I just finished Replacing my 4.7 engine which had a spun bearing with a re manufactured engine. Before I did the swap I looked at the crank ring and it has 16 teeth like my original engine. I looked at the timing and when the crank was at the indicated TDC on the exhaust stroke the cams where both lined yo with "V8" at 12 O'clock.

I installed the new long block engine using all the original sensors except for the crank position sensor. I broke the original crank position sensor trying to remove it from the original block. I purchased a new from the dealership.
Once the install was completed I double checked everything and tried to start it. Every time I crank it, it sputters a bit. Almost like it is trying to start on one or two cylinders. I pulled the plugs and could smell fuel on them. 6 of the 8 still looked brand new while two had a little black on them. I determined that it was trying to start on only two cylinders. I placed the spark plug from one of the ones that was still clean against the engine to watch to see if it sparked. My wife cranked the engine and I saw it spark on the first engine rotation but it never sparked again after that.

I check the fuel rail for fuel by pressing on the fuel relief port. Fuel did come out. I connected my code reader and I don't get a code while cranking.

I'm know there is fuel pressure at the fuel rail. Compression is good. I check it at they were all around 120psi. I'm pretty sure spark is controlled by using the cam position as feedback. So I'm kind of leaning towards purchasing a new cam position sensor.

Does anyone have any suggestions?

 

Are you sure the OHC were lined up with the crank on the new motor?

Also did you make sure you turned the engine to the same marks before removal?

Did you reset the PCM?
