Archived Changed fuel filter, now truck wont start

[Black Cloud]

I replaced the fuel filter on my 2000 this morning, primed via bumping the key, and it ran for a about 5 seconds and quit. I tried to start it back up but would not fire. I do not usually fill the canister with fuel but did so thinking this may help but to no luck. The truck is sitting down at a friends so he can takre a look at it. Any clue what could have happened?

Did the O-ring(s) go back in thier proper location? If so, try cycling the lift pump by turning the key on for several seconds without hitting the starter, do this 5 or 6 times and see what happens!

thanks for the reply and yes the o-ring is seated properly againstb the lid. I tried to cycle the pump on numerous occassions but nothing. You could hear it humming. It started and ran fine before i tied the filter change. I am clueless.

Ok, a friend that went to a tech school taught me a trick. This is not supposed to be hard on anything. And I have done it myself, works awesome.



Take a clean rag, put some GASOLINE on it. Take the air intake boot off the air filter box, spread the rag over the intake boot and hold it tight while a friend cranks the starter. Takes a few seconds but it should start right up and pump the diesel right into the motor. Take the rag away and let it run for a few seconds. If it dies, repeat. After it runs for a few seconds, shut it down, verify that it starts and replace the boot on the airbox.

If you decide to use anykind of fluids to help start your truck, be sure to unhook the preheater grid connectors. You don't want the heaters to fire up and ignite the gasoline or whatever in the intake.



If you feel the need to try something like this, use WD40, after disconnecting the heater grids, have a bud spray WD40 into the intake hose while you crank on the starter.



We've all likely used gasoline to help start reluctant engines, we've all been lucky something bad didn't happen. I don't do it anymore.



Good luck, RJR

Sounds like a dead lift pump. You know you can force fuel flow by pressurizing the fuel tank, right? Just take a compressed air hose, a tennis ball, cut a hole in the tennis ball so you can push the air hose through it, place the tennis ball in the fuel filler neck with the air hose down the tube and put some slight pressure on the tank. (Don't get carried away with the pressure unless you like beach ball-shaped fuel tanks. )



You may have to do some cranking at full throttle to purge the air out of the HP lines, but it oughta start, even if the lift pump is dead.

Mine always starts hard after a fuel filter change. I have to crank it a long time and use some pedal to get it to go. A long time may be only about 15 seconds - but it feels like an eternity when you're used to it popping off almost immediately under normal conditions. Like yours, mine will fire right away and then die on the initial try. Then the cranking it longer procedure starts. My lift pump is fine, by the way. It sounds like you've done filter changes before, so maybe you've tried this already. Good luck.

Yep, it's certainly possible to get some air in the lines even with a good lift pump if the filter housing isn't completely filled and the line to the VP-44 purged well through the return line before cranking the engine.

Just got word that the lift pump is shot. I guess I had low pressure to start with and trying to start it repeatly did not help it. I had the injection pump changed under warranty about 8000 miles ago. Thanks for the help guys.

I found that when replacing fuel filter or trying to purge air from the system I need to fill tank completely full to get prime. Mel

For the 2000 engine and when the lift pump is working (did it fill the filter canister??) - get a wrench - break loose the 1, 3, 5 injector line nuts at the injectors and turn over the engine until fuel starts spurting out the line - kill the engine if it happens to start during this process. Re-tighten the lines!

Just read this post after coming in from the driveway having had the same problem, engine ran a few seconds after a fuel fulter change, then quit and would not start. I discovered I cannot read instructions: They say to purge the air from the fuel lines and filter after putting in a new filter. Do that by loosening the banjo fitting just below the HP pump, cover the loose fitting with a rag, then turn the key to START, but not long enough to fire the engine. This will cause the LP pump to run for 25 seconds, not just the 2 seconds when you only turn the key to ON. After doing the air purge correctly the engine started on the second try and ran fine.



Before I re-read the instructions, I called by buddy who I knew also had the same problem to find out how he solved the problem, but he was not home from work yet. He called back just after I had already solved my problem, with the same solution - read the manual, carefully!! So, apparently, many of us have this problem.

Nope the canister was bone dry. I have changed the fuel filter since day one myself and that was the first time it ever failed to prime.

Anybody have any leads where to get a lift pump. The dealer gave me a tag of $270.

Your local Cummins dealer - around half of that price.
