is and how to yank it and retrofit the existing cables going to it?

Its a ballast resistor to reduce the power dissapated by the coil. It protects the coil from overheating and cooking itself. There are several extensive threads on the topic in this forum.

If it's faulty, it will keep the boat from starting. And if the fuel pump is (incorrectly) wired to the reduced voltage side of the resistor, it's failure will also stop the fuel pump from running.

For a very quick, short test, it should be fine to simply bypass the resistor, but you should strongly consider keeping it if you have electronic ignition.

Turn it over and see if you have spark; check plugs and see if they are wet with fuel. If problems noted correct, and if it still doesn't start do a compression test. Valves or stuck rings can be problematic as well on an engine that hasn't been run in a while.

Thanks guys...So after some troubleshooting, I bypassed the resistor and ordered a new one for now...

Still wasn't pumping fuel...

Until I realized that the Racor pumps need to be grounded! Jeez...Spent a ton a ton of time and this whole time I had not realized the Racor pumps needed to be installed with a grounding attached to it if installing it on a bulkhead like I am doing...So used to messing with it right on the block on my old A4

So after manually priming the pump because it would not pull gas on its own (using my old mechanical pump), I am now getting fuel to the carb...took a quick look at the incoming hose on the carb...

I did have to bypass the opss in order to have it prime...

So I am excited because I have eliminated the pump and coil from being an issue...Now it's down to my spark...I bought a cheapo Harbor Freight multimeter to test some things tomorrow...I did not end up changing the plugs yet which I usually do...A good idea to change those too while I'm at it anyways...

Little by little I will get this thing started!

I should have bought a compression gauge while at Harbor Freight to run compression tests with...

Great news is, I got her going today!

So the fuel related issue ended up being an ignition related issue after the fuel feed issue was fixed...

Replaced all ignition parts but I believe my issue was mainly revolved around the ignition wires where they were a mixed up...it was to go through this though because I got to learn a ton about ignition and now have extra parts in case something goes wrong...As Don says, 90% of ignition issues are primary ignition based

I took a video but don't have youtube but I have it up on my one drive
