Truck wont start. No fuel at test port fitting

I just change my fuel filter and then did the old 25 sec thing a couple of times. I started up the truck it ran for about 10 seconds then shut off. So I am thinking i need to reprime the fuel system. So i loosen the banjo bolt at the test port fitting and do the 25 sec pump thing a couple of times with no luck. So i try it about another 5 and still no fuel.

Does this mean i have a bad lift pump? I hit the water drain and i have diesel coming out.
I am a big time newbie to all this... and i just got the truck this past weekend. Now i have killed it. :(


It is a 2001.

Thanks for any help

Not necessarily. Do you have an adequate fuel supply? You might be sucking air from a broken line from the fuel tank side. Does the lift pump come on after you do the key bump thing?
If it comes on and no fuel comes out, try running the engine out of a five gallon bucket with diesel fuel. Prime your system like you did before. Start the truck. If the truck runs ok after five minutes or so, that means you have air in your fuel.

You might also want to check your fuel filter o-ring. Make sure that it didn't get damaged during installation.

The fuel tank is full, It was actually running decent before I changed the filter. I had been having some "sputtering" every so often but it ran fine. The lift pump does come on and i hear it running for the 25 seconds. Still no fuel at the test port. I did however have fuel pouring out when i did the water drain stuff.

I will be sure to check the o ring and make sure i didnt damage it during install. Thanks for the response and I will post how things go once i try some of this.

you may have not done it enough times to fill the filter and then get fuel out of the fitting here is the procdure.


STANDARD PROCEDURE - AIR BLEED
A certain amount of air becomes trapped in the fuel system when fuel system components on the supply and/or high-pressure side are serviced or replaced. Primary air bleeding is accomplished using the electric fuel transfer (lift) pump. If the vehicle has been allowed to run completely out of fuel, the fuel injectors must also be bled as the fuel injection pump is not self-bleeding (priming).

Servicing or replacing components on the fuel return side will not require air bleeding.

WARNING: DO NOT BLEED AIR FROM THE FUEL SYSTEM OF A HOT ENGINE.

Loosen, but do not remove, banjo bolt (test port fitting) holding low-pressure fuel supply line to side of fuel injection pump (Fuel Supply Line Banjo Bolt). Place a shop towel around banjo fitting to catch excess fuel.
The fuel transfer (lift) pump is self-priming: When the key is first turned on (without cranking engine), the pump operates for approximately 2 seconds and then shuts off. The pump will also operate for up to 25 seconds after the starter is quickly engaged, and then disengaged without allowing the engine to start. The pump shuts off immediately if the key is on and the engine stops running.

Turn key to CRANK position and quickly release key to ON position before engine starts. This will operate fuel transfer pump for approximately 25 seconds.
If fuel is not present at fuel supply line after 25 seconds, turn key OFF. Repeat previous step until fuel is exiting at fuel supply line.
Tighten banjo bolt at fuel supply line to 24 N·m (18 ft. lbs.) torque. Primary air bleeding is now completed.
Attempt to start engine. If engine will not start, proceed to following steps. If engine does start, it may run erratically and be very noisy for a few minutes. This is a normal condition.
Continue to next step if:
The vehicle fuel tank has been allowed to run empty
The fuel injection pump has been replaced
High-pressure fuel lines have been replaced
Vehicle has not been operated after an extended period
CAUTION: Do not engage the starter motor for more than 30 seconds at a time. Allow two minutes between cranking intervals.

Perform previous air bleeding procedure steps using fuel transfer pump. Be sure fuel is present at fuel supply line (Fuel Supply Line Banjo Bolt) before proceeding.
Crank the engine for 30 seconds at a time to allow air trapped in the injection pump to vent out the drain manifold.
WARNING: THE FUEL INJECTION PUMP SUPPLIES EXTREMELY HIGH FUEL PRESSURE 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: ENGINE MAY START WHILE CRANKING STARTER MOTOR.

Engine may start, may run erratically and be very noisy for a few minutes. This is a normal condition.

Thoroughly clean area around injector fittings where they join injector connector tubes.
Bleed air by loosening high-pressure fuel line fittings (Bleeding High-Pressure Fuel Lines at Injectors) at cylinders number 3, 4 and 5.
Continue bleeding injectors until engine runs smoothly. It may take a few minutes for engine to run smooth.
Tighten fuel line(s) at injector(s) to 38 N·m (28 ft. lbs.) torque.

you will have to do the second part if you started the truck and let the high pressure side run out of fuel

The procedures you posted are the ones i followed.
"If fuel is not present at fuel supply line after 25 seconds, turn key OFF. Repeat previous step until fuel is exiting at fuel supply line." I did the process at least 5-7 times and still no fuel at the supply line. Do i need to be more persistent with this part? any idea on the number of times I need to do this on average?
Also I assume i dont even start the high pressure side until i get fuel at the supply line?

Thanks for all the info it is greatly appreciated.

my guess is if you did it that many times and did not get fuel out but you are getting some in the filter is that your lift pump is going out to test to see if the lines are restricted open the bango bolt and put air pressure into the tank by tanking a rag to seal the fill neck to ensure it builds pressure to push fuel into the lines. It may take as long as 30 sec to a min to fill. If this gets fuel there you need a lift pump.

You are correct. Make sure your low pressure side is working fine before you get going on the high pressure side. Is your lift pump pushing the right amount of fuel volume and pressure now? Do you still have the no fuel out of lift pump problem? If so, try doing what I told you to do with the five gallon bucket. I know it sounds like a lot of work but if you do it, you know that you have a problem on the fuel delivery system.

Thanks to you all for your help. I took the filter out and checked the o-ring. Everything appeared okay. So i put the thing back together and then do the prime thing. I finally get fuel at the test port. So, I then have to prime at the injectors.... it took about (3) 25 Second grinds on the starter and then it sputtered and tried to start. I close the fuel lines and attempt to start and it does. I then proceed to do a little dance in the driveway... things appear to be okay. Took it out for a 30 minute drive and no codes..... will keep monitoring for the next couple of weeks.. and will be buying a fuel pressure gauge tommorrow to install.

Thanks again

Tim
