Hi again all.
I've been loggin on and following the multiple starting issues on this forum with interest, now that the cold/wet season in the UK as starting.
Unfortunately, my diesel mb now has an issue, or maybe just a hiccup.....
At motorway type speeds I was getting poor throttle response, and occasional coughs from the engine. Having read similar experiences on here, I've set to and replaced the main fuel filter. Sure enough the filter was full of bits and generally in a bad state. When I bought the car not so long ago it was obvious from the smell when running that the former owner had been running it on biodiesel or vegi oil, so my thoughts are the crap in the filter is the legacy from this.
So now I have a car with a fresh fuel filter.......but it won't start!?
I've been careful to drag fresh fuel from the tank, and don't think I have an air lock from tank to filter.
However, from bad Vauxhall diesel experiences I'm feeling something is coming back to haunt me......
Has the diesel injection pump died? How strong are they? The GM pumps were renowned not to be strong enough for the vegi fans, but much has been aired on how good MB cars are with alternative fuels. I'd rather run mine on straight diesel, particularly as it looks unmodified, but worried that the history of the previous owner running the car on potentially hi viscosity bio/vegi oil has damaged something, and over time of vegi abuse it's finally given up?
I would value some experience and thoughts? and pointers to get the car started!
thanks
