Timing issue 96 F150 4.6l Triton
Trying to help a buddy out on his truck and the timing is way off. He recently had to replace the motor and it was running rough and now wont run at all. Its my understanding that you cant time these motors like the older ones and the timing is controlled by the computer. I'm not having luck identifying which computer controls the timing and where it is located. Id appreciate any help. Thanks!

Thanks for the reply Adrianspeeder. The motor says triton right on it and the truck is 3/96.
When you crank the motor it stumble and stammers and backfire through the throttlebody and dies. Good fuel pressure, good injectors, new coil packs. To hear it, it absolutely sounds like a timing issue.

I don't think it's the hard timing. I think it is the PCM that controls the spark and fuel timing. I have spark and fuel just don't think it's doing it in the right time. I have spark so crank sensor is working. Checked cam sensor and seems to be working. But the computer takes the signal from the crank and the cam and figures what it should be doing but if it's messed up it will give incorrect orders of when to inject and how much.
