Codes c0755 p0300
SOURCE: trouble codes p0201
Start with the replacement of the Crankshaft position sensor to address the P0336.
The faulty crankshaft position sensor may be causing the P0201 which is a fuel injector failure to injector #1 and the P0203 which is a injector failure to the injector #3. The failure to the injector will cause the P0300 DTC code which is a code for multiple misfire.
The crankshaft sensor sends signals to the ECM which then would command the injector to pules open and close and the duration of time. If the ECM does not get the right readings, then it's not going to know when to command the injectors to activate.
Start with the Crankshaft sensor (CKP)and then check the injector wires and injectors it self after the (CKP) has been replaced if problem still persists. Good luck and keep me posted, be glad to help you get your car running 100% again soon.
SOURCE: How do you clear trouble codes on a 94 GM 6.5
Take it to autozone or a major auto supply house and have them use the fault code reader to read it for you, they usually do this for free and will tell you what the error codes are if it is something simple it can possibly be repaired right there and if not you need to take it to a mechanic. Disconnecting the battery will not clear a fault if the fault still exists.
I hope this helps you with your issue.

P1441 CHEVROLET - Evaporative Emission (EVAP) System Flow During Non-Purge
P0300 - Cylinder Misfire Detected Random Cylinders
Possible causes- Faulty spark plug 1
- Faulty ignition coils
- Ignition coils harness is open or shorted
- Ignition coils poor electrical connection
- Clogged or faulty fuel injectors
- Injectors harness is open or shorted
- Injectors poor electrical connection
- Improper spark plugs
- Insufficient cylinders compression
- Incorrect fuel pressure
- Intake air leak
if you noticed that the closes relation those two have to each other has to do with a leak possible vacuum leak. look for hoses or grommets that are very soft, loose, cut or disconnected. the other code P1870 pertains to a transmission component slipping you should not need that for a smog check to pass

Engine is running rich--may be the cause of the misfire code as well. Couple things to try. First, clean the MAF sensor by spraying with electrical parts cleaner. Also, try adding some injector cleaner to the tank.
