The crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

I change the front valve cover gasket, afterwards I proceeded to start the car and it wouldn't start but it still cranks, the codes are o2sensor codes, every injector circuit open code, turbo code, and last an evaporate code. I've change the ignition control module and the wire and the crank position sensor still the same results
I had to replace the crankshaft position sensor
