Have you had the fault codes checked at all to see what codes are setting with this issue here?

no fault codes setting anywhere. no strange data except under immobilizer it says "ban". im using a modis. cant view any other immobilizer data with this scanner.

Are you seeing spark at all on any cylinders?

Customer: replied 1 year ago.

nope. no ign pulse, or fuel pulse at ecm. all data (ckp, cmp, tps, etc.) look good

Expert:  Pete replied 1 year ago.

Usually the immobilizer doesnt shut off spark.This may be a possible fault with the electronic ignition switch itself.I have seen the ignition switch fail in the past before and can cause issues like this here.If you have not had this switch tested at all this needs done to see if the switch needs replaced.

Let me know if you need anything else and feel free to rate my help here as this is how I receive credit for my time.

Thanks Pete

Thanks Pete

immobilizer does kill spark and fuel in these models. As suspected, immobilizer was bad. Ended up just trying a junkyard immob and green key light now comes on with key on. I knew that was a vital piece of information. Locksmith friend coming over later to program it to the vehicle

That is great to hear the fault has been located and resolved.If you need anything else let me know.

Thanks Pete
