Hey man awesome video ! First of all did this remedy your issue ? Also were you getting fuel to the filter housing with the lift pump being bad ? I have an e350 "CRANK NO START" and I've bled the system and did return lines and much more but still not firing.
Here I am laying under this damned thing scratching my head as to how tf ima do this with the alternator still on. Thanks for the video though super helpful shoulda watched before getting started lol
No need to bleed. It bleeds itself. The lift pump moves way more fuel than the truck burns, so it ultimately pumps back to the tank. Not to beat a dead horse, but I highly recommend going with an electric pump.
Mine flickers according to the rpm. There is a short to ground or open somewhere causing the erratic indication. Your fuel liter is not clogged. Just drive it
My trunk is the same motor and I have to pump the gas pedal like crazy to get it to start after it starts it doesn't want to keep running, And when I give it gas it is very slow in responding to the gas pedal I give it gas and a couple of seconds later the motor response, Do you think it is the same problem you had with this trunk? Thank you for your time
Year make model what engine? 6.9/7.3 idi. Two connections at the top of the pump on closes to the radiator is fuel shut off make sure its energized to start. Run a hot wire from positive terminal to it. Hold the sherade vavle at the fuel filter housing. With Ignition on bump the starter solenoid over see if air is in it. Crack Open the injector lines see if there getting fuel. The return line cups and lines see if they leak check filter and all fuel lines for air intrusions. If main injection lines are cracked open and you put diesel fuel in the fuel filter and turn the engine over it should at least pressurize the diesel and see bubbles and fuel at top of injectors. Can also pull fuel line to see if manual lift pump is priming fuel. An electric pump can be used some folks like them. But the manual pump last long time and mine lasted almost 40 years!! My other truck(7.3idi) as soon as electric pump got some age it would stop once it got hot! Put another 70.00 electric pump it worked a year went back to manual never any issues since!!
@@user-km3sg1hy9s it's a 1994 7.3 Cummings motor! I am pretty sure it needs a fuel pump, I was thinking of putting mechanical fuel pump, using a 12V DC pump: Just like this guy did the second time I think that will be the best thing to do! I am just waiting for it to get a little warmer outside! I have a lot of work now with my Tractor I am replacing the hydraulic hoses and rebuilding the Hydraulic cylinders on all four cylinders fun right LOL Not too bad so far!
Pretty sure the arm goes under the cam. It's been a while, but I do remember just looking at the old one to see which side was worn. I need to post another video. After replacing the mechanical pump, it would finally get going, but it was still a bitch to start. I ended up putting in an electric pump an wiring it to the ignition switch. She now starts up as quick as my car.
Not really. My truck has over 200k miles on it and I think the cam lobe that drives the mechanical pump is actually worn down. I recommend using a 12V electric pump. I have another video on that.
Don't bother replacing the mechanical pump, use an electric pump instead. See link in video description.
Mechanical pumps are better
If electric system fails your stranded
Like Alternator failure emp attack ect
Mechanical pumps are more reliable. electric pumps are just better at priming the fuel system.
I've had my truck new since 1986 almost 40 years had both electric and manual. There's a good reason to have manual pump.
Lord someone with a great explanation, sir thank you
I just did mine all through the wheel well in a parking lot. It was a pain in the ass I was about to blow it up

Try doing this job on an Econoline Van with the 7.3, it's all from the bottom cuz no matter what you remove from the top just simply no room.
I have heard the vans are a real pain in the ass to work on

Man, forget about that lift pump. Put in an electric pump. Works waaaaay better.
@@stevel6220 did it run after you put the pump on?
well? did that fix it?
Do you have to bleed the fuel system after you install the new one?
No need to bleed. It bleeds itself. The lift pump moves way more fuel than the truck burns, so it ultimately pumps back to the tank.
Not to beat a dead horse, but I highly recommend going with an electric pump.
Hello I have a 93 f350 and I'm having problems with fuil filter message and I changed so many times already. Any advice thanks in advance.

Replace fuel filter also check timing

@@The1313jeff do you have a channel??
A long time ago!@@user-km3sg1hy9s
the arm has to be under or on top of the cam?
Pretty sure the arm goes under the cam. It's been a while, but I do remember just looking at the old one to see which side was worn.

Did the pump fix it
A DC electric pump is the way to go

I looked this up because I was able to get the old pump out, but can’t get the bolts lined up to get the new one in. Guess I’m pulling the alternator.
You have to put something back on on so the crankcase isn't open to the elements, but I highly recommend just using an electric pump
@@stevel6220 next time.
You should’ve deleted it, & went with an electric pump.
I did go with an electric pump...see the description
