The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Record by record

20 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

Work done

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

  1. Manufacturer communication2001–2002 GMC THE 4.8L RPO LR4 (VIN V), 5.3L RPO LM7 (VIN T), AND 6.0L RPO LQ4 (VIN U) (YUKON) ・ 2002-01-01

    Changes to the Gen III engines' fuel injection system for 2002, and the parts specific to the E85-capable L59

    1. 1Fault

      • The 5.3L L59 has an E85 compatible fuel system, which can handle fuel that is up to 85% ethanol. Its fuel system components are specially designed to survive in this environment. Because of this, fuel rail service is different from the other Gen III engines.
      • For 2002, there will be early and late model intake air fuel modules (IAFM), consisting of the throttle body, fuel rail and injectors, and intake manifold. The early IAFMs will be the same as 2001.
      • The PCV valve will be changed from a variable valve to a fixed orifice.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      • The fuel pressure is different for this application (the E85 fuel rail): 334 to 375 kPa (48 to 54 psi).

    3. 3Correction

      Repair

      • The late production IAFMs on engines that do not require EGR will have a cast-over EGR port. All service replacement manifolds for 2002 will have an open EGR port. If the manifold you are replacing does not have EGR, you must install the supplied plug and screw, following the instructions in the parts package.

      Parts

      • The L59 uses Denso injectors, which are not interchangeable with the Multec 2 injectors used in the other Gen III applications.
      • Because of this, the right fuel rail, left fuel rail and fuel crossover pipe are available only as a complete assembly.
      • The fuel pressure regulator is also specific to the E85 fuel rail. It is larger in diameter than those used in the other Gen III engine applications and uses a special diaphragm that is compatible with E85 fuels.

      Caution

      • If you replace the O-rings, be sure they are specific to this injector. The Denso injector is longer than the Multec 2.
      • The L59 fuel rail is made of a special material that is resistant to degradation from E85 fuel. Special thread-cutting screws hold the fuel crossover in place. Do not remove these screws. Re-installing them will cut new threads, destroying the former threads and creating a possibility of failure.
      • Three different fuel pressure regulators are used this year. Each one is held in place on the fuel rail by a unique retainer, and the retainer diameter and window dimensions are different for each. Use the correct retainer to ensure adequate retention of the fuel pressure regulator.

    Changes to the Gen III Engine Family Fuel Injection System In 2001 the Gen III engine family was comprised of the 4.8L RPO LR4 (VIN V), 5.3L RPO LM7 (VIN T), and 6.0L RPO LQ4 (VIN U).

    Starter keeps cranking after the key is released: a normal condition, the PCM controls the starter relay (reminder of bulletin 03-06-03-001)

    1. 1Fault

      • Owners may comment that the engine starter continues to run after the key is released (ghost crank).

    2. 2Finding the cause

      Possible causes

      • On these vehicles, the starter relay is controlled by the PCM, with input from the key switch.
      • After 0.4 seconds of cranking, a timer is activated in the PCM. Once this happens, even though the key is released, the PCM will continue to crank the starter until the engine starts or a no-start time limit is reached.
      • The fuel pump module may take several seconds to build fuel pressure, particularly after sitting overnight.
      • The automatic crank feature ensures sufficient crank time even if the customer releases the ignition switch prematurely.

    Starter Cranks After Key is Released -- Reminder Owners of 2003 C/K trucks with the 5.3L Engine (VIN Z -- RPO L59), and 2004 C/K trucks with any engine, may comment that the engine starter continues to run after the key is released (ghost crank). Owners of 2003 C/K trucks with the 5.3L Engine (VIN Z -- RPO L59), and 2004 C/K trucks with any engine, may comment that the engine starter continues to run after the key is released (ghost crank). This is a normal condition and no repairs should be attempted for this condition. On these vehicles, the starter relay is controlled by the PCM, with input from the key switch. After 0.4 seconds of cranking, a timer is activated in the PCM. Once this happens, even though the key is released, the PCM will continue to crank the starter until the engine starts or a no-start time limit is reached. The fuel pump module may take several seconds to build fuel pressure, particularly after sitting overnight. The automatic crank feature ensures sufficient crank time even if the customer releases the ignition switch prematurely.
