Malfunction
Test or Inspection
Corrective Action
If fuel linkage is defective, replace linkage.
Check injector timing.
If fuel injector and linkage is not defective and injector timing is within limits, proceed to Step 3.
STEP 3. Perform a cylinder compression check on all cylinders.
If compression is low in any or all cylinders, notify Direct Support Maintenance.
If compression is normal in all cylinders, proceed to Step 4.
STEP 4. Check for worn or defective valve guides or seals.
If valve guides or seals are worn or defective, notify
Direct Support Maintenance.
6. Lack of Power.
STEP 1. Check for loose connections on all fuel lines and for cracked or restricted fuel lines.
If fuel lines are cracked, broken or restricted, replace lines.
If fuel line connections are loose, tighten.
If fuel line connections are tight and fuel lines are not cracked or broken, proceed to Step 2.
STEP 2. Check for bad quality fuel. Remove fuel from fuel tank.
Install a new fuel filter element. Put a good grade of clean fuel in the fuel tank.
If fuel quality is good, proceed to Step 3.
STEP 3. Check for low fuel pressure. The outlet pressure of the fuel transfer pump must be at least 28 psi at full
load speed.
If fuel pressure is lower than the above pressure, install a new fuel filter element.
If fuel pressure is still low, check fuel transfer pump.
If fuel pressure is good, proceed to Step 4.
STEP 4. Check for leaks in air system. Check pressure in intake manifold. Look for restrictions in air cleaner.
If no leaks and restrictions are found, proceed to Step 5.
STEP 5. Check turbocharger for carbon deposits. Inspect and repair turbocharger as necessary. If no carbon is
detected, proceed to Step 6.
