Hi, my name is***** will the fuel injectors cause a hard start problem on the SL and they will rarely cause loss of fuel pressure. Loss of fuel pressure is usually going to be caused by a bad accumulator, fuel pump check valve or fuel pressure regulator in the fuel distributor. Hard cold starts are usually caused by a bad warm up regulator. I doubt that replacing the injectors will solve anything.

Let me know if you have any questions.
