I have a bunch of experience on the 911 end.
Picked up a S2 to have some fun with.
Had a friend look at the car in KC - checked out for the most part.
Had it delivered - guy started it right up - backed it off the transport - put it in the driveway.
We admired for a little bit - went to put in the garage - and it wouldn't start.
Cranked over - Tach not jumping -
no power to 86 on the DME Relay. tried a spare (luckily uses the same as the 964 engine in my 1974)
Under the dash - looks like a speaker for an aftermarket alarm?
Tried to by pass the alarm - and heated up some wires - poking around the fuse box and it looks like it has a few hacks to bypass maybe a brake light.
So what I've done -
- Charged the battery to 100%
- Changed out the DME Relay
- Tested to see if there was voltage at 86 with the key on at the dme relay (there was not)
- bypassed the factory alarm - lead 1 got hot
- removed distributer cap - checked and cleaned all contacts.
- removed coil and cleaned and checked all contacts
- tried installing the fuse at (12) for the factory alarm - alarm went off - even with key in the ignition.
Definitely seems like an immobilizer - some sort of block - car turns over - and again - it ran well when they backed it off the trailer - but now
where to go from here?
