Check for faulty fuel injection pump. Run engine per TM 5-3895-373-10. Look for excessive
smoke and oil flowing from dipstick flange. Remove dipstick and inspect viscosity of engine oil.
If engine oil is thin or watery, if excessive exhaust smoke is observed, or if oil is seen flowing
from the dipstick flange, replace/repair faulty fuel injection pump per paragraph 2.19. After
replacing or repairing fuel injection pump, change engine oil per LO 5-3895-373-12.
WARNING
Fuel is very flammable and can explode easily. To avoid injury or death: Always wear safety
glasses/goggles at all times.
Keep fuel away from open flame or any spark (ignition source).
Keep at least a B-C fire extinguisher within easy reach when working with fuel or on a fuel
system.
Do not work on a fuel system when engine is hot; fuel can be ignited by a hot engine.
Post signs that read, "NO SMOKING WITHIN 50 FEET" when working with open fuel lines
or fuel tanks.
Direct contact with a high pressure fuel spray may cause serious injuries. Avoid direct
contact with fuel spray. If fuel spray penetrates your skin, get medical aid immediately. Eye
protection and rubber gloves should be worn when working with fuel.
Step 3.
Check function of fuel injectors.
If the engine will not start and fuel has been found at each injector per step 1, inspect and repair or
replace faulty fuel injectors per paragraph 2.18.
If no fuel is found at any injectors, replace/repair fuel injection pump per paragraph 2.19.
