Folks, got an 03 hemi that will turn over but won't start. I have replaced the cam shaft position sensor and pulled the cowl to check for fuel pressure ( no gauge I just pushed on the pin and out she flowed) and the fuel pump is nice and loud when you first turn the key to the start position (whine i guess is right). it acts as though it wants to start for a split second and then just cranks with no sign of firing.

Please help if you have ideas from here or she is getting towed and costing me biggggg.

 

Had similar happen to me, but I was using a spare with no transponder.

 

I just got it to start be holding the throttle to the floor. She smoked like a freight train but finally smoothed out. I shut her off and still doesn't want to start but now engine light is on so maybe I can get a code to check?

 

code is P0113 intake air temperature sensor1 circuit high input?

 

Changed out IAT sensor and she is running smooth as before. Half the parts stores around didn't know what it was. Advanced had it for less than $10. Hope this helps somebody else in the future.
