  You need to figure out if there is a spark issue, fuel issue, or something else.

  1) what exactly is it doing?  is it cranking and trying to start, meaning battery/electrics seem god, just not starting up?  or is it not cranking either?  or a weak crank? (battery, starter, coil, etc issue?)
  2) try taking out the fuel pump relay and jumping the pins 7&8 with a wire, does the fuel pump hum/spin?  If so, try starting it then.  If still not, try removing air cleaner and pouring some starter fluid in there, see if it starts and dies after you stop pouring fluid in - this indicates fuel issue
  3) check for spark if fuel checks out okay
  4) if all that checks out okay (good spark, fuel, etc) maybe something like crank position sensor?

    I'm new to mbcoupes. My 86 560 stalled out on road and would not restart. Usually this is furl pump relay.  I had one on hand changed and did no good.  Checked overload relay fuse it was good. Checked rotor good.  Any ideas would be appreciated. Thanks, Neville Pearson
