Help me track down my no spark issue

If you haven't checked already try ccci fuse under dash?

Anybody got a schematic of where this is located ?

Not to sound like a dick but its the fuse with ccci above it. Drivers side in front just above your left foot.

Didn't know he meant the fuse in the fuse box, thought maybe he meant something else when he said under the dash.

How far down the diagnostic trees did you end up?

Got voltage on B-5 while cranking but it's steady voltage not varying, took coil off module to check and found a broken tab on coil side replaced coil with new one from auto parts store and still no spark. Crank sensor and cam sensor are both new. Looking for a way to actually test ignition module before I spend 200 on a new one.

Don't worry about the cam sensor it controls injector timing not spark . I would check you ECM power and your crank sensor.

Um, no, this is not correct. The CAM sensor initiates both spark and fuel, so without the signal, you'll never see the first spark. Once you get the cam sync, then the crank sensor takes over and sequences the spark.

The ECM is responsible for firing the injectors, but it needs the "handshake" signal from the crank sensor to start the sequential fuel injector firing.

Learned that the hard way.

Guess I'll try and reset the cam and crank sensors next
