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).
