I got the cranks no start after a head gasket replacement. I have not codes . I tried searching which is how I found this forum. We only have the one key. I really don,t know how I could have affected the immobilizer from a head gasket replacement, but I am open to suggestions. Thanks in advance.

Green key is flashing while cranking? Do you hear the fuel pump priming or running at all?

Yes, cranks while flashing and I do hear the fuel pump prime. Thanks for the reply.

If the green key is flashing while cranking the fuel pump won't run/prime.

While doing the head gasket replacement did you unplug the crankshaft position sensor?

It's literally two posts up...

Runs from the top of the thermostat housing to the radiator support.

Try the other micro-chipped key?

Did you replace the PCM? Did you have alternator problems?

"Large metal objects, key fobs, other immobilizer keys, and other transpondars can interfere with the immobilizer
signal. If an intermittent program is suspected, remove the ignition key from the key ring."

Check fuses #6 (15A) and #9 (10A) in the under-hood Fuse/Relay Box.

Any other things not working on the car presently?
