2001 F350 7.3L Diesel won't start

I've been troubleshooting this for 3 days now and am to the point I know I need to bleed the fuei line, but I can't find a valve anywhere. I know pressure is good at 100 psi on the incoming line to the filter. Haven't tested on the outgoing. No smoke from the exhaust at any time.

    2001 PCED OBDII-Diesel SECTION 3: Symptom Charts AO: Symptom Chart 14 AO: Introduction AO1 CHECK OIL RESERVOIR Confirm SAE viscosity and API rating of oil. Remove oil reservoir fill plug and refill reservoir. Start engine and test drive vehicle for 16 kilometers (10 miles). Remove oil reservoir fill plug and check reservoir oil level. Is oil reservoir full? Yes No GO to AO2 . GO to AO3 . AO2 RECHECK OIL RESERVOIR Note: Perform the following step before starting engine. Check oil level in reservoir. Allow vehicle to sit overnight. Remove oil reservoir fill plug and check reservoir oil level. Did oil level change? Yes No GO to AO3 . GO to Pinpoint Test AC . . AO3 CHECK FOR OIL LEAKS Inspect engine valley, front cover and reservoir for signs of oil leakage. Remove high-pressure oil pump. Inspect for internal leak pass across high-pressure oil pump gasket beads. Remove oil reservoir cover. Inspect oil reservoir for casting porosity. Is there an oil leak? Yes No REPAIR as required. REFER to the Workshop Manual. VERIFY symptom no longer exists. GO to AO4 . AO4 CHECK OIL PRESSURE AT RESERVOIR Remove fill plug or oil pressure unit. Install gauge and measure oil pressure at idle, engine warm. Is oil pressure 83 kPa (12 psi) or more? Yes No GO to AO5 . INSTALL a new oil pump. REFER to the Workshop Manual. VERIFY symptom no longer exists. AO5 CHECK ENGINE OIL PRESSURE Note: Low oil pressure from the engine oil pump can also cause low oil levels in the reservoir. Measure engine lube oil pressure. Plug located on left side of block just above the oil pan rail can be used as a test port. Is oil pressure 55 kPa (8 psi) greater than pressure at reservoir? Yes No REPAIR the cause of pressure drop between main oil gallery and reservoir (rear plug for tappet gallery or tappet out of bore). REPAIR the cause of low lube oil pressure (pump regulator valve). REFER to the Workshop Manual.

    Injector Driver Module The solenoid-operated poppet valve requires 115 volts at up to 8 amps to operate, which is more power than the PCM can supply. Therefore, a high power device, the Injector Driver Module, is used to supply power to the solenoid on command from the PCM. PCM Control of Fuel Injection The command signal from the PCM to the Injection Driver Module is the Fuel Delivery Control Signal. The poppet valve requires 12 volts to command the poppet open and 0 volts to command the poppet closed. The PCM also supplies a synchronizing signal, CMP, to indicate cylinder No. 1 (going from 0 to 12 volts) and cylinder No. 4 (fires 5th) (going from 12 to 0 volts). Engine Timing The PCM controls both duration and timing of the injection event with the fuel delivery control signal. Signal duration, or fuel pulse width, is shown as Parameter ID (PID) "FUEL_PW" on the scan tool. The PCM controls the fuel plunger injection pressure and fuel volume by varying the injection oil pressure with the Injection Pressure Regulator. The command to the Injection Pressure Regulator is a 12 volt, Pulse Width Modulated (PWM) signal (controlled on the ground side). The injection oil pressure command is shown as NGS PID IPR which is the percentage ON of the pulse width modulated signal. Injection oil pressure is shown as NGS PID ICP. The PCM receives engine rotational position information from the Camshaft Position sensor (CMP). The CMP is a hall-effect device. It outputs 12 volts to the PCM whenever it detects the iron of a spoked target wheel in front of it, and it outputs 0 volts whenever it detects the space between the spokes. The target wheel spokes and spaces are each 15 crank degrees, except for narrow spoke which indicates cylinder No. 1 and a wide spoke which indicates cylinder No. 4 (fires 5th). The NGS PID RPM is generated by the PCM from the CMP signal. Fueling Corrections The PCM adjusts injector output based on oil temperature information received from the Engine Oil Temperature sensor and turbo boost information received from the Manifold Absolute Pressure (MAP) Sensor, and the Barometric pressure (BARO) sensor. These corrections are necessary to meet emissions requirements and to optimize power. The Engine Coolant Sensor is used as the primary input to the Electronic Control System to enable adaptive cooling. This provides a means of providing adequate cooling in severe engine temperature conditions. When ECT is greater than 107°C (225°F), the fueling rate of the engine is modified to provide cooling protection and prevent engine damage due to overheating. Outputs of these sensors are displayed on the NGS tester as EOT (temperature), MAP (boost pressure), BARO (pressure), and BARO V (volts). MGP shows boost.

I take it you have a crank no start issue, the fuel is injected by high pressure oil, no oil pressure no start, there are 2 oil pumps, low lube pressure and high injection control pressure (ICP) the injection system is hydraulic controls electric actuated fuel injection, if when you crank the engine over and the oil pressure guage goes up base pressure is ok, then its high pressure or the best thing I can say is pull codes and that can give me a good direction to send you in, there are many things that can cause that problem, if the fuel heater shorts out, the pcm and it are on the same 30amp circuit causin the same problem and still you would have proper fuel pressure readings.

