P1571 Immobilizer - Open Circuit / No Signal

1. Try your spare key. If it works reliably, then its your key.
2. Check under your drivers seat. Is it wet? Did you ever get water in the car? The immobilizer box is under the drivers seat and if it gets wet you can have problems.
3. Check wiring harness to/from the immobilizer visually for problems. Make sure the connectors are fully seated. Sometimes something can get jammed under the seat and damage the wiring.

Does the immobilizer shut down spark or the fuel pump?

I recently had an issue where the motor would crank freely but would not start. I was away from home and didn't have a meter or any other tools, but I a passer by had a can of starting fluid. The motor coughed and sputtered on ether, but again, would not run.

An hour later it started up and has run fine since.

It never lit the CEL, but I hooked the car up to my generic OBD scanner and it found a stored code of 1530 which it identified as Camshaft Adjustment - Bank 1. That doesn't seem to be related.

I ordered a new relay, and I'm about to order a new fuel pump - unless someone has thoughts that it might be something else?

Ok so took the seats out. No loose wires checked and rechecked wire connections. Nothing wet under the seats. Do not have an extra key so cannot try that option.

Replaced the gas cap. Engine cover is off, I can smell gasoline when I try and start the car.

Idea's???
