No Power To FSS?

[Waystro]

Ahh the never ending saga of wiring problems. Here's what I'm batting now.
When key is turned to the on position the following comes on
Radio
Lights/Cab/dash.

What doesn't come on is the
GlowPlug light and I don't here the relay clicking.
Next is No power to the FSS(I think that's what it's called)
I swapped out my GlowPlug harness with a good one from the 86 still no change.
Thought?

maybe the main power switch on the bottom of the steering column in the cab.

Try the main engine harness plug. Follow it off the engine, over the valve cover. The main plug is a common problem point.

What else have you tested?
* Wipers
* Turn signals
* HVAC blower
* reverse lights

Did you check ALL fuses?

Here's what works
Turn signals
Ac Blower
Wipers

I looked in this thread and realized that mp GP controller is not hooked up

Key on power is usually a green wire with a red stripe. If you apply power manually to the IP connector with a jumper wire, and hear the glow plug controller energize, then that wire is not getting power from the chassis.

So run a jumper from the Battery to the ip right?

Yes

Ok so I hooked the jumper up it just clicks but I didn't hook the glowplugs up yet she really sounded like she wanted to start but the positive cable caught fire so done for tonight. How do I fix the fss issue?

Use a test light, and fire up your brain. Find out why there is no power there.

A wiring diagram would also help you.

Ya maybe the one in the manual I sent....

^^^^ +1; it isn't an "FSS issue". It's a "POWER to the FSS issue".

Haha forgot about that.

If I get time tonight I'll get my test light out and see what's going on. The switch that's on the steering column has power to all the wires but one(red wire with green stripe) if I remember correct the wires getting voltage but the switch isn't it's brand new from carquest but I might have to return it and get a new one.

 

[Waystro]

ok both of the ip connectors are getting power
red wire with green stripe has power. Maybe the pumps bad?

Just to confirm, does the FSS click when you connect its regular power feed wire (not the jumper) to it? If so, and if you've physically got fuel going into the IP but not coming out of it, that def. puts the focus on the IP.
