JD 4100 Cranks No Start

[Bucky3d]

I have posted about this related problems and received great answers.
Problem:

Status: New Solenoid (works) tested by grounding to (wht Solenoid wire in connector) in/out great, wire seems to get hot if I ground too long.
Tested - turned key-on, tested volts from Blu/Gm - No volts, Tested Volts from Red OK
Plenty of Fuel in bowl (new Filter), New Fuel (Relay K3)

I believe I have a short in one of my wires and I would like to verify my circuit from starting (KEY-ON-S1) to the
Fuel Relay (K3) to the Fuel Shutoff Solenoid (Y2). Wire Function:
Key-On(S1): Red Wire (400/401)----->Fuel Relay (K3)

Fuel Relay (K3):
1. Wires Into Relay:
a. ------->(400/401 Red) from Key-On (Power).
b. ------->(811 Blu/Gm) From? Safety Switches?" ___________________________________________

2. Wires Out to (connector X4):
c. ------->connector (Blk)---> Solenoid (Blk) Ground OK
d. ------->Into (650 Blu) ---> connector ----->(Wht) to Soleniod (Y2): Is this main power for start (High ohms?)
e. ------->Into (655 Gm)----> connector----->(Red) to Soleniod (Y2): Is this Alternative for running (low ohms?)
f. ------->Into (656 Gm) ---> (A2 Control Mod): ??_______________________________________________

3.Solenoid:
g.connector ----->(Wht) to Soleniod (Y2): (I ground this wire directly to white wire and Solenoid Worked)
h.connector------>(Red) to Soleniod (Y2): Is this Alternative for keeps running (low ohms)?

I really would appreciate your feedback or suggestions to curing this problem.

I asked a mechanic on a prior problem on the 4100, my son put regular gas vs diesel :ashamed:and ran->stop-Drained-filled diesel and the mechanic said that is all I should have to do. Drain the lines and the JD4100 are self bleeders no need to bleed the lines manually.
By another mechanic - he told me to buy a Fuel Injector ($$$$$) and new Injectors... is this right over $1500 to repair if the problem?

I'm alittle lost Bucky.. does it run WITHOUT the solenoid.?? Try it..
IF it doesn't.. look at how the sol. works.. it PUSH'S the control rack to shut it off.. & a spring pulls it to RUN.
So reach in the hole w/ your finger, a cut-off coat hanger or a scribe & see/FEEL if the pumps control rack is moving..
U should be able to push it & have it return..
IF this problem is because the helper put gas in it{no lube in gas}.. the rack is probably stuck.??
Have the throttle position in the RUN WIDE OPEN position when checking the rack..
Let us know..

No now the solenoid is not clicking. can test it directly from the (+) side of the battery to the white connection leading to the solenoid without hurting the solenoid. I think I did this before and it withdrew the pen of the Solenoid.

By the way which wire is the high voltage and is the low? White or red?

I lost being a novice at this but try anything (frustrated). What is a rack and located I am hoping I don't have to replace the injector pump.... Hard? I see the cams, I see a sliding bar on the side, and the return fuel and 3 injector outlets. Is there picture

The "slide bar" IS the PUMP control rack.. IT links up to the ENGINES control rack..
The solenoid push's on the pump control rack in most cases..

On the sol.>>
Black is ground-
White is PULL+ {HI AMP}
Red is RUN{hold} + low amp
They run thru relays that switch from hi amp to low amp.. You'll hafta get a work shop manual to find out where & which..

In getting to the rack, on the side There are four screws and a little plate do I take that offer and they were to have access to the rack

 

[Bucky3d]

By the way Thank You so much

reread post #2.. 3rd sentence.
OR.. if it has an access plate BELOW the inj. pump, remove it & see if it will get u to the control rack.
