got 70 model ford 3000 three cyl diesal changed filters has fuel to 2,3 but none on 1 any help will will be greatly appericated
 
If you add a little air pressure to your tank only takes a few lbs. it will push the fuel thru the filters. Make sure the lines are open before you do this. I added a valve stem to an old cap for this procedure, works for me. Nearly full tank helps too.
 
Back off the nut on the injector line at the injector while it's running until fuel starts flying out and then tighten the nut again. This will force the air out of the line. Be very careful not to have you hands or face close to that nut. Fuel can be injected into your skin. You do not want that to happen.
 
If your simms is like the simms on a nuffield there are two bleeder on the side of the pump just below the distribution block, the injectors can be bleed at the fuel return from injectors to the filter if they are plumbed that way, other wise crack the injection line.
 
If it's like the '68 3500 I've got, and it's got the Simms pump, it has probably never had the oil in the pump changed. In fact, there may not be any oil left in the pump. This is because most folks don't even know the Simms pumps don't lube off the engine as there is nothing in the manual to let them know.

s far as your problem, it's probably a stuck plunger on #1. What happens is the cam pushes the plunger up, and it sticks. Without it riding up and down against the cam you get no fuel from that injector line.

Mine did it a few years back, but in my case it was all three plungers that stuck. This is when I found out that the pump had it's own lube oil system....and was dry as a bone.

If I remember right, you can pull that plate off the side, and see the plungers where they ride against the cam. If it's stuck, you might try spraying it with some penetrating oil and seeing if it will free up.

With all of mine stuck at the same time, I had to pull the top off the pump so I could get to everything. It didn't take but a little bit to do it. Once done I filled it with a little oil thinned with a touch of diesel fuel. I let it run this way for a few hours to clean the crud off the inside, and then drained it and put in straight oil. You might get away with putting a similar mix in yours and running it a little but to see if the stuck plunger will free up. If not you can do like I did and pull the top end off the pump and free it up without having to pull the whole pump off the engine.
 

When I utilize compressed air to help push fuel from tank to IP I use short bursts of air but have never checked/regulated the psi. I think it would require a lot more than 10 psi to damage a Ford 3000 metal fuel tank. IMHO Ford 3000 is one of the orneriest fuel systems to bleed. I could bleed my previously owned 3000 forever then get disgusted & attach a tow chain then in less than 10 ft of towing the engine would fire up.
 
I can't imagine why anyone would use air to push fuel in this system. It's got a lift pump which is fed by gravity from the tank along with a hand primer on the lift pump............

As Wayne stated, it most likely has a stuck plunger or perhaps a broken plunger spring on #1 element. Check/change the pump oil. If it doesn't free, remove the side window on the pump and see what's going on...

If it's just air, start her on 2, crack #1 line open and wait until it clears. If the element is pumping, it will clear.

Thanks guys I pulled the little plate off side of pump full of rustey junk sprayed pb blast penetrateing oil let sit for awhile then blew it out with air hose got the plate soaking and little filter soaking in acetoner over night check the oil and it seeped out looks clean as new oil going to put it back together tommrow try bleeding again Thanks for pointing me to these little things I never new were there.
 
(reply to post at 20:35:18 07/20/16) [/quWell folks messed with ejc pump about three hours today heat is in double digits today here in eastern tenn got air condition in my garage but it didn't decide to quit there I have fuel to the ejc pump but still none on #1 it's about to go to the scrap yard.thanks for the advice :oops:
 
Hey guys still can't get the 3000 to start I have bleed every line pressurerized the took pleate off side all plungers are doing that they are supposed to far as I know something I noticed is no power on ignition how found out I was going to hook up a remote starter switch cause it's hard to operate switch I tried my ice pick tester could not find any hot power to use tried with key on and off shouldn't there be hot wire all the time enough rambling on could this be anything to with it still not at least running on two cylinders?
 
I am not sure about the Simms pump on a 70 3000. I am guessing these are inline minimec pumps similar to that on my Dexta, but mechanically governed. I am thinking that you should remove the overflow lines from the injectors and see if the return flow is the same on all three injectors by turning the engine over a few times. I would also have a fire extinguisher handy as I don't know how much goes back to the tank. I would normally try this on my Dexta tractor before suggesting you do it, however I have my injectors out right now for cleaning.

If fuel was coming out of the loosened No. 1 injector tube nut when you previously loosened it and there is nothing coming out of the overflow at the top of the injector then the nozzle valve is jammed. If fuel is returning at about the same volume on all three ejector tops then the no. 1 nozzle orifices are clogged.

If this is not a good thing to try now is the time for everyone else to chime in and nix this.
I don't expect any fire, but it is always best to play it safe.

It is also possible that the number one plunger and barrel are worn out. It depends on whether the number one poppet valve is working.
 
Make sure your lift pump is working and don't do this close to the house just in case. Are you sure there is fuel going to the No. 1 injector?

I am also not sure of what you meant about the condition of the tractor.
Is this Ford 3000 one you have had running in the past and it quit running a few days or weeks ago or did you just acquire it?

A little history on the tractor please.
 
Hey gentleman I have had tractor for about three years done some bush hogan two weeks I pressure washed the whole tractor packed it in edge of yard my wanted mow the yard so I went to move it and it didn't fire up as it usually did but it finally did start I moved into a nother lot it sat about week and hasn't started since I have drained fuel bleed every line took the side plate off the side of pump plungers seem to be working as crank the motor over but no fuel on# 3 lift pump took line loose solid fuel there same on all lines except 3 going to get some Marvil oil and mix 50/50 in the oil on pump got fuel mixed in tank with 5 gal diesal with 1 quart aft got clear line going to lift pump can see the mix going In pump as I said should there be one hot post on ignition switch tri to hook up a remote switch so I could watch all of the pump with no fire on ing switch but will turn over with key where does the heat come from to iignite the fuel on the three cylinders and yes fuel on no 1 and 2 but none on 3 should it run on two cylinders but rough?
 
Let me understand. It is No.3 injector/cylinder that is not firing, not No.1? Why the ATF fluid? Marvel Mystery Oil? It is possible you somehow got water in the system when you pressure washed it. Did you pressure wash it while the engine was hot?

I don't know whether I can help beyond this. I am too confused.
 
Yes the motor was running while pressure washed it I have then drained the fuel tank as I put a cock plug in that has a fuel shut off on it now cause old was broke off so I draind the tank while had the ole one out as to the aft read on another post that it might help free up the plunger if it indeed was sticking but pulled the plate off side of pump an watched it as my wife cranked it over it look like it was popping up and down but still no fuel on #3 with the line cracked open it does have oil in the pump as I opened the weep hole the oil look like new oil and feels like it too if there is water in it and doesn't come out of separator bleeders just don't under stand I have changed all fuel changed filters bleed every line but nothing on #3???
 
Someone else needs to give their input now that the chronology of events have been given. My tractor is a Dexta and I have no experience with Ford 3000 fuel systems just experience with Simms pneumatic injector pumps and indirect injection.

Could pressure washing a hot running engine do anything else beside cracking or warping the exhaust manifold?
 
Tractor ran fine for abut six hours of bush hoging but sat for couple of days was hard to start but finally started now is the problem thought filters were cloged hasn't ran since.but thanks for trying to help,all ideas will be greatly appericated :?:
 
Well folks ford with Simms pump is alive an well went with my own gut instincts probably the pros would not approve of some of my methods BUT THANKS for all replies :
 
It would be very interesting to know what you did regardless of the techniques you used.
I do not consider myself as a pro so if there is anything useful to put in our bag of tricks let us know.
