Well the injectors themselves never came out but as far as where the fuel line meets the injector, I cracked each one separately about a half turn until it was gushing fuel, then tightened it snugly and moved on to the net. I was hoping to fire t up and then purge some more air while it was running from each injector individually. Then shut it off and torque the lines to spec.

Was just trying to get a 12v reading from the fuel shut-off solenoid and I couldn't. Although I don't see where the power source is for those two little wires. It just goes up to a plug that plugs into the manifold.. So I'm still at a loss. Haha. This is super gay.

Run a jumper cable from the battery to the fss. But, it seems that if you are getting fuel to the injectors, the fss is working...Mark

With the key in the run position you should have 12v to the fss.

where do i adjust these "clicks" and what do you mean by them... are we talking on the linkage somewhere or actually on the throttle lever?

The throttle lever splines onto the throttle shaft going down into the pump top. By click i mean you adjust the splines one way or the other

When I got my donor 93 running...it sputtered and wouldn't run well for a few minutes. I had to hold my foot to the floor for quite some time before it cleared up and ran decent. I then had to re-adjust the idle setting...was too low.

But yeah it sounds like the throttle index is off.

runs! all she needed was a slight tweak... now i can only sit an wonder if that throttle index is perfect on the money or if it needs more fine tuning. its very hard to only get 1 tooth because the splines on that shaft are so **** small.
