The fuel injectors will make a tapping sound. If you use a mechanic's stethoscope and put it to each one, you'll hear it loud and clear. It will sound like someone's hitting an anvil with a hammer. If you're not sure that's the sound, you can use the stethoscope to probe around.

OR as I did as a teenager, use a cut off broom handle. One end on the part you're listening to, the other in your ear! Believe me, it works.

Same thing works if you use a long screwdriver up to your ear........... uh just in case it has to be said out loud........ put the plastic end up to the ear, not the other end. This way you get to keep your broom.

Gas quality may be an effect

In my 2000 3.0L V6, I have noticed the "clicking" under load. According to the forums, this is a common noise associated with the 3.0 Vulcan motor. I contend that by changing where I have fueled up, what type of octane rating, and also the usage of injector cleaners and/or additives is directly correlated to the frequency of you the driver noticing the clicking that I've described above.

Here's what I've noticed so far in 91,000 miles:

1. 87 octane makes the noise, no matter what gas brand I purchase. Some brands cause my truck to create more noise than others.

2. The use of 89 octane significantly lowers the clicking/pinging/knocking noise.

3. The use of the fuel system cleaner named "BG 44K" eliminates the noise for about 5 tanks of 87 octane. It (the noise) eventually creeps back into the fray.

4. The correct proportional use of Marvel Mystery Oil in the fuel, no matter what octane or brand, eliminates most if not all of the noise when in use.

Hope this empirical evidence works... but remember, every FORD is different.

Experimentation, like what I've done above, is the key. Kinda like "bonding", ya get to know your truck better!
