ENGINE CRANKS BUT WILL NOT START - continued

TM 10-3930-673-34

WARNING

Compressed air used for cleaning purposes will not exceed 30 psi. Use only with effective chip guarding and personal protective

equipment (goggles/shield, gloves, and so forth).

To bleed fuel system, engine must be placed in a run condition. Because engine may start during bleeding procedure, all

necessary safety precautions must be followed. See TM 10-3930-673-10 for additional information.

Keep clear of test spray from injection nozzle. Fluid at test pressures can penetrate skin, causing infection and possible death.

Drycleaning solvent (P-D-680) is TOXIC and flammable. Wear protective goggles and gloves. Use only in a well-ventilated area.

Avoid contact with skin, eyes, and clothes. Do not breathe vapors. Keep away from heat or flame. Never smoke when using

solvent. Failure to do so may result in death to personnel.

CAUTION

If rust has formed on injector hold-down nut, injector can turn in its bore as hold-down nut is loosened. Dissolve and loosen rust by

applying rust penetrating solvent to hold-down nut. Failure to do so can result in severe damage to cylinder head.

STE/ICE PRESSURE TEST

(1) Disconnect fuel hose from fuel transfer

pump.

(2) Connect STE/ICE pressure gage to

fuel transfer pump.

(3) Perform STE/ICE Test #24 and read

results.

(a) If fuel delivery pressure is at 10 psi,

go to Step 2 of this fault.

(b) If fuel delivery pressure is less than

10 psi, replace fuel transfer pump

(TM 10-3930-673-20).
