Hi guys,
Would really appreciate a steer here.
1990 R129 500SL parked up for 2 years. Started a week ago but it was in a small garage and because of fumes it was only run for a few seconds. With hindsight maybe not the smartest…
Won’t start now, just turns over. Battery very strong, immobiliser believed to be ok. Fuel tank drained, new plugs. Nothing.
Getting fuel to the Bosch distributor ok, getting pressure out (x7, one was awkward to reach) of the distributor. Dried plugs, nothing.
How much (old?) fuel sits between the distributor and injectors? Lines look very narrow, can’t be that much...
Forums point to Mass airflow sensor (not sure these early cars have them?) or Crankshaft position sensor? Is the second stage of the fuel relay not happy with something? Are there sensors which don't allow it to stay running versus don't allow it to start running? Fuel and spark and no fire a little odd…but perhaps its a sensor somewhere..
Any assistance greatly appreciated.
Thank you

Note - my R107 and W123s have never given trouble like this !!
