It is doubtful that a fuse has caused the engine malfunction light to come on. The 3 fuses you described are for Body, Accessory, and Ignition.
I recommend either borrowing or purchasing a cheap OBD II code reader to determine the OBD error code as that is the only way to know what has caused the IML to turn on and properly diagnose/fix the issue. Good luck!
I don't know for sure but I think the ECU will need programming with the vin-sensitive security code(s) and possibly other information that is exclusive to your car.
The so-called flashing is used to instal software patches and fixes in service when problems are encountered. Unless you are unlucky a new or official replacement ECU should already be loaded with the latest software version, but again the dealer should be your first port of call to ask such questions and then maybe compare notes and prices with a few local specialists..
I suggest you check with the dealer and ask if the part number has been superceded, or if the unit has been modified in the last ten years.
If there are no changes to the spec, the replacement ECU should have exactly the same part number as the original.
Lack of fuel.
Boost hose off or split.
ECU detected Over Boost and engine now in default.
Do you get normal power after restart? If so, ECU is limiting power as it has detected a problem. Need scanner to determin what code/s has been set in ECU.
The boost hose under the engine on the right side
where it goes to the turbo has a habit of coming apart at the clip .
do a compression check your guy could be wrong .. if you got compression.. pressure test fuel then reflash your ecu could be wrong set up for your truck sounds like ecu problems these are programed off your vin if not for your truck it wont work must reset everytime
Have you have the replacement starter and ecu coded to the car? You need to have the vehicle connected to a star diagnostics system to determine the fault.
First thing to determine is if your ecu module ,has the same hardware,software references as your original ecu.If this is the case,and you havent changed anything else,like keys or ignition switch or immobilizer,then it should start!
If ecu doest have same references,you need to have it coded by the dealer,so that it works with your immobilizer.
They are electronically controlled, normally monitored by the ecu by the temperature sensor. They come on when the ecu determines the temperature to exceed the cooling capabilities of the coolant. usually about 190-200 degrees.
At the ECU there is a connector that you use standard analog volt meter. In using the twio proper PIN connections the ECU will give yoy a type of Morse code to determine engine and sensor errors
If you like I can email you these codes.

There is a problem with the emissions system, an the ECU has set a fault code. The ECU will have to be scanned. The fault code you retrieve will help in determining what the problem is.
HI the (MAP) sensor is one of (ECU) engine control unit sensors it was determine the engine manifold pressure and send it as electrical signal to the (ECU) to calculate the air volume & fuel injection to the engine
