New update:
Had a guy say might be air in injection system, (after sitting for a few minutes, car will start but not stay running more than 2 to 3 seconds), so i opened pressure check port, ran fuel pump until steady flow. Checked fuel pressure, approx 40psi, getting spark, plugs get fouled with gas, sometimes get a backfire. No steady start though. Timing appears to be good. Could fouled MAF be a/the problem? I'm at wit's end. Trying to avoid towing to nearest Porsche repair shop, 2hours away.
