Re: [DML] RE: Frequency valve hose

Well I made some progress this weekend, I just not sure how I did it. I was checking for spark in the morning with one of those induction light pens. It showed spark from the coil but no spark to the plugs. I had disconnected a few wires to the distributor when I was working on the clutch slave and was not looking forward to removing the fuel distribution again to check the plug wires. I loosen the fuel distribution and got my hand on the distributor but really could grab the wires. I had to leave so I tighten things up and left it.

Later in the day my trusty assistant (daughter) and I went to test the plug wires again just to be sure there was no spark. I unplugged the CSV to cut down on the fuel being pumped into the engine. She turned the ignition and low and behold it started. A bunch of white smoke came out of the tail pipes or a few minutes but it ran. It ran a little rough and the idle was surging but it didn't die.

I am thinking the fuel distribution unit might have loosened the plug on the distributor from the coil and and I fixed it when I loosened and re-tighten everything. Any one else have a theory? What would cause the white smoke?

Steve,

You don’t need to crank the engine to get the frequency valve to start buzzing. It is switched on by the same relay than the fuel pump. So, wherever the pump is running the FV has to run. Switch the key on and the pump should prime the system for about a second or so. If it doesn’t you can switch the key off and back on quickly. Listen for the fuel pump hum from the front and a loud buzz from the FV in the back.

If the FV does not run it will cause a very lean condition and the engine might not start.

Good luck!

I checked the electrical connections in the area I was working. It is hard to tell if the frequency valve is buzzing while the engine is cranking. Can a problem with the valve cause a no start? The hose to the valve broke just at the hose barb so I was able to shorten it and pushed it back on, not easy to do. I'll check for spark this weekend.

And yes I am pretty sure I put the hoses back correctly, it did start which is when I found the WOR hose leaking. But I'll check again.

Did any of the wires around the coil get loosened? The ballast, etc.? The frequency valve is buzzing? I would check the wiring carefully in case you loosened one. Any chance the fuel hoses were not reinstalled in the correct location? How did you get the frequency valve hose back on? Any chance you plugged the valve?
