I have a OEM one coming I will install and report back. Thank you.

ufff...
hate it when they do that
our company does this too... always trying to get TVH parts
the only way i can get OEM is to specifically request it when placing the order.

i do alot of work on aerial lifts and it is imperative to use OEM oarts on those machines, i can't seem to get this through thier heads because they are always trying to give me aftermarket junk. I have to put OEM part only every time i order parts usually.

i've had too many aftermarket part failures for my liking so i just tell them OEM.

I got the forklift back in the shop checked for power and ground both were present solenoid does not click, I suspect it has failed. I will order a new one preferably a OEM one and report back.

It was my request for new it was overruled, I will recheck and report back. Thanks for the help

thats probably whats wrong
with something like that i would go with OEM
aftermarket parts (especially electrical parts like starters and solenoids etc) just arent made well and fail sooner

OEM may cost more but they usually are made better, last longer

like the old saying goes 'you get what you pay for' ;o)

Aftermarket

did you use OEM replacement part or aftermarket part?

Well came in this morning and used the fork lift now it won't shut off again it was good for a week, haven't checked anything yet.

awesome man
glad you got it

congrats :o)

While the solenoid was clicking,I replaced the solenoid it corrected the problem and the forklift shuts off. I bench tested the old one and it seem to work so I suspect the piston was worn and not closing off the fuel like a bad needle and seat on a gas engine. Thanks for the help.

ok so you verified it works with it removed
the problem with checking it while hooked up is that you will probably get a 0 volt reading, disconnect it and check the harness side (not the solenoid) and see if it is getting battery volts. If not then you will have to back trace the circuit through the harness till you find the issue. Check all the harness connectors for corrosion etc, if you run across any relays or circuit breakers check them as well.
Everything usually sprouts out from the fuse panel so since you did not find any issues there it is probably between the fuse panel and the solenoid somewhere.

But the fact that it seemingly is running without the solenoid working properly tells me there is still something wrong with that solenoid, the plunger or something.

I removed the solenoid checked it with power it pulled in I have already checked all the fuses.

the solenoid on the injection pump IS the fuel shutoff
pull it out and you will probably find it stuck like was mentioned earlier or a broken spring or something.

and when your checking for solenoid operation, when you turn on the key it should click, you should get voltage.

the fact the engine will crank and run with that not working (because you said earlier it has no voltage on it with key on) means it has to be defective.

check your fuses and see if any are blown, look around the steer column and under dash area and see if you can find any relays. that solenoid should be powered on when key is turned on.

and FYI... when you pull the solenoid out you may get some fuel running out, if this happens you may have to bleed it afterwards to get it to pull fuel again once you figure out this is the problem and get a new one installed. Most diesels don't like air in them and will not start if this happens.

Choking off the air.Where is the fuel shut off,there is a solenoid on the pump but I don't think it is the shut off. I don't see anything else?

i have a question...
if the fuel shutoff has no voltage the engine should not run

and on top of that since you say the engine will not shut off how are you shutting it down?

There is no power to fuel cut solenoid but when I jump it to battery it doesn't shut off.

Check the wire going to the fuel shut off solenoid valve for battery voltage with the key switch on, and again with the key switch off.
The fuel solenoid should only have battery voltage when the key is on, and 0 volts when the key is off.
If you find that you have 0 volts when the key is off, but the engine continues to run, the fuel shut off solenoid has stuck in the run position.
I have also run into some head scratcher problems many years past where a defective condition in an electrical system was causing the wiring to the shut off solenoid to stay energized after the key was turned off. But this was on a different piece of machinery, not a forklift.
So, you need to check to see if the shut off wire goes to 0 volts when the key is turned off while the engine is running too.

Fuel shut offs operate to let fuel flow when voltage is applied to them, and to stop the fuel flow when voltage is taken away from them. If it were the other way around, you would never be able to keep the battery from discharging while the engine was shut off.

Yes it is a diesel, is the fuel shut off on top of the injection pump, it seem to have no effect hooking power to it.

CDP40?
would this be a diesel unit by chance?

i'd check the fuel shutoff circuit
bad solenoid or wiring to it?
