My mercedes is a 1998 ml320 it ran out of gas in the yard it is slightly tilted down in the front put gas in got a new battery but it want start what could it be have this happen to anyone else


You may have burned out the electric fuel pump, here is why.

The fuel pump is located inside the fuel tank, it sits in the gas and that is what cools the tiny pump and what lubricates it, so if you ride around very low on fuel or run out of gas this can destroy the pump very quickly. Check you fuel pressure at the engine test port located on the top of the engine on the injector supply pipe most likely, I will bet you have no pressure.

Ran out of diesel, when topped up, it still


air in the lines is exactly whats wrong with it but if it is a newer mercedes it MIGHT not have a manual pump and instead have an electric fuel pump if this is the case toggle the key from off to on position "but DONT crank the engine" waiting about 5 seconds in the on position for about 10 tries the crank the engine for no more than 15 seconds. also note that if it does have an electric fuel pump you will be able to hear a faint hum from under the car while having the key on the on position.

Old j reg mercedes 230te wont start


Check Injectors spraying Fuel when you start. Fuel pump prime because you hear the pump. IF pump is weak, then your Fuel distributor doesn't have correct pressure to spray fuel when injectors open. Do your sparks plug wet after trying several times. If they are dry then you don't have fuel. Replace injectors If they are wet then you don't have correct air:gas ratio of 14.6:1. Replace Fuel distributors

Wont start when hot!


hello there, wow my dream p-up. nissan pathfinder 4x4,  unfortunately i have to settle with my nissan navara truck. anyways, the possible problems would be the injectors and injection pump. injectors are really direct on the combustion chamber so everytime the engine runs it is severely exposed to very high temperatures. the nozzle tips are the ones very much abused. the injectors have 2 seals. the first one which hugs the body of the injectors which is usually made of hard copper and the 2nd is called the chamber washer which is a stainless steel type concaved washer which serves as the nozzle tip seal and heat nozzle tip heat dispenser. if the nozzle tip floats there is a tendency that the tips are flame red due to heat thus, diesel is boiling to the point of turning to vapors enough to push the remaining fuel back to the injection pump when you shut the engine. then the one way valves of the injection pump comes into play. the valves might be weak and due to the high pressure, fuel slowly creeps back into the pump body. hope this helps.
