Next to the tank at the top of the body under neath. or on the updated version engine bay follow the fuel line and it goes into a contaner with 2 pipes on it that is the filter.

check the mass airflow sensor circuit; thats what the owners manual says DTC code 12 pertains to, but to me it sounds like a fuel pump. i had the same problem, it would turn over, but not crank. make sure youre getting spark and everything else first because the fuel pump is located in the gas tank, and requires removing the entire tank to access it, which easily can turn into a 4-6 hour job.

Chances are the coolant temperature sensor or its wiring have failed, or the vacuum line to the MAP sensor is leaky or broken (I believe the V12 in '89 guise uses MAP sensors). The MAP sensor measures Manifold Absolute Pressure. Along with this pressure the ECU looks at engine RPM. It also measures air temperature. Knowing pressure and temperature we know density, and knowing engine speed tells us how much volume of air is going through the engine. All of this together is computed into air mass and is used to calculate how much fuel mass should be admitted. If the vacuum line is broken, the ECU reads less vacuum and produces rich mixture thinking that the engine is under high load.
SOURCE: No oil pressure what so ever in v12 jaguar
have you tried reversing the pipes and see if that makes any difference other than that there must be a pressure difference between the two pumps try priming the filter with oil before starting.

There are two 13mm bolts in the back window under the carpet that have to be removed. Remove the two plastic screws, Remove the carpet and find the two 13mm bolts..
