Car won't start

You take the crank sensor connector loose from ignition module. Do an ohms test on the wiring terminals to the crank sensors.

If that checks out, with everything plugged into the ignition module. Turn the key on, at the ignition module, purple wire with white tracer is the 4x signal, should be 5 volts. The lite blue wire with black tracer is 24x signal, 5 volts.

Then, engine cranking, the 4x signal may go to 1.5--2volts. The 24x signal stays around 5 volts.

Off idle, open the throttle, how does it sound? You may need to clean the idle air control valve and passages. You could have a vacuum leak? Other than idle, is it driveable?

Take the throttle linkage loose, any difference? Block off the mouth of the throttle-body, any effect on the idle, that should kill it.

Check the tps and iac.

How did you get spark back?

Look for an idle air control motor. If you answered some of my questions, it might help a little?

Good catch.

I guess I'd have to look at it? If you block the air inlet, it shouldn't run, It has to have air. Does inlet air go to the mouth of throttle-body? If air inlet goes elsewhere, block it.

With engine off, unplug idle air motor. Start engine, idle any different? I'm about out of ideas?

Does the inlet air go to the throttle-body or elsewhere? I'm talking about the air inlet from the air filter, block it off. Did you unplug the idle air motor? Unplug the throttle positioner sensor. Do these one at a time with engine off, then start.

If the engine isn't getting air, it can't run. It's getting air from somewhere.

That is a knock sensor code. I don't think that will cause high-idle. I'd have to put a scanner on it, that will show live engine data, try to see what's going on.

You could try tapping the block close to knock sensor, see if any effect on idle?

I've seen faulty cruise controls go crazy and the rpms would hit the roof. If you had everything disconnected from throttle-body, that shouldn't be an issue.
