Hard to start would likely be the P01316 which is Injector Driver Module.

Following are typical causes.

Faulty Injector Driver Module (IDM) Relay
Faulty Injector Driver Module
Injector Driver Module harness is open or shorted
Injector Driver Module circuit poor electrical connection
Faulty Powertrain Control Module (PCM)

If the transmission errors occurred at or near the same time, I'd be concerned about harness damage... farm truck?... look for signs of rodents.

2006 sebring touring Error codes
I would start with the fluid level and condition. 731 & 732 are improper gear ratio for first and second gear. 720 is faulty output speed sensor, which makes sense with improper gear ratios.

P1316 means that the Injector Driver Module has stored codes. Most likely problem related to that code involves the wire harness for the glow plugs and injectors under one of the valve covers.

2002 ford f450 7.3 diesel runs ruff and has trouble code p1316 any ideas
P1316 Injector Circuit/IDM Codes Detected .....FJ9 DIAGNOSTIC TROUBLE CODE (DTC) P1316 INDICATES THAT CODES ARE STORED IN THE IDM
Possible causes:
Injector(s) or circuit(s)
Open or shorted IDM enable circuit
Open/short in EF circuit
Open/short in FDCS circuit
IDM relay
IDM powering circuits
IDM
PCM
Check for other codes.
Key on, engine off.
Perform KOEO On-Demand Self Test.

This tells me that the IDM DOES store codes.
Trying to make sense of this. Which test will then give me the codes stored in the IDM? I am pretty sure we did the self test and did not get additional codes

Check engine light with following codes p 1529 p0720 p0715
P1529 indicates that your TCM asked the ECM to turn on the check engine lamp.

The range switch and the output speed sensors are the items that are abnormally affecting the operation of the transmission. The diagnostic logic in your computer can distinguish these issues from one another, so you'll definitely want to do both. You have no diagnostic code for the input speed sensor (P0715) listed, so I have made no recommendation to replace it. In my opinion, it's not a labor-intensive repair, so I wouldn't recommend replacing it unless you have reason to believe it's bad.

DTC - P0720 (OUTPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0720 Output shaft speed sensor system
If the output from the output shaft speed sensor is continuously 50% lower than the vehicle speed for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, it is judged to be an open circuit or short-circuit in the output shaft speed sensor and diagnostic trouble code No. P0720 is output. If diagnostic trouble code No. P0720 is output four times, the transmission is locked into 3rd gear or 2rid gear as a fail-safe measure.
Probable cause
Malfunction of the output shaft speed sensor
Malfunction of the transfer drive gear or driven gear
Malfunction of connector
Malfunction of the TCM

DTC - P0715 (INPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0715 input shaft speed sensor system
If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged to be an open circuit or short-circuit in the input shaft speed sensor and diagnostic trouble code No. P0715 is output. If diagnostic trouble code P0715 is output four times, the transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.
Probable cause
Malfunction of the input shaft speed sensor
Malfunction of the underdrive clutch retainer
Malfunction of connector
Malfunction of the TCM

Is needed replace.
