Replaced the 4.7 iter Engine,
Replaced the PCM,

Vehicle is rolling but not starting.

Any ideas what could be the problem?

If you need a video, I can gladly email it to you.

Please send any suggetions as our mechanics are clueless and we need to get the customers vehicle out of the shop ASAP.

Thanks,

 

Need alittle more info here. Year? Turning over and not cranking or not turning over? Fuel pressure? DTCs? does the vehicle have a grey key or black key?

 

Year-2002
4.7lt

any help would be great..

 

any one got any thing???

 

P0340 is for the cam sensor. I guess the simplest thing to do would just be to make sure its plugged in. The PCM will run rationality tests every time you go to key on, and if the sensor is unplugged it will set the code before you try and crank it. I know that little things like that can be easy to overlook when you do a more involved job like that. Also, was it a reman engine or a junkyard R&R job? If you removed the old cam sensor and installed it in the replacement engine, the air gap may be wrong because those things usually come new with a paper disc on the end of the sensor.
