Shop just installed new longblock now getting code P0335 ohm out sensor it is good. Traced ckp wire up to ecm tested good and good test out of ecm. Could a fuel rail sensor be bad causing long start making ecm throw crankshaft position sensor code?
My car has an automatic transmission.
Hi there. From the description you have provided, I don’t believe a bad fuel rail sensor could cause the ECM (electronic control module)/PCM (powertrain control module) to set a P0335. The crankshaft position sensor could set the P0335 and cause an extended crank. Typically when the sensor fails, the engine is a no start. A misadjusted sensor and/or reluctor ring would be more likely, to cause an extended crank. I have seen a faulty camshaft position sensor set a P0335. Not sure if, your vehicle is equipped with a CMP. Before spending money on replacement parts. I recommend your vehicle’s extended crank be diagnosed and repaired by a certified technician from YourMechanic.
