I bought the o-rings as well. Will I need heat transfer paste just replacing the pump?

Yeh, a former member that was a decent tech was adamant about using it. Ss a plug for what kind, Arctic silver is great stuff. I used it all the time on gm ignition modules.

Where are those radio shacks that used to be down the street when you need them ? Lol.

I have replaced the fuel pump and that did not make any difference. I am waiting on the fuel pressure regulator to arrive then I will try swapping that. Should be arriving next week.

TikTok guy knows what wrong - there ain’t no gas in it. 😂.

btw not related at this point but I finally broke down and bought a battery load tester from Napa a few years ago. So damm handy. With some aftermarket ignitions I found that even if the engine would crank over fine the battery wasn’t up enough to trigger spark. Again not really related but….

I wanted to give everyone an update.

I finally got to work on it some more this weekend. I replaced the fuel pressure regulator and that seems to have solved the fuel issue. The fuel pressure looks perfect now. Of course the starter went out so I cant actually confirm it will start. Im betting it will once I get the new starter in.

Thanks for updating us. Have fun with the starter, hope that goes smoothly.
