Default 00 looses spark after cranking

My 00 Bonnie decided to die while at the mechanical shop. Replaced crank sensor and obvious electrical stuff, when cranking the key I get plenty of spark, after that, no more spark. Looked at everything and anything under the sun and stumped. Anyone have any ideas, also saw a possible pass key issue where the computer rejects the key. Thanks for the helpdh2

Please put your trim in your signature please. This helps us knowing what kind of car you have.

Also, could you please list the other "electrical stuff" that you replaced?

Sorry, 2000 SE non supercharged. I have replaced plugs, wires, crank sensor. Plenty of fuel pressure, spark when cranking but when it seems to want to "catch" I loose the spark.

I would check the connector at the ICM to ensure it'* not loose. Check connections at the PCM.

The way the passkey system works in your year is to disable the starter. Therefore the spark issue shouldn't be related.

Having swapped the crank sensor, I'd look over the belt routing, wiring and if that passes, consider the ICM and pcm as they ICM hands off spark timing to the pcm after 10 seconds of running. Kinda sounds like the handoff is getting fumbled.

IS there a way to check the passkey system?

You've checked it and the starter rolled over, so its good. When you had the CPS replaced, did the shop do a case learn?

The case learn, I am not sure. Could you describe further what it is?

Let'* see if I type faster than Kevin....lol

Case learn optimizes the pcm'* knowledge of the exact crank position to TDC on the cylinders. Most of the time a learn is not needed for a car to start. In the case of yours...I'd say it died before...therefore it "shouldn't" be needed. However you can't ever really tell w/o doing it.
