my buddie just got an 01 and it has the code p0093 in it and it has a real heavy fuel smell and the oil looks like it might have some in it but cant really smell it. the balance rates look good and I commanded 160mpa and it gave me 19 to 20 k on the cp3 and was wanting 23k. what else could I be looking for?

If you're down a few thousand psi when you command max rail it's usually injector(s). Remember balance rates are only a relative comparison of injectors to each other. All 8 injectors can be worn out, leaking externally or returning to much fuel and still have good balance rates. If he doesn't want to bite the bullet and buy all 8 right away better find a bosch shop to test them.

X2 balance rates don't tell the whole story. You can do a return test on the injectors. The heavy fuel smell and fuel in the oil sounds like injectors though.
Sounds like a bad CP3 unfortunately. I'd check fuel filter and housing first seeing as its the cheapest thing to rule out. Then you're basically left with the injectors, return lines, and CP3.
