91 300CE suddenly no start

[Gerard]

Hi All,

On saturday I treated Kurt Koupe to some new oil, a new filter, and cleaned his ABS sensors while waiting.

When I had filled the oil I tried to start the engine, but it wouldnt fire. I wonder did I do something inadvertently like disconnect a wire?? The car was running fine up till then. Battery seems good, lots of energy, fuel pump kicked in at ign time. Had a helper check the plug (no. 1) and told me there was no spark. I took off the coil and brought it to work today. The resistance values appear within Merc specs for both primary and secondary.

Any one got any suggestions as to next steps? I have the service CDs and will get a multimeter so I can check the car on Saturday again. (had to go to work and leave it behind....!!) n Thanks
