2007 Jeep Grand Cherokee, 3.7 l v-6 hard starting when warm. coils changed, now considering new tipm, fuel pump, key and ignition harness (on recall but no parts in dealership till 9/15, crank position sensor, anything else?
I would expect a sensor problem. You would need a scanner with live data, to check the different sensor outputs when hot. A bad coolant sensor could cause hard starting for example.
The crank sensor is indeed also one which gives problems when hot.
