987 wont start after pulling the security box under seat

[thstone]

I remove the immobilizer fairly often.

Sorry to say this again, but check that the connectors are firmly seated. If still no go, then pull off the connectors and look for bent pins.

The wire harness is fairly short and its easy to pull it out when re-installing everything. And yes, while it can only go in one way, I was able to bend a pin once and even though the connector was seated, the bent pin kept the car from starting.

You may want to pull the seat again to get it all working without having to work in the limited space under the seat.

I went nuts trying to find the cause for an engine that would start backfiring as soon as you touch the gas pedal and dying after installing the OEM throttle body.

The fault was a bent pin inside the connector, I was able to bend it back without breaking it (they seem kind of fragile), be gentle and proceed with care.

Good luck!
