Oh I figured out what's causing my hot start issue. When I have the car on I get a good 55psi fuel pressure but as soon as I shut it off, the pressure bleeds off immediately instead of staying pumped up. So the ecu is expecting a primed up shot of juice and says “no baby you're already worked up enough as it is” but the problem is that she's on antidepressants and can only build the pressure up, not hold it anymore basically the cylinders aren't getting any fuel for those first few cranks.

Replacing a fuel pump isn't too tricky as the cars usually have some access ports built into the sheet metal to pop out. Well, like the 996, this uses a saddle tank and a two-part master and slave Venturi system to equally suck from both basins within the tank. The problem is this chassis was never designed for such a tank to share room with Rwd components and what I'm saying is there aren't any access holes. You have to either drop the whole rear subframe and driveshaft, or you can lift up the carpet and cut your own access holes very carefully.

There arent any clear photos of exactly what to cut and where either. And the factory pump is no longer available and all you can do is rebuild the existing pump with a new motor and regulator. What brand is good depends on who you ask and everyone's got an opinion.

I think I'm gonna go for the cut method. I'm not going to start in on it until the Porsche is running though.

Just waiting on a few more o-rings and a hose before I can put it back in - but in the meantime I decided to do another leakdown test on that bad cylinder.

It was down around 12% and I was certain it was a stuck ring or something with the cylinder itself.

Spraying some oil in it before hand allowed me to trace it to an exhaust valve.

So as long as I'm not getting any misfires from it I'm going to just let it go for now and see if it gets worse and try to diagnose what exactly is causing it. This is all good news though. Being able to stay out of going inside the block avoids an $8-15k job.

I can't believe Maddox got a job with Harbor Freight.
