Okay BREWSKI,

I still have the regulator torn apart, got the valve kit but am still waiting on the diaphragms. However, I bench tested the fuel lockoff solenoid, the idle bypass solenoid and the idle trim injector. The fuel lockoff sucked the piston up in the body nicely with 12VDC applied, the idle bypass solenoid allowed flow only with 12VDC applied, and the injector I filled with denatured alcohol and tried to blow through it, when I gave it 12VDC a bit of brown stuff came out followed by clean denatured alcohol. I filled up the hose a couple of times with alcohol and blew through it. Then I soaked it in an ultrasonic cleaner for 20 min or so...I'm going to give it another half hour or so then push one more shot of denatured alcohol through it. I cleaned all the ports through the regulator and replaced the valves, now I just need the diaphragm kit so I can put everything back together. Everything seems to be checking out. The only things that I didn't check is for power at the actual connector for the idle bypass solenoid when cranking, and I'm not sure how to test for power at the injector, but I will hook a meter up to it and see if I get anything. I suspect that the idle trim injector was gunked up, and that's it. Will post results again when I have the truck put back together, hopefully tomorrow. There really isn't much else in this fuel system, is there?

If at first you don't succeed it's probably because you need more money.

Fact of the week
The word "okay" (or its abbreviation "OK") originated as a humorous misspelling. In the 1830s, a fad in Boston involved using abbreviations of intentionally misspelled phrases. "OK" stood for "oll korrect," a playful mispronunciation of "all correct".
