Starting issue. Cranks-no start

[tradergarry]

Hi, I could use some help. My Boxster left me stranded at a light. Would crank but not start. After checking fuel pump fuse was ok I had it towed home. I jumpered pins 30 and 87 on fuel pump relay and it started. Ordered relay from Pelican. Installed, it started, drove 5 miles to an appointment, then would not restart. Towed home. Before I hooked up Durametric I tried ignition and it started. Durametric revealed 6 codes. The first one has been ongoing. The last 5 are new.

P0455:
Porsche fault code 94 - Tank vent system (major leak)


P1130:
Porsche fault code 361 - Oxygen sensing adaptation idle range bank 2


P1341:
Porsche fault code 174 - Camshaft adjustment bank 1 below limit value


P1579:
Porsche fault code 111 - Crankshaft sensor


P0336:
Porsche fault code 110 - Engine speed sensor Open circuit


P1124:
Porsche fault code 167 - Fuel pump relay below limit value

Regarding the first ongoing code, I've replaced the gas cap, carbon canister, vacuum canister, secondary air vac valve, 2 check valves. Still got that code but was running fine so I ignored it awaiting more insight.

I did not think to unhook maf during start failure. I did replace it within 10,000 miles though. It was running normal prior to problem. I did detect a very slight miss at idle similar to when I had a hairline crack in a coil pack.

Any help would be greatly appreciated.

Thanks,
Garry
