Vehicle listed above is an lxx model. No spark, arkham had the fuel pump replaced because it was stalling going down the road. Replaced the pump still no start. Check for fuel is check for fuel cylinders are flooded. Pulled the plugs no spark. Our pm gauge jumps a little bit when turning over. Have code for throttle position actuator that is on. Already replaced the MAP sensor. Any ideas of what to back trace to test the wiring going to the coils has 5 v. So gas is not the problem. Crank position code no cam code.

Hello,

One of the symptoms of a bad crank position sensor is stalling as you are driving down the road.
Typically the engine will crank but not start.
When a vehicle unable to start due to a bad crank sensor it may or may not trigger the check engine light.

The crank sensor should have 630-770 Ohms or resistance.

You said the check engine light is illuminated. What are the trouble codes that you are getting?

Let me know what you got.
Thank you.

Both of those codes are for the Electronic Throttle Control module.

P2106: ETC System Malfunction - forced limited power
P1295: ETC System Malfunction - power management

They can be triggered for various reasons, from a faulty PCM to the TPS.
I have attached the diagnostics for those codes.

Your crank sensor could be the culprit. Are you getting a crank sensor code?

This is what the crank sensor reads, no magnet and then magnet.

What is the resistance on the crank sensor pins?
It should be 630 - 770 Ohms at 20 degrees C (68 degrees F)
Air Gap .................... 0.5 - 1.5 mm

If it is out of this range that likely a bad sensor.

Just to jump in, in your original post you stated a crank sensor code, and further down you state no codes?

Can you give us the code that was set so we can get a flow chart for you?

Also, if you have a tach on the dash, do you see RPM reading while cranking? If you do, the crank sensor is working.
