I hope someone on here can help me i have a 97 camaro ss . It all started 3 weeks ago when my Check engin light came on code "P0336" Crankshaft postion sensor A, circuit range/performance. I ignored it for a few days till everytime i tried to earse the code it kept coming back. I went to autozone bought a new one and it kept doing the same thing, So i thought it was a bad sensor so exchanged it for a new one till last WEDNESDAY driving home the car was acting up and when i pulled into my neighborhood about 3/4 a mile from my house the car just died while driving. Im not a mechanic so i wasnt sure what it was. I do know its not the BATTERY, ALTERNATOR, STARTER. Yesterday I bought a new CRANKSHAFT POSITION SENSOR from NAPA I check everything i could with my eyes on the engine yestury put the new sensor in and the car STILL WONT START.... it cranks and seems like theres power but it wont start... I NEED HELP BIG TIME..... does anyone here have any ideas about this or has had this problem happen to them. Any help will be greatful thank you
