Any idea if the EWS, transponder and EMS2000 were from a 190 Matt? failing that, send me the original EWS and I'll programme a transponder for you

It's not a question of insufficient fuel Matt (you're thinking of the diesels' problem). You need to check that the two halves of the fuel filter are absolutely tight and whether the orange clip has been fitted. If the filter has loosened, even slightly, fuel pressure will be low and the engine won't start.

However, MarinaBrian will be able to tell you whether your replacement ECUs need 'programming' to match your car.

Same numbers as in NNN000170 Matt, what were the NNW (tune assembly numbers) on the white label bearing the VIN?

Probably a long shot but check fuse no3 (15amp, camshaft and oxygen sensors) in the engine compartment fusebox. It fooled me once, it appeared that one of the oxygen sensor wires had shorted on the exhaust heatshield. It's something simple to rule out if nothing else!

Give it a squirt of easy start, if it tries to start you will know it is fuel or spark.
