My man truck is having this problem as soon as I start the engine it gives error 3780-01 and engine light is displayed engine looses power. Please help.
Its probably trying to tell you there's something wrong with the engine? Some ECU controlled engines go to a soft power mode to limp along with. Search for a manual or contact a dealer. I presume you have done all the engine checks?
Testimonial: "thanks, i have replaced the metasuring unit, rail pressure sensor, rail pressure limiter but problem still persists. kindly advice me on further checks to be carried out."

Like to other guy said, give it a tuneup. Also try SEAFOAM to clean carb up of slug. Also check to make sure the butter fly for the choke has not come loose, causing it the choke it down. Failed choke pull-off.

Well this is an oldie, but your code is cylinder head overtemperature protection active. countrycurt0

you might try unhooking the battiey for 20min both + and - posties cuz that will force the computor to have to resest only if you have addressied the fuel pressure problem which taht would most likly be your filter which isn't all that much

Hi Adil, I'm sorry you haven't traced the problem but what you need is a dealer or truck specialist that can get the codes sorted out. It may cost you to have the code read but save time and money in the long run by not putting costly parts on at random hoping to fix it. 5 mins with a code reader could lead to something broken or hanging off thats a quick fix?
Check Rail pressure & Valves...!
maybe ur fuel injectors are compensating too much or leaking too much fuel to the combustion chamber without burning the fuel
