I have no spark or injectors firing. Had ignition module checked. It's fine. Just spent 6 hours changing the crank sensor as it broke off. Also was fine. Fuel pump sends fuel at the filter. Simply won't fire. No code either. Any ideas? Typical worked great then dead.

Do you have 3 separate coils mounted next to each other? If so, they are mounted on what is called a DIC, Digital Ignition Control unit. Remove it and have it checked. If it is bad, you won't get spark.

This car has two smaller coils under the cover that plug into the ignition module. Would that cause the injectors I not fire as well? Thank you for the reply!

Sorry, I was thinking it was a V6. If it is the same set up, and I think it is, yes.

The plot thickens! Starting to test the icm. Power is there. Ground is there however no volts from the crank sensor! I just changed it! Ohms are 650 or so! The wires. Yellow and purple checked for continuity. Perhaps autozone gave me wrong sensor?
