Rule of thumb is start with the lowest code. I have only replaced one IAT sensor, mostly a bad wire, usually close to the plug. A cheap fix. Next I would check the IPC sensor. Ohm it out. An OL reading, replace it. Also check the plug for power and ground with key on. Next would be the IDM.
Hello I saw your post and figured I would chime in as the year of your truck is one of the many years that the Ford Diesel ECU and IDM (injector driver module) Go bad then fail completely. On a 2001 I would lean more towards the IDM possibly having a fault especially if you are having hard starts when cold, lack of power, bad fuel economy, etc. I hope this helps in some way. If you need further assistance on this vehicle or any other vehicle feel free to post on here or give me a call. My name is Tim and my company is called AutoEcu1. Fixya along with myself are more then happy for help you with anything that could save you time and/or money. At AutoEcu1 we rebuild a variety of Engine computers ecu ecm transmission computers tcu tcm Anti lock brake modules abs ebcm climate controllers dash clusters and so much more. Thank you for your time, Have a great day!

The p0113 code is probably the start of the problem. This Code is saying that the intake air temperature is high. The Code 1248 is showing you have NO turbo-boost and this can mean that the Turbo is either backed up or has been neutralized to get the intake temperature to cool down. The Code 1211 is for high/low fuel injector pressure and the Code 1212 is a redundant injector pressure warning saying there is a problem.
Another site you might go to is "aboutautomobile.com". You will see Complaints of problems for your exact type of vehicle. It shows recalls and TSB's for various problems.
I do not know the cost of the intake temperature sensor. Also a rich exhaust fuel discharge could burn hotter in the cylinder than normal exhaust. The crankshaft sensor can adjust fuel pressure and if it miscounts the rpm, it can reset the fuel pressure either higher or lower and still not flag a warning for the crankshaft sensor.
Weigh your costs of trying a intake air sensor, crankshaft sensor, etc versus a super scan at a Dealer.

you should probably check your fuel pressure between the pump and the fuel bowl. my bet is that is is dropping pressure to zero causeing it to shut off just after it gets running. and there are several things that could cause that but the first to check is a return line valve on the side of the fuel bowl. that when pressure builds up it releases back into the tank and if it gets stuck open you will not have enough fuel pressure to run your truck. mine just did the same thing.

Hi
Im not 100% here but will give you something to look into. Does the car have a EGR valve?
Secondly check the air mass sensor this could cause multiple codes and make the car splutter.
Is it a diesel? or petrol? if diesel it may have air in the fuel system or a faulty pump. when you done the head did you change the fuel filter, and bleed the system though? only if diesel!, and check the injectors are not leaking, poor water on to each and see if any air bubbles come up. again only if diesel.
Please get back to me if your unsure of anything
