So the injectors have 12VDC (or thereabouts - but battery voltage), as does terminal 86 on the DME Relay. I just pulled the ply-wood cover for the DME/KLR and am about to dig up some schematics to figgure out which are pins 18/35 so I can check for voltage there.

Guys, all these checks are comming back good? WTF! After all the cranking I've done, the battery is weak - but it Sounded like it wanted to start just now. To bad it's getting ready to rain, and the car is now sitting outside/unprotected (no room to work on it where it would be protected from the rain - and Much to steep of a hill to get it back up there).

Ugh... some 'welcome to Porsche ownership' - at least I got my Rennlist sticker to put on the car - maybe it'll behave better once that's applied.

 

ARGH!!! It just ran for like 5 seconds and died - won't restart. I just pulled the Dist. cap and reinstalled (wanted to make sure everything was good in that region) - so if that's the case, I'd have to assume that the DME (and everything else) is functioning properly - I think that battery charge has a lot to do with the issue no. And me with no charger/spare car to jump from. Argh... now I have to wait for the GF to come home before I can even try again.

At least this is the best news I've had to this point.

Damn, there needs to be a no-start FAQ...

 

As a new 951 owner, this sounds like my worst nightmare. I can't offer advice from experience, however...

If you have a high-speed internet connection, you can go to <a href="http://www.ninefiveone.com/" target="_blank">here</a> and download the Factory Service Manual(s). Volume 6 - Turbo (186 mb) contains a table with a 16 step procedure for diagnosing problems (Section 28, Ignition System, page 28-16.) This table gives 13 possible reasons for a no-start problem, starting with the basics (grounding, connections, power to DME/KLR/fuel pump) and ending with the less common (ignition signal.) It provides diagnostic steps/measurements for each condition. It also provides pictures, etc. for connectors, grounding locations, ....

If you don't have high-speed connection, I know that the manuals are available on (probably illegal) CD on Ebay or from fellow Rennlisters or legal hardcopy from most suppliers (Paragon Parts, etc.)

Hope this helps. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />

 

Ok, after running all the checks, pulling and inspecting a half-dozen other things myself and waiting 4 days - I finally got it running today. I guess stuff finally just dried out enough to allow a running condition as it ran VERY poorly at first and even now (after 100 miles) still doesn't run well when on boost, I think things are getting better. I guess that 5 gallons of contaminated gas added to a tank to top it off could introduce enough water to screw with things like this - so I'm just going to add some alcohol and run it for awhile.

Damn, I need to sit down and do a basic FAQ of no-starts while this is fresh in my head....

Thanks again to the few who helped.. <img src="graemlins/beerchug.gif" border="0" alt="[cheers]" />
