Porsche 996 cranks but will not start

[Paulnico]

Hi, I have a 2001 996 turbo tip. Yesterday I drove a short trip stopped unlocked my centre console glove box, relocked it then the car would not start. I've since had it checked out for fault codes only to fined 4 codes relating to the immobiliser.
P0015 no engine start possible. W lead (dme immobiliser) open circuit.
P0021 no communication with PST 2. This fault is stored if the k-lead is short to ground.
P0021 no passenger compartment monitoring. Interior monitoring sensor fault.
P0030 airbag signal acknowledged. This is triggered log.
None of the codes can be cleared and I don't know the next step.
Originally the car would crank over, fire then die.
Now it cranks over does not fire at all.
Any suggestions please.
Paul.

Yes I tried both keys and the same result.
Both keys will lock and unlock doors and activate the alarm.

I can't hear fuel pump whine, but after cranking for 20 secs it smells of petrol.
I had checked all fuses with multimeter none blown but some feel loose
Are there any relays I need to check, why is the the code reader stating an immobiliser issue?

Rev counter does flicker when cranking, volts drop down to 10v even with slave battery fitted.

Still need help if anyone has more suggestions please

Do I need to take it to main dealer? Any suggestion I'm in north east Middlesbrough area?

Just had time to check today, and no damp under the seats, I changed all fuses relating to alarm, I checked voltage and that seems ok 12.5v. When I turn the ignition on I can hear the pump spin up the stop, after a couple of long cranks on the starter I can smell fuel I'm the exhaust but no sign of life.
I've found a local independent but he wouldn't impart any information other than £70 to look at the car, even when I told him all the symptoms and the codes, he would not suggest what it could be or any costs ranges,

Good points, I tried them this morning, I removed the battery to clean water and stuff from the drain bungs, noticed the alarm unit had corrosion on all of the terminals, cleaned this with contact cleaner and fine sand paper, refitted batter, cranked engine for 10-15 seconds no fire, removed fuel pump relay crancked 2 x 10 seconds not a flicker.

But reading your other note regarding the shopping centre car park, when I stopped the car last, as stated I opened centre console, I then replaced the key and thought I would check the oil level, I was going through the process sitting on the level part of the drive out side of my house, "This is a shared drive entrance" my neighbour turned up so I opened the gates to my drive with a remote controller, went to start the car that's when it would not start, could my gate remote have effected the immobiliser?

Hi, thanks for your thoughts, all ignition lights come on, air bag light goes out after 3 secs engine turns over at good speed lights drop off while cranking, just will not fire, but I can smell fuel from the exhaust.
No light in glove box.

I decided to take it into a local specialist, and the diagnostic indicated that the fuel injection was inactive, after another 2 hours of testing, they called me up with quote to replace the fuel pump, I will report on the outcome in a day or 2. The quote including diagnostic, pump, labour, vat is £850 wich is a painful hit just before Christmas.
