996 starting problems! Help!!

Is the throttle working? The butterfly will open when you press the throttle with the ignition switched on. Take off the inlet hose where it attaches to the throttle body, and you will see the butterfly.

Drop me an email and I'll attach the diagnostic sheets to a reply. (In the morning).
 
Sorry to hear about this Liam. I am by no means no expert and Richard will probably tell you i am wrong but could it be anything to do with the variocam solenoid.
ie Starting rough and then dying straight away.
I had to replace this on my car as it turned over but wouldnt start.
This is a real shot in the dark. Had to get an indie to do it though as it was a pig.
 
The item common to almost all of those fault codes is the throttle position sensor on the pedal. Liam mailed me to say that the throttle isn't responding, but the AA man got it running temporarily by actuating the throttle by hand.
 
Richard, where would i find the switch, and is it something i could replace myself or have to take to garage?

I sent you an email at 10 o'clock this morning with a diagram of the location of the throttle pedal potentiometer, and all the diagnostic sheets. Follow the cable from the top of the pedal, and you'll find it at the end, above the pedal box. As I said in my email, check the plug/socket connection first, as the potentiometers are mighty expensive (£450+VAT).
 
Being picked up on a flatbed 2moro [:(],(always looks so wrong seeng such a beautful car on one of those!) then off to an Indy, will let you know the outcome. Thanks for all your help.
 
Hey Liam,

Just read the full post.

Good luck with everything. Let us know how you get on!!!!
 
It's at the indy and they don't know what's wrong! Either Throttle switch £60 or Sensor £450+ starting with the cheapest and working way through! I had to order the part mind you, thought the point of a garage was that they do the work to get the vehicle sorted then give me the bill, obviously not, i could have changed the throttle switch at home myself! This is crazy, how is it never simple!!
 
Sorry haven't read the full post as I am on my way out, but could be either fuel pressure, injectors not pulsing, incorrect timing / ignition relay, fuel relay / pump or TPS. The key is process of elimination - rule out fueling, rule out ignition you are left with electrics and visa versa.

It will run and start with a faulty MAF, lambdas, crankshaft sensor, coil packs broken down (as not all will break down at the same time, will just run lumpy and fire on a few but still run), if your speed sensor is way out it won't fire up correcly. TPS won't pick up the throttle is open at all but should throw a fault, injectors probably won't throw a fault - I think the duty is measured through the ECU sending the signal not what they are actually doing.

Anyway hope that helps......
 
What diagnostic equipment does this indy have? They should be able to read the throttle position sensor on the pedal. If it doesn't respond to pedal movement, it would indicate that the sensor isn't working, or there is a bad connection.
 
Still without the car!!! Now been told it COULD be the throttle body! But they are not sure, only way to find out is to replace it, seems like another week without it min and still may not solve the problem. Wish i had gone to Porsche directly now, going nuts here. Not a happy bunny at all. [:mad:] Going round in @@@@@@@ circles.

 
Honestly i really don't care how much it costs now, (£360.00 for throttle body apparently, and this may not solve the problem) just want it fixed and back on the road!!
