Ran When Parked - Sudden issue starting

[vkmotorsports]

Hi
I have a 2001 Boxster S, that I have driven nearly 2500 miles this year since May. I parked it in my garage in November first week, and it is mid-December now.

It did not start after that. At first I thought it was the battery, so I put it on a tender, fully charged the existing battery and tried again. No start, it cranks enough but does not start. All dash lights seem to work fine, and I am able to fold the convertible top back and forth.

Today I decided to give in and replaced the battery with a new one. Same problem, no start only cranks.

There are three issues I have now:
1) Car cranks and can keep cranking but does not start. Maybe it is the starter ? or the fuel pump ? or what else can it be ?
2) I checked the codes and I get a P0740. Is it the transmission torque converter that's preventing the restart ? What should I do ?
3) I try locking the car with the key remote and it tries it, then beeps twice and does not lock it. This is new behavior, since November, so I thought may have been the battery. But now even with a new battery, this happens. So I am confused as to what is causing this.

Please advise.

Thanks in Advance.

The double beep when locking indicates a problem with the security system. Whether or not the immobilizer is preventing the car from starting, I can’t say. I’m not familiar enough with it to know if it blocks cranking or if it blocks fuel/ignition.

So that may be a path worth going down.

I followed the advice on reset ignition thing from here

I closed the top and the windows closed up on their own.

After a lot of cranking the car started up. I drove it 10 miles. I tested the AC/Heat and Radio works.

However, I still see the following problems:

1) Window buttons do not function anymore.
2) Alarm system still does not function and beeps twice.

What else can I try ?

I figured it out. It was the 15 A fuse number C3 that was blown and needed replacing.
