Need some help diagnosing my 97 993. Here is what I can tell you:

Pulled the car out of the garage last week. Had the boot/doors open for a bit, nothing crazy long. Went to start it to take it out for the night and nothing. Lights come on, radio comes on, alarm arms/disarms but it doesn't crank, nada. We pushed it back in the garage and I did the following:

-Tried the other set of keys/fob. nope.
-replaced the DME relay. nope.
-pulled the battery and put it on the tender for a couple days. nope.

The only thing I can think of, based on some texting with the previous owner and my local guru, is that the ECU/M is not reading the immobilizer correctly and it's keeping the car "locked down". Can anyone help shed some light on what might be going on? I really REALLY don't want to spend north of $500 having the box flashed if I don't have to.

Thanks,
Joe

Try a known good battery or jump starter attached to your battery. Make sure the alarm is disarmed. The DME relay controls the fuel pump; so if the starter isn't cranking, that's not an issue.

That immobilizing system is very sensitive to a low battery situation. Like Jack suggests, top your battery up with juice, lock the car, unlock the car and attempt to start immediately. Cheers
