Mitsubishi 4X4 2005 Diesel rev counter not working

I am not familiar with this model but petrol engines usually use a signal from the ignition system for the rev counter and diesels need a special sensor. However the rev counter is almost certainly unsuitable because petrol engines tend to rev much higher than diesels.

the tachometer ( rev counter) get its impulses from the ignition system or in the case of a diesel from the crankshaft position sensor
if it runs with introduced fuel ( dangerous for a diesel) but then dies, that indicates insufficient fuel pressure to the injectors
could be a diesel pressure pump ( test to 25,000 psi) not producing sufficient pressure to work injectors
problem fuel supply to pump, tank venting, filters , air in system etc

diesel motor parts and petrol motor parts are not rely compatible ether use diesel to diesel and petrol with petrol

Whens the last time you change your fuel filter. The other problem could be the fuel pump. Our you using Bio Diesel or regular Diesel ?
Some Bio Diesel will not burn hot enough to give you the power.

We do not have that type of tech material here. Sorry.

Hi Peter,

With such high revving engines (me being a Honda fanatic) you need to keep an eye on oil levels. Check the level, top up as necessary. Without the correct amount of oil in, the oil pressure cannot stimulate the switch over cam, which takes it to 8500rpm.

Also, please don't rev you car without load (ie. standing still), this causes valve lash and is detrimental to the engine. Again, please do not rev your car hard without letting the oil get up to temperature or it won't last long :)

Once you check your oil, reset the ECU by pulling the battery lead off for around 20 minutes.

Good luck and have a blast. Could you vote for me if this helps you. Thanks.

check your alternator

Possible defective speedo needle stepper motor. This is the little electric motor that moves the speedo needle and turns the mileage counter.

hard starting in the moning if your engine is diesel check your heater plugs means when the diesel engine is cold it needs to heat up, also injection pump and injectors can cause.check the engine compretion.
the petrol engine when your sparkplugs is worn out it can be or when the cyliner head valves is leaking puting more petrol on the combustion chamber.
