Question about 1985 Mercedes-Benz 300
I just replaced the fuel filters they were really dirty, runs on biodiesel i still can't get it to start please help
When you say 'biodiesel' do you mean true bio that is a mixed product or a combination of vege oil/diesel or pure vege oil? What is your daily air temp? Pure vege and even some combos with a high percentage of vege will thicken up in your injector pump, lines and injectors. If you're in a cold climate, I suggest moving the vehicle into a garage (preferrably heated) warm the car up as much as possible, using a tarp and heaters if nescessary. (Don't start a fire!) There also is a bolt on top of the water seperator (looks like a spin on oil filter in front of the engine) that you can loosen while you crank the engine until fuel comes out of the bolt hole. This removes any air trapped in the line. Hopefully you filled the H2O seperator with diesel prior to reinstalling it.Don't forget to add regular diesel to the fuel tank to thin out the vege, if that's where you put it. If you think that the mechanical fuel pump is giving up the ghost, I suggest trying an inline fuel pump from an early '90s Chevy diesel. It's electric and can be placed on the firewall near the inline filter, just bypass the mechanical and give it a battery source that is keyed.
