2000 Bonneville SE.

Cranks, doesn't start. Fuel is at the rail, but there is no spark. I pulled a plug, no gas on them.

Injectors all ohmed between 12.6-12.8 ohms.
Swapped ICM to known good ICM.
Swapped coils with known good coils.
Replaced crank position sensor.
Replaced cam position sensor.
Checked all fuses. Swapped relays with known good and working relays.
Good fuel pressure at the fuel rail. FPR is good too.

So yeah, I'm lost.

Thanks,

Chris

I've also hooked it up to a scanner, no codes, and no pending codes.

I should also add:

Replaced faulty ground under the ICM. It is the single wire ground that it attached to one of the ICM mounting bracket bolts.

It is not a Security/VATS/Pass Key issue.

I've looked over all of the wire looms, nothing looks cut/worn/frayed. Have not done any continuity tests, as I do not have the pinouts for the Cam sensor, crank sensor, or ICM.

I do not have a noid light to check for the injectors to pulse. The auto parts store is closed for the night, so I won't be able to test this out until tomorrow.

Ran continuity tests through all of the necessary wires that would allow it to start, all checked out good.

No guess'*, clue'*, etc...?

How did you determine it'* not a VATs issue? It sounds like you got just about everythign changed. Have you tried a different key?

I was able to get into the program mode to add another key.

That, and I used to do alarm/keyless/remote starter installs as a job. I have a few things that I know to look for.

What did you do to the car just prior to it not running?

Ran a few errands. Drove 25 miles out to work on my Firebird, then 25 miles back. Parked the car, then ran a few errands a few hours later (about 3-5 miles, quick trips around town, several cycles of the ignition for stops at different stores). Came home, parked the car, and went inside.

My last attempt at trying to figure this this out is I'm going to inspect the ignition harness at the cylinder. I mean, I can hear the pump run, all accessories turn on, etc... but it will only take me a few minutes to do, so it can't hurt.

I'm kind of stumped on this one. All I can say is test the crank sensor. Don't recall which wires it is but as it turns you will get a on off on off of the sensor. I would concentrate around the crank sensor, cam sensor, and ICM.

Maybe an engine ground came loose. This is odd. If you have power to everything, and it still doesn't start, check grounds.
