Engine rev at one speed

On this Mercedes Benz 814 truck, fitted with a OM904LA engine, the engine starts easily but only runs at 3000rpm. Absolutely no throttle response. So far I have replaced the ECU, FMR and the throttle position sensor. Please can somebody help me?

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

SOURCE: No spark, 1988 Toyota Camry 3SFE 4cyl, 5 speed.

there is no crank sensor on this vehicles 2.0L. If you have power to the coil, new coil, cap and rotor try this if not done yet>>>Unplug coil power first....Try pulling off the distributor cap, and make sure the rotor is spinning with the cam...If this fails to spin, inspect the entire distributor assembly. If it passes, Inspect all the power circuit and wiring to the dist assembly, if ok possible ecu. i recommend having a mechanic check it out!! Hopefully this helps...please rate...thanks

Whistling noise when i rev my mercedes c 220 cdi 2004 plat


If the engine is a diesel that is equipped with a turbocharger, I would look for a pressured air leak at any and all hose connections. Especially when the engine is running at accelerated speeds which cause the turbo to operate as a charger.
Check any and all belts for slipping, Alternator, P/S,etc.,

Loss of power


I have the same problem on a s320 cdi, gearbox goes into limp mode and wont rev above or kickdown, at the 1st chance i get to stop i put into park or neutral gear turn off the engine and re-start and then everthing is fine, I read that if you put a new battery on it may solve the problem, it's something to do with the voltage dropping below 10.4 volts. Then it sends a message to e.c.u. that puts your gearbox into limp mode. Hope this will work for you. MERKY

Too fast idle running speed.


Typical idle for this motor is right around the amount you have described. Check to see if any check engine lights are on, or if the ABS light is on. A typical issue with this motor is the OVP relay that when not operating properly causes the engine to rev much too high (~1500-2000). Also do your revs drop significantly when you put the car into gear? If not then there really isnt an issue. When the motor is idling too high and you stick it into gear the car will typically lurch really hard.
