Help Just Changed CPS
Okay scanned my 07 c 230 came back with code p0336 for the cps. Changed it out 15 minute job. Scanned it again still the same code. Here's the problem when you start the car it will continue to try and start when you let key go. It still is doing it even after I changed the cps. Could I have gotten a bad cps from the store?

These cars have a crank 'till start feature.
If you cleared the code & it comes back again you might have a second bad CPS. It happens. Is the CPS properly connected?
You need to check start enable fuses 31,52 & 57. 52 will be OK because she cranks over.

P0336 means that the performance of the sensor is out of range. This can happen when the wrong sensor is used.
I just replaced mine. The original went open circuit and threw P0335. I bought an AB Electronic (Hella) unit and it had a DC resistance of 700 ohms. My engine is a M112.
I would check the EPC by VIN and determine the correct part number. Then compare that with the one in your car, then check that the DC resistance is nearly the same for the new unit. Did you buy genuine OEM, or another brand?
Other problems that may cause a no start should be considered after P0336 has been cleared.

Fuel, spark, spark at the right time, air are required. Read codes with an OBDII scanner.
Check.
CPS (crankshaft position sensor)
Coil packs & plug wires,
Air filter & that airbox is clipped down tightly over the MAF
Fuel pressure at the front rail should be 3.8 bar or 55 psi while cranking. Check at Schrader valve.
Fuel filter
Start enable fuses 31, 52 & 57
Good luck.
