Common problem on this engine and the current solution is to constantly change the oil to prevent overflow and then inter your DPF system if you have one.

One thing to try is have your computer re-programmed, but no guarantee it will solve your problem.

SOURCE: 85 s-10 2.5l no fuel from the injectors

electronic engine control unit calculates the mass of fuel to inject, not how wide it sprays. It's the type of solenoid that you use. Some have wider spray nzzles than others. An external Fuel pump helps the delivery of the fuel. Also since fuel injectors rely on mass air flows nowadays, you have to have proper mixture coming through. hows your Fuel pressure regulator?

The throttle position sensor reports to the computer the position of the throttle butterfly valve, which the ECM uses to calculate the load upon the engine-but inorder for this to run, you may need an external pump.

Sounds like nothing is being grounded back to the ECM to even give a reading. If your regulator is improper and you do not have a external pump (depending on your model), than check those. If not, Start from scratch.

If you ever lose your way, go back to the beginning_REWIRE!

Goodluck.

2000 peterbilt. Why no power on hills?


diesel engines that has a power loss , (1) ck you fuel filters fuel pumps and make sure its getting all the fuel pressure , sometimes the lift pump goes and its runs only on the injector pump (but with no power ) second ck your air intake filters , ck your intake hoses , follow it all the way thru the turbo to the intake , look for cracks in flex connectors and missing clamps

also if your needing a pulling truck id look for a slightly larger engine for this one , as I do belive this engines only rated for about 312 hp and that's at about 22oo rpm !

this engine is common to find in medium sized earth moving equipment

I have a 1999 dodge cummins 1500. While changing oil last weekend, i noticed i had a large amount of diesel fuel in the crank case. does this sound like a injector pump problem? it has 190000 miles on the...


How much is a "large amount"? And how long has it been since your last oil change? It is normal for a diesel engine to have fuel in the crankcase due to the high compression ratio. I believe if there is less than a liter (quart) after 4,000 miles then you have nothing to worry about. If it is more then I would suggest you have it inspected for leaking injectors.

We have a 3.2 DiD Misubishi Pajero and I think the injector pump is playing up. The car has just started surge and run rough and then starts to smoke like to much diesel is getting into the motor white...


You generally only get white fuel smoke from a diesel when one or more cylinders aren't firing. If it were injecting more fuel than can be burned into a cylinder that is firing you'd get black smoke. You can get gray smoke from a cylinder that is firing cold or late, but blue obnoxious smoke is more common with late injector pump timing. Dirty/failed injectors also generally make a rude blue smoke.

Run a can of Diesel Kleen through it. If you can't get it where you are call a local truck service and ask what they recommend for cleaning the pump.

Check and keep watch on the oil and coolant- white smoke from a warmed up diesel is usually coolant that is getting into the combustion chamber, typically from a failed head gasket or cracked head/block.

If you see any oil floating on the surface of the coolant, or if the oil starts to look milky, this motor must be serviced and the issue found or it won't last long.
