Hello, I own a 2001 CL600. The engine spins but the car won't start. It has done this in the past but it eventually started. This time it won't. I checked the codes and got the following: P0335 crankshaft circuit malfunction, P0341 camshaft sensor A bank 1 ckt range/perf and P0340 camshaft sensor A bank 1 circuit malfunction. I have replaced both the crankshaft sensor and the camshaft sensor however the car still won't start. When I push the valve stem on the fuel rail a get strong stream of fuel. Is there any way to check to see if the coils are firing short of removing them? Do any of you have any suggestions?

I would guess the reference voltage is getting pulled down. Check all 3 wires for the cam or crank. One should have 5v, then pulsed 5v, and ground.

Thanks for the response. Are you saying that I should check the 3 wires that go into the crankshaft and camshaft position sensor connectors?
