If the motor has common rail injection it doesn't have a conventional injection pump but it does have a high pressure pump and if the pressure is slow to build due to air leaks, drain back or wear then injection will not begin until the rail pressure is sufficient.
If there is a conventional injection pump it can still suffer similar maladies but will not be capable of generating such expressive codes.
Codes incidentally, often indicate a relay or sensor or something has a fault, though that isn't as simple as it sounds and a code read is only a small step in a diagnostic process. Often it is just as likely the circuit that has the fault - wiring, connections or the ECU itself. Sometimes a fault code is an indication of a fault elsewhere. Other test equipment should be used to verify the fault code and no component should be replaced until it is found to be faulty using independent testing methods and when something must be replaced the circuit should be tested and success verified before moving on to the next stage.
Basics first is the best practice rule and in addition to the obvious basic stuff it is worth noting a good cranking speed is essential and the injector spray patterns and pressures should be tested and while the injectors are out being tested/overhauled why not do a compression test...

If its not leaking on the ground, it must be leaking into the coolant via radiator. Nowhere else for it to go...
Fault code "no bus"
Vehicle
The "NO BUS" points to PCM communication failure. Disconnect the battery negative then unplug and plug back in the PCM connectors. Reconnect battery and run engine. Try pulling DTCs with a code scanner. If the PCM won't communicate, it's probably fried.
My belt fell off and
belts dont just "fall off" find out what is wrong. .http://www.gates.com/common/part_locator/view_diagram.cfm?id=S8023
Remove an alternator from a
as always begin with the negitive on the battery remove terminal.there is what they call a ideler pulley for serpentine belt it typically takes a 3/8 ratchet to put torque on it to remove tension on belt ounce youve completed the belt tension removal move on to the altenator always if in daught on wiring create hand written diagram of wiring.remove wires now take tensioner bolt out,there should be one more for pivoting remove as well.reinstall in reverse.

I don't understand what you mean about the engine gaining RPM. Does it run alright, and just overheat with a/c on? If so, I would suspect your fan clutch. Hope this helps, TJ

remove belt and check to make sure shaft is not broken inside of pump. if that checks good then most likely just weak pump.
A/c compresor quit blowing in

There is no relay. The pressure sensor sends signal to PCM, then the PCM sends signal to the TIPM or total integrated power module which is sort of self contained fuse box but really a micro computer that controls many things. The Module has had known issues that can affect one of many things. I lean to bad module. Here is the diagram for compressor.
The Integrated Power Module (IPM) is a combination of the Power Distribution Center (PDC) (1) and the Front Control Module (FCM) (2). The PDC mates directly with the FCM to form the IPM. The PDC is a printed circuit board based module that contains fuses and relays, while the FCM contains the electronics controlling the IPM and other functions. The IPM is located in the engine compartment, next to the battery and connects directly to the battery positive via a stud located on top of the unit. The ground connection is via electrical connectors. The IPM provides the primary means of voltage distribution and protection for the entire vehicle.
The molded plastic IPM housing includes a base and cover. The IPM cover is easily opened or removed for service access by unscrewing the cover retaining nut and has a fuse and relay layout map integral to the inside surface of the cover. This IPM housing base and cover are secured in place via bolts to the left front fender support assembly.
Replaceable components of the IPM assembly are broken down into the following components:
- The Power Distribution Center (PDC)
- The IPM cover
- The Front Control Module (FCM)
- Complete IPM assembly that includes all three parts
All of the current from the battery and the generator output enters the integrated power module via a stud on the top of the module. The integrated power module cover is removed to access the fuses or relays. Internal connections of all of the power distribution center circuits is accomplished by a combination of bus bars and a printed circuit board.
