[DKC'sVFR]

I would like to get some input from you guys about my 86 700. I have been playing around with it trying to get it to start. I know you discussed probabilities regarding cause etc and that therewas another thread about much the same sort of "dieing" routine centering around the R/R. Let me throw some fuel on the fire and see if anybody has a word to say about what I am experiencing. I bought the bike for $500 from a courier who owned it 6 months before it started the dieing routine. I took off the tank and I was about to go for the regulator but I had to get gas to the carbs to see if it would light. No go. Took out the pump because the yokel I bought it from had lost the screw holding on the pump dust cap. wired said pump direct to Batt and it worked. Got out the VOM and started prodding at the harness for the pump. No manual. Been trying to down load one from the "Specifications forum" under "parts and manuals". No luck there. Tried to grab the 83-84 500 manual by waiting for about a day on two occasions only to have the download hang when it reached about 40-50%. in the wee hours of the morning. No luck with any of the the 750 manuals. The ones available for download can't be had off of the VFR site, even though they are PDF files and I have version 7.1. at least not by me. However it was glad to give up the Honda Common Manual and the owners manual that are available.

So I am trying to figure the pump wiring and I go to my local public library and pull out a CBR600 Haynes manual , which is the oldest honda manual they had, and the wiring diagram for a 99 shows a "fuel cut-off relay" with exactly the same wire code as the 86 VFR except for the control wire that comes out of the ICM. The CBR 's is black and blue, the VFR is yellow and green. I traced the yellow and green VFR control wire back to the ICM. When I turn on the ignition I get power to the Black feed line of the fuel cut off relay. In the split second when the key turns I get a blip of voltage at the outlet wire of the "Fuel cut off relay" and the pump make an attempt to click before the relay control wire coming from the ICM shuts down the flow of current through the fuel cut off relay. The relay is a 3 wire black box with Black/black and blue/and yellow and green wires going to it. The pump gets its power from the black and blue lead and then goes to ground on a green wire through the pump 2 wire connector. P.s. the 99 CBR has an additional "fuel pump transfer relay" that the 86 VFR does not have.

I am wondering if the entire starting/running problem is related to the yellowand green wire from the ICM.

Another strange thing that happened before I messed with the pump was that I did a spark test with 1 and 3 plugs removed. I got a nice yellow spark that I could see well in bright 100+ F soCal daylight. When I tried to light up the plugs in my garage later that night the plugs were dead.

I have not figured out the thread system yet. I am going to try to send this enquiry/thread back to Packman, VT Viffer and white knight if I can find out how. DeKC