How do you bleed a diesel pump jeep Cherokee turbo diesel 3.1 5 cylinder 2001


we dont have this engine here, USA.
but i have the WG jeep book,
starting page 12 , chapter 14


FUEL INJECTION PUMP BLEEDING
(1) If the fuel injection pump has been replaced,
air should be bled at the overflow valve before
attempting to start engine.
(a) Loosen the overflow valve (Fig. 18) at the
rear of the injection pump.
(b) Place a towel below the valve.
WARNING: WHEN CRANKING THE ENGINE TO
BLEED AIR FROM THE INJECTION PUMP, THE
ENGINE MAY START. PLACE THE TRANSMISSION
IN NEUTRAL OR PARK AND SET PARKING BRAKE
BEFORE ENGAGING THE STARTER MOTOR.
CAUTION: Do not engage the starter motor for
more than 30 seconds at a time. Allow 2 minutes
between cranking intervals.
(2) Crank the engine for 30 seconds at a time to
allow air trapped in the injection pump to vent out
the fuel injector drain tubes. Continue this procedure
until the engine starts. Observe the previous WARNING
and CAUTION.
(3) Tighten overflow valve.
HIGH-PRESSURE FUEL LINE BLEEDING
WARNING: THE INJECTION PUMP SUPPLIES HIGH-
-PRESSURE FUEL OF APPROXIMATELY 45,000 KPA
(6,526 PSI) TO EACH INDIVIDUAL INJECTOR
THROUGH THE HIGH-PRESSURE LINES. FUEL
UNDER THIS AMOUNT OF PRESSURE CAN PENETRATE
THE SKIN AND CAUSE PERSONAL INJURY.
WEAR SAFETY GOGGLES AND ADEQUATE PROTECTIVE
CLOTHING AND AVOID CONTACT WITH
FUEL SPRAY WHEN BLEEDING HIGH-PRESSURE
FUEL LINES.
WARNING: DO NOT BLEED AIR FROM THE FUEL
SYSTEM OF A HOT ENGINE. DO NOT ALLOW FUEL
TO SPRAY ONTO THE EXHAUST MANIFOLD WHEN
BLEEDING AIR FROM THE FUEL SYSTEM.
Bleed air from one injector at time.
(1) Loosen the high-pressure fuel line fitting at
the injector (Fig. 19).
(2) Crank the engine until all air has been bled
from the line. Do not operate the starter motor
for longer than 30 seconds. Wait 2 minutes
between cranking intervals.
(3) Start the engine and bleed one injector at a
time until the engine runs smoothly.

Hi , I have just replaced the fuel fiter on my VW Tansporter T4 TDI 2.5 diesel 2001. How do I bleed it? I can not see the fuel through the hoses as they are black..


Close the filter drain cock, remove the filter, fill the filter with fuel and put it back on. Now crank the engine to start at a faster speed and let it blubber till it smooths out and your good. If you\'ve been cranking on it already, hope not, then you have allowed air into your fuel system and you must bleed all the air out at the injector lines until there is fuel coming out of each line you\'ve got cracked open at each injector. It will take some time and a lot of cranking. But if you do it like I said to start with, it will start easily. I\'m an old timer and love diesel engines. Old school way is the only way.

How do you bleed the diesel fuel filter on a 1986 Toyota diesel Land Crusier?


I don't know a lot about these trucks but I can tell you that somewhere between the spin-on fuel filter and the I.P. (injection pump) is a 1.5" dia X 4" long steel primer. Just under the top of it is a spring. You will need to loosen or open the "Fuel supply line", at the I.P. (going from the filter, to the pump) and manually pump the fuel primer. Continue pumping the fuel primer until diesel flow from the opening. Quickly close off the drain-port or fuel-line, pump the primer a few more times (to increase line pressure and try to start your vehicle. After it starts, check for leaks. Let me know if I can help anymore. Good luck.

First thing to try with any diesel that won't start is to do a diesel system bleed. This one should be before the HP fuel rail type so start by bleeding the lift pump, then the fuel filters, then the main injector pump to lines to the injectors and lastly the injectors. Good luck.

My 5.9 dodge cummins diesel won't start, I've replaced the fuel lift pump, and the fuel filter, turns over. But will not start?


Most likely you just have air in the lines.Crack them open one at a time and bleed them with the fuel pump off and on till you get fuel.If it fires dont hit the throttle let it sit and idle and close the line.Does it fire up with a small whif of starting fluid?

2001 Rodeo 2.8 Turbo Diesel running perfectly one day won't run the next. Seems to be after it sits for a couple of days. Any suggestions?


Hi Peter, If the vehicle turns on the starter all the time, and sometimes starts and other times fails, check the fuel filter for leakage. Sometimes air gets into the fuel system. When it gives problems, open the bonnet (hood) and have someone pump the pump on top of the filter housing. If it feels soft when beginning to pump, I would suspect either a leakage on the fuel line or the filter housing. If you need to replace the housing and filter, remember to fill the replacement filter with clean diesel fuel first. the glow plugs can also cause problems if one or more have burned out. Regards John

Ran out of diesel now vehicle won't start


This is not unusual on a diesel. What happens is there is air in the system. If this vehicle has an electric fuel pump loosen line where fuel enters injection pump then turn ignition key to the on position and watch for fuel to appear and then quickly tighten line before turning off key. Then try to start. If does not have electric fuel pump will need a second person. One will loosen line and watch while other cranks vehicle until you get fuel and tighten line before the other person releases ignition switch unless vehicle starts first. If that doesn't do the job do this where line hooks onto each injector. Probably will not have to do this to all injectors but could run rough until all the air gets out of everything. I have farmed with diesel tractor for 25 years and dad I drove the gm vehicles with the 5.7. You normally don't start a diesel without bleeding the air out of the lines although some will self bleed most won't. Hope this does the trick.
