Bx2350 acts like staving for fuel

davideoftex · Sep 8, 2015

I have tried almost every thing. Removed tank to check for blockage, did the seat mod of removing one of the metal pieces, bypassed the fuse so that I had to kill the engine under the hood, replaced both filters and today the fuel pump. I have searched the web and see the same complaints and never see any remedy.
The only thing left is the injection pump, help please

I'll ask a couple question, you've probably already done them but I'll ask. Have you taken the fuel line off in various places to see if you have good flow, such as after the rear filter, it should flow well by gravity. I'd also try it before the main injection pump with the key on to make sure it's getting fuel there.

There was someone on this board that had the main injection pump go bad, but it's not common.

I also assume you have checked your diesel to make sure it's clean and doesn't have algae or a lot of dirt.

Yes I have good flow to the fuel pump, I have taken the fuel cap off to make sure it is venting. The fuel pump (new and the one I replaced) have the same pressure by using my finger as a gauge. The fuel is used up often so it's never old.

My next thought is using the other fuel pump, a Y from the tank to both fuel pumps check valves to engine for more pressure. The second fuel filter doesn't stay full. If I can't figure it out, a new tractor 13,000$&#55357;&#56834;, the grass keeps growing

My BX25 did the same, because of a parking brake that would not fully disengage. When I put a load on the engine it would stall. Once the dealer fixed it the problem never reoccured. Strange, but true.

I will check it out, thanks for your input

You will find a lot of posts about adding a Racor filter to the BX's. My rear filter would plug up, but maybe only once a year. I would cut that filter open and it never looked bad, but you could tell when you took the hoses off it was plugged up. I'm not saying thats your problem but the filters are so small the plug easy.

If you can see the second filter isn't filling up well, it almost has to be a plugged tank, filter, hoses etc.

My question would be "how old are the hoses?" could be when fuel draw is heavy when under load the hose is collapsing on the inside restricting fuel flow.

davideoftex · Sep 11, 2015

The hoses are in great shape, both filters are new.
It doesn't seem to have problems with full tank of fuel. When it gets low I will try and pressure the tank up and blow it all out although it flows free through hose

a racor as filter has been ordered

Crazy to get into 2 fuel pumps in my opinion. Whole new story now that you say "it doesn't seem to have problems with a full tank of fuel." What were your symptoms in the first place when you said it acted like starving for fuel ? Based on what I think we know, the extra fuel pressure of a full tank makes the problem go away ? Yet you put on a new fuel pump and have confirmed good fuel flow at the input to the injection pump ? Something just does not add up here. Seems to me like one of your tests or checks is in error. Maybe it is time to create your own fuel supply line from a hand-held (or held up by a wire or whatever) fuel container. Just like an IV bag of fluids in the hospital. Feed that new line into the injection pump inlet. That will tell you whether you have a problem in closer to the engine or back further upstream in the fuel path somewhere. Process of elimination from there.

^ Good advice & a simple way to partially isolate the fault & confirm or eliminate some suspects.

davesl708 · Sep 14, 2015

Hope this fixes the problem. Good luck with it.

dodge man · Sep 14, 2015

I was kind of thinking the same thing, maybe rig up a 1 or 2 gallon fuel can for a temporary basis.

davideoftex · Sep 20, 2015

Filter came in, so I cut grass about 30 minutes till it started cutting out. Removed mower, discounted fuel line and it was plugged. Took gas cap apart to try and blow the blockage out with air pressure to no avail. So I removed fuel tank washed it out very well. Let sit in sun for hours as I installed my new filter. When all was installed the new filter filled quickly and then the pump had good pressure toward the engine. Was going to cut grass for a couple hours but now the seat switch is being to sensitive.
I know I shouldn't because.... But I am going to bypass that switch. What is the easy way to bypass it. I promise not to fall off

JWR · Sep 24, 2015

If you can find the switch, all it does is provides continuity so if you jumper from one side of the switch to the other (or just take the wires off the switch and connect the two together) that solves the problem. Of course, be careful and use your head, but those blasted mechanisms designed to protect us from ourselves are a pain in part that uses that seat !

I just went through that with my 2360. I found the front fuel filter was plugged even though it had been replaced about 25 hours earlier. One interesting thing I noticed is that when trying get to start with the plugged filter the glow plugs made a very erratic sound. After new fuel filters installed the glow plug "clicking" was back to normal.

dodge man · Sep 24, 2015

I'm thinking the clicking you were hearing was actually the fuel pump and not the glow plugs. That also make sense, if the fuel filter was clogged, the fuel pump might make a different sound.

JWR · Sep 24, 2015

Yeah, as Dodge Man suggests, glow plugs don't make noises. Maybe the relay that feeds the glow plugs ? Maybe the starter solenoid? Might just be a coincidence. I can't think of any reason for the sound to change when you fix a clogged filter.

So davideoftex, what has happened and what is the rest of this (original starving for fuel) story ? I assume you got it fixed ?
