Today my 986 died on the Bay Bridge

I am no mechanic, but you have codes which are across both banks
possible causes:
a) bad MAF
b) problem with the timing chain ( read IMS)

Ok, I disco'd the MAF's plug, tried starting it, and failed. Replugged it in; failed. Am I misunderstanding the directions for testing your MAF to see if it's the missing link?

When trying to start it, it cranks, but no start. Keep the help coming...

When was the last time you changed out your spark plugs and coils? You should try unplugging the MAF and starting the car.

Tried; it cranked but wouldn't start. Spark plugs are 10k old, never changed the coils and have been driving it for about 25k miles. It has 92k on it now. Is it that time?

If you can tow it to Santa Clara, Marvin is the best!

I had over $3K done in work....would have cost me double that at the dealer and would have not learned a thing like I did with Marvin.

check the usual suspects...fuel /spark....with a scan tool look for crankshaft position sensor voltage /signal

Thanks for the referral; should I end up going that route, I'll consider sending the business his way. Does anyone think it's the coil packs? My buddy and I are leaning in that direction. In case the fuel sender was bad, we just added some more 91 octane.. it appears that fuel is being delivered.

Ugh.

First off, do you try pressing the gas pedal when you start the car?

If you have the time and want to save the money, I'd start off with all the common and easy stuff and try to build my way up from that. Then maybe take it to a mechanic.

Reset the car's computer by disconnecting the battery for a few minutes, then try starting it up again and see if it gives you the same codes
Check the oil, air filter, IACV, MAF, PCV, and spark plugs
Clean out the throttle body and carburetor, checking all the components around them in the process
Replace the coils, oxygen sensors, and maybe the MAF. They're designed to wear out anyway.

Ok.. tested the gas while starting: no difference. Air filter and oil are all good. I guess everything else begins mañana.
