TM 10-3930-671-24 Table 4-2.  DS/GS Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION ENGINE 1. ENGINE WILL NOT START. Step 1. Check for faulty fuel injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is faulty, replace injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is OK, go to step 2. Step 2. Check that fuel injection pump timing is property set (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injection pump timing is not set properly, set timing (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). If fuel injection pump timing is set properly, injection pump is faulty.  Replace injection pump (Appendix F, Continentel Diesel Engine, Section 4.14, Section 5). 2. ENGINE DOES NOT RUN EVENLY. Remove fuel injector from cylinder with lowest compression rating, squirt oil into cylinder, install fuel injector, and then check compression at that cylinder (Appendix F, Engine Compression Pressure Check, Section 4.6). If compression reading rises for that cylinder, faulty compression rings are indicated.  Overhaul engine (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). If compression reading does not rise for that cylinder, sticking or burnt valve Is indicated. Remove and repair cylinder head assembly (Appendix F, Continentel Diesel Engine, Section 4.14, Section 8). 3. A LOSS OF POWER. Step 1. Check for faulty fuel injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is faulty, replace injector(s) (Appendix F, Diesel Fuel Injection System, Section 5.3). If fuel injector(s) is OK, go to step 2. 4-2
