Direct And General Support Troubleshooting Procedures - CONT.MalfunctionTest or inspectionCorrective actionENGINE (CONT)4.ENGINE STARTS BUT WILL NOT KEEP RUNNING.Remove and test injectors (para 5-30).If injectors do not open at 3160 to 3307 psi (21788 - 22802 kPa), replace injectors.If injectors open at 3160 to 3307 psi (21788 - 22802 kPa), replace fuel injection pump (para 5-31).5.ENGINE SURGES (SPEED CHANGES).Remove and test injectors (para 5-30).If injectors do not open at 3160 to 3307 psi (21788 - 22802 kPa), replace injectors.If injectors open at 3160 to 3307 psi (21788 - 22802 kPa), replace fuel injection pump (para 5-31).6.ENGINE IDLES ROUGH.Step 1. Inspect engine mounts.If engine mounts are loose or damaged, tighten or replace engine mounts (para 5-31).If engine mounts are not loose or damaged, go to step 2.Step 2. Remove and test injectors (para 5-30).If injectors do not open at 3160 to 3307 psi (21788 - 22802 kPa), replace injectors.If injectors open at 3160 to 3307 psi (21788 - 22802 kPa), go to step 3.Step 3. Check engine compression on each cylinder.If compression for each cylinder is not 350 psi (2413 kPa), replace piston rings or pistons(para 5-67) or cylinder sleeves (para 5-63).If compression for each cylinder is 350 psi (2413 kPa), replace fuel injection pump (para 5-31).5-10
