Hi all new here and new with A Benz, just inherited the 380 16K miles wife pull in to fill up with gas and car would not start. Turns over great but will not fire.I need all the help and advise you can give this newbe. The way my luck has been running it will most likely be the highest $$ part(s).

Hi there,
Do you have spark? Pull the wire off the center of the distributor and connect it to a spare spark plug, turn the engine over and look for spark... If no spark, you've isolated it to the ignition system. If you have spark, check for fuel! Perhaps the easiest way is to slightly loosen one of the fuel lines at the warm-up regulator, turn the ignition on for a few seconds and look to see if fuel ran out. If you have fuel and spark, do they occur at the correct time? (could be broken or jumped timing chain) If no fuel, check to see if the fuel pump is running. If not, check the fuse on the relay. Could be the fuel pump wore out, or the fuse is blown, or the relay is bad...

Good luck with it,
Richard Wooldridge

Just thought of another possibility - are you sure she put gasoline in it and not diesel??

Yes it was gas she put in it. I checked the car it has fuel psi no fire to the plugs. Any ideas where what and how to check next?
