Late 04 truck early 03 engine swap issue

[DeputyDiesel]

So a few questions on an 2003 engine into a late 2004 truck.

Problem. No start now. White smoke when cranking. Un burnt fuel smoke. Not coolant. Some stumbles but no start.

Obviously there are a few differences. Eg. ICP location. Wiring was successfully redone to the rear location on the 03.

Im using all the 03 sensors and parts as the engine was complete, and all the sensors and parts on the engine are brand new ford parts. With the stock 04 wiring. Is there any difference in some of the sensors??? Crank? Cam? they all plugged in the same.

I have oil pressure. And obviously fuel. And ive never had a truck this hard to start after a rebuild.

Im sure some of you guys have run across this before.

Oh and New FICM from Ford Alternator and batteries.

i know 03 injectors are different. not sure if it would cause it to not run though. when you say you have oil pressure, you mean high side pressure?

I believe that re-Manufactured injectors from 03-07 are the same, 03s have a different oiling system for the high pressure oil in the injectors.

I just got done reading that there are cavities in these motors that don't normally drain during an oil change. Have you checked your oil level? The author of this claimed 18 quarts to get his 6.0 primed to fire. That's 2~3 quarts more than an oil change.

some reman injectors are 03-07. but from the factory, 03 are different. i've always been under the assumption that you can run late injectors in an early engine, so long as they are all replaced. but cannot run early injectors in a late truck. haven't really looked into exactly what is different about them, but i will see what i can find. if even just out of curiosity

The engine was a Ford Canada Reman and came complete. Sensors/Injectors just no turbo or FICM.

I didnt think the injectors would cause an issue as they are 03 and the engine is an 03 with the early style HPOP and system. Hence moving the ICP wiring. From the pass VC 04 style

My thought was maybe some of the sensors were different causing the 04 computer to read incorrectly

Im fairly certain i have high pressure oil although i do not have a scan tool that allows me to verify. How can i be 100% certain with out a scan tool?


Yep she is full of oil. 18L

[kaya@bernhausen]

sorry. my mistake. apparently you can use 03 injectors in a late vehicle. my thoughts were that it might have had something to do with the late ficm and/or pcm being used in conjunction with the early injectors. but never mind that.
you will need a scan tool capable of reading live data to check the icp while cranking.
you can however check the voltage reading at the icp while cranking, using a multimeter. i'm not sure what the should read cranking. i usually just read pressure. probably somewhere around 1.8v..maybe. i'm sure people here have measured through voltage and can chime in though.
all the sensors should be the same.
check your codes. first and foremost

Got the truck fired. It wasnt cranking as fast as I thought it should. A new starter took care of that. a few other things tidied up along the way. But new starter. Fast crank it flashed runs mint.

Starter was probably tired from the alternator and FICM diagnosis Pre me. And 184k

Anyway. This got me thinking what is everyone doing for break in these days. On their new engines.

Lets here your break in procedures.
