Ok so I was changing the bad lifter in the car today that was causing the knock i marked the cam and put it back on with the right mark on cam gear and chain. Put everything back on and started the car up and it ran fine for a few seconds i reved it up real quick to see if it was gonna knock and it didnt then the whole motor just stalled out and will not start! i love these motors but this used motor is starting to really piss me off!!! I checked the connections and everything seems fine but i will double check again here in a few after i calm down. i am getting 8 different codes. P0171, P0174, P0354, P0720, P0722, P1000, P2195, P0297. The 171 and 174 is running lean. the 354 which is my #4 cylinder cop, the 720 and 722 is transmission but think i know that issue. The 1000 is the computer not done loading, and 2195 and 2197 is a lot of options but the 2195 and 2197 has always been on the car even with my old motor. so prolly the 02 sensors... But why will the car not start???? turns over fine but will not fire up after it stalled...
