Question about 2004 Dodge Ram 2500

1 Answer

2004 dodge diesel

I replaced the engine in my customers truck and now it will not crank.All i did was just swap the engine out.Used the wiring harness that was already on the motor.Both engines ran prior to removal.Once installed the only way it will crank is if i turn the switch key on and off real fast for 4 times.Then on the cluster where the milage is it will read done then the engine will run for 3 seconds and go dead.Repeat the procedure and it will run again.
Does anyone have any clues?

Did you use the existing ecm or the one that came on the new motor. probably need to program the wcm. transfer secret key also. sounds like the problem to me. if the vin number in the ecm/pcm/wcm dont match the truck wont stay running

Can i put gas engine in 83 f350 which had 6.9 diesel


problems that can be encountered is the bell housing bolt pattern and size, engine mount positions
ECM and wiring harness and sensors
fuel tank venting is different
most vehicles running diesel engines have a higher diff ratio to compensate for the lower max rpms of a diesel engine
you may have to put the heavier suspension in as well to compensate for the heavier engine
I t will be a good project as long as you are aware that it is not s straight swap

How many volts to a speeed sensor


what country?????????????????????????
why does WIKI say Tucson started in 2004????????????? above
your post shows 2002, why?
what size Diesel there are 2. 1.7L and 2.0L.
in 2009 2 more diesels , amazing huh, with no year or engine stated.
what exact engine, need exact. year, 04? and what engine diesel.
The reason is , the EFI injector systems and sensor very on all engines.. and for sure on diesels.and for sure for EUROPE.

took out PCM. ah its a swap.
ok which speed sensor, there are up to 4 or more on cars now.
2 in the A/T is yours A/T or M/T , car has BOTH OPTIONS>
2 in the engine. (crank /cam)
I cant guess this. who can, nobody, right?
but i can tell you there are 2 types.
MAG ( 2wire)
HALL. 3 or 4 wires.

2 wire needs scope to see the vary fast 1volt pulses.
Hall sensors usually have.:
pin 1 (random guess #) 5v
pin 2 output
pin 3 ground, some have 2 ground.

There may be some sensor that have 12v pins.
but id need to know EXACTLY what engine, EFI and country.
ive ask like 100s of time on this forum and not ever one answer.
ah ,its an engine swap.why not say
removed my gas engine and put in a diesel.
are both engines USA engines? what?

you do know gas sensors and EFI are totally different right.?
is this your new engine
2.0L CRDI I4 diesel

state side our cars are all OBD2 and all will tell you (SCANNED)
and cranked, which sensor fails. ever scan a car ?????
it will throw a DTC code after any 5 second cranking,
release key,not off and LOOK there, see those codes, BAM !

look here , see them all
see what you car might have and the donor, car,
the donor car was UNSTATED TOO.

CAN YOU REPLACE A 1995 GEO TRACKER ENGINE WITH A TRACKER ENGINE WITH A CRANK SHAFT SENSOR???


what years? her ill give examples (no 1.8L sports)
in each case keeping original in/exh manifold of origional
this is called, a Long block swap......!
96 to 95 16v ok ( the crank sensor just sets there, doing zip)
96 to 95 8v no go. ( it will run by ECU while have fuel mapping)
95 8v to 96 16v no go ( missing crank sensor and mapping issues)
95v 16v to 96 16v,(missing crank sensor, move it.)

and you can swap any with harness and ecu. and manifolds.

see swaps here

Hi :) Check the wiring harness for a fuel pump relay that is on the firewall. The trans is computer controlled (shift points, firmness, ect). You would either need to run a TBI motor from a '92-95 3-4 or 1-ton truck and get the computer to go with it. Then the new gas computer can run the trans. You will also need to swap the torque converter to a gas unit instead of the diesel. OR get whatever motor you want, and then use a stand-alone controller for the trans. They cost about $600+ for the controller. Still need to do the torque converter. You could run the diesel TC but it just wouldn't perform to full potential.It will bolt up, but a diesel transmission is different from a gas transmission. Diesels shift way earlier and only go to 3500 rpm max. If yo u do the engine swap, you will need a new valve body in the transmission. I have a 700R4 in a 1935 Ford truck. It never shifted right unless I drove it manually. It always bogged down. I took the transmission to 5 different shops and no one could figure it out. After 6 years, I was telling a buddy about it and he had me bring it to his shop. He changed the valve body (was a diesel trans and I didn't know when I bought it at an auto swap) to a corvette valve body and now the truck runs great.

Can i change my automatic transmission to a standard transmission in my early model 2004 dodge ram 2500 diesel


The short answer is no

the list of replacement parts would most likely exceed $8000, trans, trans control module, engine control modules, complete engine & trans wiring harness, trans, modifacation to the firewall, complete pedal assemblies, and the complete engines were different if look at the specs at dodge.com

Motor swap now it will not start


Unfortunately, there is no easy solution here. I had the same problem with my race car. I swapped a 96 2.2 into my 97 racecar and ended up having to also swap the engine wiring harness, computer, instrament cluster and pass module. The engine harness will bolt to the interior harness even though the wire colors are not the same. Just make sure you match the large yellow wire on the 96 harness to the large purple wire on the 97 harness. It sounds pretty complicated but it only took me maybe an hour to perform the swap. Now I'm back up and running and will be racing again this weekend.
