What is the purpose of this module & how can I tell it’s bad?
I have no spark to all 4 coils
Thanks Everyone

NATS and its part wiring (kinda) and mostly ecu IIRC, works with the ignition signal and key. Don't know how to test as I don't have NATS. You can't replace the ignition switch alone but testing it would be your first start unless your key is having issues.

Search for the FSM link if you want to dig into yourself.

I haven’t checked the ignition relay behind the fuse box
Has anyone ever taken the box out to replace it?

It pops out easily.

I’ve tried to no avail
Are there clips to pop?
Thanks Dude

Bad images but on the outside of the block is the T tab looking things, acts like a plug all around it.

I purchased a little LED light tester and it does flash green once I turn the key, so I’m assuming the immobilizer is not the issue?

Does it crank at all?

Yes, it does nice and strong

Check your cam position sensor, if that's bad it won't send a signal for the coil packs... should be throwing a code.

I just replaced cam & crank sensors & it still gives the cam code

Timing is off, will have to tdc the motor and reset the intake cam. This will cause a no start as well.

I did a new timing kit on it myself & everything was set TDC
When i got the car back it wouldn't fire up but prior to that it was only running on 3 cylinders so maybe ECM was on the way out?
