I have a 2003 Dodge ram 1500 with a 4.7l magnum v8, my truck would crank over and start and then sometimes it would just crank over. I finally got a p0335 code and changed out the crankshaft position sensor and now it starts and runs. But when I would first start it it would be sputtering and when I would put it in drive and hit the gas it would take a second to get acceleration, but once I drive it and it warms up it gets better. Then my check engine light would come on and now it's a p0171 which is fuel running to lean. Has anybody had this issue that could help me to figure it out.

 

Fuel pump most likely,clog or injector

 

im having an issue with my 03 dodge ram 1500 4.7l having a no start situation. it always throws the same code of p0335 (CKP). i replace the sensor 3 different times. I have changed the CMP, i have check the wiring to the plug and the plug itself and also i checked the toner wheel for breaks all good. at this point im pretty stumped i was thinking it could be a glitch in the ecu or sometime????

 

It could possibly be a bad PCM.
