Ran fine when parked. Next day crank with no spark. Scanned P0600. Replaced ECU with a new and programmed to the vehicle ECU. No spark but P0600 DTC is gone. Replaced crank sensor and can sensor with new parts. No spark. Tested ICM on two different units. Both test good. No spark. Coils all read 5.5-5.9 ohms. Battery over 12V. Ignition switch tested good in all positions. Engine grounds all cleaned and reapplied. I'm at the end of my abilities. Please help! -

Hi, replace original ecm ,check the connector for corrosion ,check wiring ,reset ,check
and erase codes, check for voltage on coils and injectors if equipped,and try the spare
key if you have one. -

Thanks for the reply. I've done all of what you mentioned except the key. I only have
one key and it is a plain key with no chip. -

Hi, if you are sure that this car has a no chip key,than the key is ruled out, than only
change the ignition module mounted under the ignition coils.
