Re: 2004 sprinter Black smoke
Assume diesel engine ? so if water was in fuel ? the engine would not run even b4 it got to engine because fuel filter would rstrict diesel due to water on filter element ? can i just say that from your symptoms ? black smoke/engine runs but poor ? the fact it is black smoke? is most due to lack of air flow to manifold remove air filter element and see if smoke clears? if element of filter has got wet ie floods? it will not allow air through? make sure there is no other restriction/s on filter inlet and outlet pipe to manifold espcially check now for any weakness on pipe to engine from filter ie when you rev up look to see if hose is sucking together due to vacuum created by revs of engine? if injectors were defect ? the smoke would be blue due to over fuel injection ie injectors not atomizing correctly ? i would suspect problem is lack of air? out of curiosity?? how did water enter fuel tank ?? if any more info you can provide it may give better idea of problem ?

black smoke is over fueling and although the turbo appears to spin ok the vale variation actuator may not be operating correctly
there are vanes in the exhaust turbine housing that are altered to increase the exhaust gas flow onto the turbine blades for quicker acceleration and these vanes are operated by a vacuum actuator and rod by a sensor
the vanes are subject to extreme heat and can rust stuck open or the hose gets hard and cracks
s not allowing the vanes to work
I would be concentrating in this area before the EGR valve
run the fault codes as well to get a better idea of the possible fault as some systems only put the light on for extreme conditions in engine and transmission
Egr clap closed - doesn t allow air intake - car also blows black smoke while cranking.
- low pressure fuel pump - located inside the fuel tank - may be burnt
- high pressure fuel pump - engine bay - also may be burnt
- not enough fuel inside the tank
- fuel leaks before reaching injectors
has the check engine light come on?
is it blowing any smoke when it starts and if so what colour?
has its servicing been kept up to date?
could be fuel related
check and drain water trap filter under vehicle look for any water contamination.
have the fuel filters been changed?
is it running rough at idle? these had problems with EGR, injectors, and suction control valves as well as lift pump in fual tank that could cause your concern.
how many KM on clock?
have you looked into the injectors, or injector balance? glow plugs just preheat the cylinders before you start turning the engine over. if the injectors are dumping too much fuel it will run rich and blow black smoke, lean it will dump white smoke, same as if it has an internal coolant leak, but smell different. Ford has had problems with EGR systems on some of their diesels, being an older truck how many miles is on it? and the front fuel tank could have a bad fuel pump, pretty common for them to do what you have described. Also might want to have the timing looked at on it! It ignites off of pressure, and if the timing is off it will adversely affect the ignition of the fuel which will make for hard starts, and poor running. there is a lot that needs to be looked at to figure this one out! could be quite a few different things. Good luck!
You may not have all the things I list. these are things that will make an engine run rich. ECM, 02 sensors, map sensor, mass air flow sensor, vacuum leaks, throttle position sensor, Clogged air filter, Clogged catalitic converter. You have already replaced the injectors and the ECT , so that rules them out. Check for codes. Start with vacuum leaks. Hoses and the intake manifold gaskets. If you need more info let me know. Randy
A bad coolant temp sensor for the ECM will cause that problem ... they are cheap and easy to replace. One other possibility is a piece of carbon stuck in the EGR causing an internal vacuum leak .. Good luck.
YOU HAVE A AIR LEAK IN THE TURBO SYSTEM CK HOSE'S MY 2006 3500 SPLIT THE HOSE HIGH WHISTLING SOUND. LOW POWER / AND LIMP MODES TOO. ORDER THIS AND BINGO IF FIX IT . YES THE OLD TURBO RESONATOR HAD SPLIT TOO. I did not use the o-ring from the old part I found one 1 side down that fit tight around the new part. A loose o-ring is going to weak air too. Got mine on ebay.
THE SPRINTER TURBO RESONATOR ELIMINATOR For your late 2004 through early 2007, 2.7 liter 5 cylinder in-line turbo diesel engine, our billet aluminum SRE-06 Turbo Resonator Eliminator completely eliminates turbo resonator failures forever.
The SPRINTER TURBO HOSE ADAPTORS FOR CRACKED HOSES Completely eliminates turbo hoses cracking and blowing apart at the metal end.
For your 2002 through early 2007, 2.7 liter 5 Cyl. Inline engine, our ADAP-06 billet aluminum fitting with rounded ends, completely eliminates turbo intake hose from cracking and blowing apart at the metal end.
First of all,did you replace any tire in your car? if so,make sure they all are the same,otherwise those lights will light up,make sure all the abs,sensors are clean,some times they pick up dirt,and that's enough to turn those lights it may be also a wiring problem did they check that? let me know...good luck
Sounds like the injector pump has lots of miles and wear or it has lost its calibration; but before jumping to that conclusion, you should replace the fuel filters first to make certain that the engine is not starved for fuel....when you replace the fuel filter, observer whether there is any water inside it by blowing through one side to see the results... if there is, you likely have more in your tank and it should expelled by draining or removing the tank and cleaning.... There is also a course filter in the tank that could also get clogged.... while you have the fuel filter off you can blow air through the filter port back to the tank and loosen the stuff on the filter... mind you know that this is a temporary fix for trash in the fueltank. Now when you prepare to replace the fuel filter(external) you must follow the procedures for expelling air from the line and filter prior to tightening the fittings. I like to remove the glow plugs(if you have them) to freeup the compression to expell the air any time the fuel lines are opened..This will save your batteries. Your engine will not run until you get all the air out of the fuel lines. ' If the fuel injector pump is out of calibration, it will have to be removed and bench calibrated after a bebuild job.
